Claudia Goldin Wins Nobel in Economics for Studying Women in the Work Force

by

Her research uncovered the reasons for gender gaps in labor force participation and earnings. She is the third woman to win the prize.The Nobel Memorial Prize in Economic Sciences was awarded on Monday to Claudia Goldin, a Harvard professor, for advancing the world’s understanding of women’s progress in the work force.Dr. Goldin is the third woman to have won the economics Nobel, which was first awarded in 1969, and the first one to be honored with it solo rather than sharing in the prize.Who is the winner?Claudia Goldin, 77, is the Henry Lee Professor of Economics at Harvard University. She has long been a trailblazer in the field — she was the first woman to be offered tenure in Harvard’s economics department, in 1989.She was asleep when the call informing her of the prize came in — she had gotten up earlier to let the dog out but had gone back to bed. She said in an interview that she was “delighted.”She saw a woman winning the economics award on her own as a sort of “culmination” after years of “important changes” toward more gender diversity in the field.Why did the committee say she received the prize?The Nobel committee announced the award in Stockholm. The committee praised Dr. Goldin for her research into female employment, which showed that employment among married women decreased in the 1800s, as the economy moved away from agricultural and toward industry. Women’s participation then increased in the 1900s, as the service sector began to expand as a part of the economy.She also illustrated that the process of closing the gender wage gap has been uneven over the course of history. Recently, progress in closing it has been halting: Today, Women in the United States make a little over 80 cents for every dollar a man makes.In the past, gender wage gaps could be explained by education and occupation. But Dr. Goldin has shown that most of the earnings difference is now between men and women in the same jobs, the Nobel committee said. Notably, it kicks in after the birth of a woman’s first child.In a 15-year study of business school students at the University of Chicago, for instance, Goldin and her colleagues found in one paper that the gap in pay started to widen a year or two after a woman had her first baby.“Claudia Goldin’s discoveries have vast societal implications,” said Randi Hjalmarsson, a member of the committee and professor of economics at the University of Gothenburg.Dr. Goldin said that she hoped people would take away from her work how important long-term changes are to understanding the labor market.“We see a residue of history around us,” she said, explaining that societal and family structures that women and men grow up in shape their behavior and economic outcomes.While there has been “monumental progressive change, at the same time there are important differences,” she said, and those differences often tie back to women doing more work in the home. “We’re never going to have gender equality until we also have couple equity.”Who won the 2022 Nobel for economics?Last year, the award went to Ben S. Bernanke, the former Federal Reserve chair, along with Douglas W. Diamond of the University of Chicago and Philip H. Dybvig of Washington University in St. Louis. They won for work that has reshaped how the world understands the relationship between banks and financial crises.The economics prize was established in memory of Alfred Nobel by Sweden’s central bank and is awarded by the Royal Swedish Academy of Sciences.Who else has won a Nobel Prize this year?The award for physiology or medicine went to Katalin Kariko and Drew Weissman for their discoveries that led to the development of effective vaccines against Covid-19.The prize in physics was shared by Pierre Agostini, Ferenc Krausz and Anne L’Huillier for techniques that illuminate the subatomic realm of electrons.The award for chemistry went to Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov for the discovery and development of quantum dots, nanoparticles so small that their size determines their properties.The literature prize went to the Norwegian novelist, poet and playwright Jon Fosse “for his innovative plays and prose which give voice to the unsayable.”The Nobel Peace Prize was awarded to Narges Mohammadi, Iran’s most prominent human rights activist and an inmate in the country’s notorious Evin Prison, “for her fight against the oppression of women in Iran and her fight to promote human rights and freedom for all.” More

    Harry Markowitz, Nobel-Winning Pioneer of Modern Portfolio Theory, Dies at 95

    by

    He overturned the traditional approach to buying stocks by examining the relationship between risk and reward.Harry M. Markowitz, an economist who launched a revolution in finance, upending traditional thinking about buying stocks and earning the Nobel in economic science in 1990 for his breakthrough, died on Thursday in San Diego. He was 95.The death, at a hospital, was caused by pneumonia and sepsis, Mary McDonald, a longtime assistant to Dr. Markowitz, said.Until Dr. Markowitz came along, the investment world assumed that the best stock-market strategy was simply to choose the shares of a group of companies that were thought to have the best prospects.But in 1952, he published his dissertation, “Portfolio Selection,” which overturned this common sense approach with what became known as modern portfolio theory, widely referred to as M.P.T.The heart of his research was grounded in the basic relationship between risk and reward. He showed that the risk in any portfolio is less dependent on the riskiness of its component stocks and other assets than how they relate to one another. It was the first time that the benefits of diversification had been codified and quantified, using advanced mathematics to calculate correlations and variations from the mean.This breakthrough insight and its corollaries have now permeated all aspects of money management, with few professionals unfamiliar with his work.“Modern portfolio theory has gone from the halls of academia to investment management mainstream, or from gown to town,” Robert Arnott, chief executive of Research Associates, a large investment manager in Newport Beach, Calif., said in a videotaped interview with Dr. Markowitz.When Dr. Markowitz heard one of his peers describe how his work had brought “a process” to what had been, until the 1950s, the “haphazard” creation of institutional portfolios, he knew he deserved his reputation as the father of modern portfolio theory, he said.“That moment was one of these things where you feel a chill run up your spine,” he said. “I understood what I had started.”In 1999, the financial newspaper Pensions & Investments named him “man of the century.”Related work on investments led Dr. Markowitz to be regarded as a pioneer of behavioral finance, the study of how people make choices in practical situations, as in buying insurance or lottery tickets.Recognizing that the pain of loss typically exceeds the joy of comparable gain, he found it crucial to know how a gamble is framed in terms of possible outcomes and the size of the stakes.Dr. Markowitz won renown in two other fields. He developed “sparse matrix” techniques for solving very large mathematical optimization problems — techniques that are now standard in production software for optimization programs. And he designed and supervised the development of Simscript, which is used for programming computer simulations of systems like factories, transportation and communications networks.In 1989 Dr. Markowitz received the John von Neumann Theory Prize from the Operations Research Society of America for his work in portfolio theory, sparse matrix techniques and Simscript.His focus was always on applying mathematics and computers to practical problems, particularly involving business in uncertain conditions.“I’m not a one-shot Nobel laureate — only doing one thing,” Dr. Markowitz said in an interview for this obituary in 2014. Although he was 87 at the time, he was embarked on a monumental analysis of securities risk and return. The seminal 1952 paper, in The Journal of Finance, was expanded into his best-known work, “Portfolio Selection: Efficient Diversification of Investments,” in 1959.Harry Max Markowitz was born on Aug. 24, 1927, in Chicago, the only child of Morris and Mildred Markowitz, who owned a small grocery store. In high school he began to read the original works of Darwin and such classical philosophers as René Descartes and David Hume. In financial terms, Hume’s work lay behind the maxim that past performance is not a guide to the future.He continued on this track in a two-year bachelor’s program at the University of Chicago, where, inspired in part by Hume’s focus on the uncertainty of knowledge, he decided to pursue economics.It was in graduate school, where he studied under Milton Friedman and other eminent economists, that a chance conversation on possible dissertation topics led to his work applying mathematical methods to the stock market.The basic concepts of portfolio theory came to Dr. Markowitz one afternoon in the library while reading an investment book by the economist John Burr Williams.Dr. Markowitz was awarded the Nobel in economic science in 1990, sharing it with Merton H. Miller and William F. Sharpe.Sandy Huffaker for The New York Times“Williams proposed that the value of a stock should equal the present value of its future dividends,” Dr. Markowitz wrote in a brief autobiography for the Nobel committee. “Since future dividends are uncertain, I interpreted Williams’s proposal to be to value a stock by its expected future dividends.”But if investors were interested only in the expected values of securities, he figured, then that implied that the best, or maximized, portfolio would consist of the single most appealing stock.“This, I knew, was not the way investors did or should act,” he concluded. “Investors diversify because they are concerned with risk as well as return.”He set out to measure the relationships among a diverse assortment of stocks to construct the most efficient portfolio, and to chart what he called a “frontier,” where no additional return can be obtained without also increasing risk.At the RAND Corporation, during stints in the 1950s and ’60s, Dr. Markowitz worked on practical problems in American industry that required the development of simulation methods; he created the Simscript language to reduce their programming time.He went on to work for IBM and General Electric, where he built models of manufacturing plants. In 1962 he co-founded the California Analysis Center Incorporated, a computer-software company that would become CACI International.Dr. Markowitz’s first two marriages, to Luella Johnson and Gloria Hardt, ended in divorce. In 1970 he married Barbara Gay. She died in 2021.Mr. Markowitz is survived by two children from his first marriage, Susan Ulvestad and David Markowitz; two from his second, Laurie Raskin and Steven Markowitz; his wife’s son from a previous marriage, James Marks; 13 grandchildren; and more than a dozen great-grandchildren. He lived in San Diego.Dr. Markowitz in his office in 2012. “I’m not a one-shot Nobel laureate — only doing one thing,” he said in an interview in 2014.Sandy Huffaker for The New York TimesIn 1968 Dr. Markowitz began to manage a successful hedge fund, Arbitrage Management Company, based on M.P.T., that is believed to have been the first to engage in computerized arbitrage trading.Dr. Markowitz was a professor at Baruch College of the City University of New York when he was awarded the Nobel in economic science, sharing it with Merton H. Miller and William F. Sharpe. He also served on the faculties of Rutgers University, the University of Pennsylvania’s Wharton School, the University of California at Los Angeles and finally at the Rady School of Management at the University of California, San Diego.After submitting his landmark dissertation, Dr. Markowitz took a job at RAND and was fully confident that “I know this stuff cold” when he returned to Chicago in 1955 to defend it.Within a few minutes, however, Professor Friedman told him that while he could find no mistakes, the topic was extremely novel. “We cannot award you a Ph.D. in economics for a dissertation that is not economics,” he said.At this point, Dr. Markowitz recounted, “my palms began to sweat” and he was sent into a hallway, where he waited for about five minutes.Finally, a panel member emerged and said, “Congratulations, Dr. Markowitz.”Dr. Markowitz insisted that he had not suspected the joke.Alex Traub More

    Robert E. Lucas Jr., Nobel-Winning Conservative Economist, Dies at 85

    by

    Challenging the theories of John Maynard Keynes, he questioned the idea that government intervention could help steer the economy.Robert E. Lucas Jr., a contrarian Nobel laureate in economics who undergirded conservative arguments that government intervention in fiscal policy is often self-defeating, died on Monday in Chicago. He was 85.His death was announced by the University of Chicago, where he began teaching as a professor in 1975 and remained a professor emeritus until his death. The announcement did not cite a cause.In awarding the Nobel Memorial Prize in Economic Sciences in 1995 to Professor Lucas, the fifth winner in economics from the University of Chicago in six years, the Swedish Royal Academy of Sciences described him as “the economist who has had the greatest influence on macroeconomic research since 1970.”While he propounded a number of groundbreaking if sometimes controversial theories, Professor Lucas was best known for his hypothesis of “rational expectations,” advanced in the early 1970s in a critique of macroeconomics.In that critique, he challenged John Maynard Keynes’s long-established doctrine that government could manipulate the economy to achieve certain outcomes through reflexive interventionist policies, such as changing interest rates or taking other steps to increase or curb inflation or reduce unemployment.In the real world, Professor Lucas maintained, consumers and businesses make their decisions on the basis of rational expectations drawn from their own past experiences.“His idea was that macroeconomic models grounded in lots of equations are based primarily on past behavior,” said David R. Henderson, a research fellow with Stanford University’s Hoover Institution in California and an economics professor at the Naval Postgraduate School in Monterey. “But if people learn from what government does” and respond accordingly in their own self-interest, “those models will poorly predict future behavior.”As a result, Professor Lucas said, government economic policies can be self-defeating by failing to achieve their intended outcomes.As the economics columnist Leonard Silk wrote in The New York Times in 1983, “If people understand and anticipate what government is doing — for instance, in trying to accelerate economic growth by speeding up the increase in the money supply — workers will increase their wage demands and businesses will raise prices, to protect themselves against future inflation, thus negating the government’s intention of increasing real growth.”In an agenda with conservative implications for economic policy, Professor Lucas maintained that government spending that supplants private investment is counterproductive; that the money supply is what matters most; and that policies to reduce inequality by redistributing income, though “seductive,” are “in my opinion the most poisonous” to sound economics.He also favored eliminating taxes on capital gains, or on any income derived from capital. And he embraced supply-side economics, which calls for increasing the supply of goods and services while cutting taxes to promote job creation, business expansion and entrepreneurial activity.“The supply-side economists,” he said in a 1993 interview, “have delivered the largest genuinely free lunch that I have seen in 25 years of this business, and I believe we would be a better society if we followed their advice.”In 1995, not long after eight years under President Ronald Reagan, a champion of supply-side, and four under another Republican, George H.W. Bush, Professor Lucas concluded that “the U.S. economy is in excellent shape,” in part because “the government is not trying to do things with economic policy that it isn’t capable of doing.”And, he said, the same principles that encouraged economic growth in rich countries could be applied to economic development in poorer ones.In a 1988 lecture titled “What Economists Do,” Professor Lucas explained: “We economists have to be storytellers. We do not find that the realm of imagination and ideas is an alternative to, or a retreat from, practical reality. On the contrary, it is the only way we have found to think seriously about reality.”Professor Lucas, right, with three other Nobel laureates in economics from the University of Chicago, from left: James Heckman, Roger Myerson and Gary Becker. Kamil Krzaczynski/European Pressphoto AgencyRobert Emerson Lucas Jr. was born in Yakima, Wash., on Sept. 15, 1937. His mother, Jane (Templeton) Lucas, was a fashion artist. His father ran an ice-cream parlor that went broke during the Depression, after which the family moved to Seattle, where Robert Sr. became a steamfitter in the shipyards and then, after World War II, a welder in a commercial refrigerator company. Years later, though lacking a college degree or any training in engineering, he rose to become the company’s president.Before his father’s fortunes changed, however, Robert Jr., hoping to become an engineer, needed a scholarship to attend college and was offered one by the University of Chicago, though it didn’t have an engineering school. Lacking the nerve to study physics, he said, he became a history major. He graduated in 1959.He then enrolled in a graduate program in economics at the University of California, Berkeley. But, again needing financial support, he returned to the University of Chicago, where he studied under the conservative economist Milton Friedman, who would receive the Nobel in economics in 1976. Professor Lucas earned his doctorate in economics in 1964.He taught at what is now Carnegie Mellon University from 1963 to 1974, then returned to the University of Chicago as a professor in 1975.In 1959 he married Rita Cohen, a fellow student at Chicago. They separated in 1982 and divorced several years later. Among his survivors are their sons, Stephen and Joseph; his partner, Prof. Nancy L. Stokey, with whom he collaborated on some of his research at the University of Chicago; a sister, Jenepher Spurr; a brother, Peter; and five grandchildren.Six years before Professor Lucas won his Nobel, his estranged wife expressed great faith in his future. Her lawyer inserted a clause in their divorce agreement stipulating that she would receive half of any Nobel money he might receive if the honor was awarded before Oct. 31, 1995. He received the prize barely three weeks before that deadline.Professor Lucas was philosophical about collecting $300,000 instead of the full $600,000. He might have balked during the divorce negotiations, he said, if he had had a greater rational expectation that he would become a Nobel laureate.“A deal is a deal,” he said at the time. “She got the whole house. Getting half of the prize was better than nothing.” More

    David Card, Joshua Angrist and Guido Imbens Win Nobel in Economics 2021

    by

    David Card has made a career of studying unintended experiments to examine economic questions — like whether raising the minimum wage causes people to lose jobs.Joshua D. Angrist and Guido W. Imbens have developed research tools that help economists use real-life situations to test big theories, like how additional education affects earnings.On Monday, their work earned them the 2021 Nobel Memorial Prize in Economic Sciences.All three winners are based in the United States. Mr. Card, who was born in Canada, works at the University of California, Berkeley. Mr. Angrist, born in the United States, is at the Massachusetts Institute of Technology, and Mr. Imbens, born in the Netherlands, is at Stanford University.“Sometimes, nature, or policy changes, provide situations that resemble randomized experiments,” said Peter Fredriksson, chairman of the prize committee. “This year’s laureates have shown that such natural experiments help answer important questions for society.”The recognition was bittersweet, many economists noted, because much of the research featured in the prize announcement was co-written by Alan B. Krueger, a Princeton University economist and former White House adviser who died in 2019. The Nobels are not typically awarded posthumously. Despite that note of sadness, the economics profession celebrated the news, crediting the winners for their work in changing the way that labor markets in particular are studied.“They ushered in a new phase in labor economics that has now reached all fields of the profession,” Trevon D. Logan, an economics professor at Ohio State, wrote on Twitter shortly after the prize was announced.Mr. Card’s work has challenged conventional wisdom in labor economics — including the idea that higher minimum wages led to lower employment. He was a co-author of influential studies on that topic with Mr. Krueger, including one that used the border between New Jersey and Pennsylvania to test the effect of a minimum wage change. Comparing outcomes between the states, the research found that employment at fast food restaurants was not negatively affected by an increase in New Jersey’s minimum wage.Mr. Card has also researched the effect of an influx of immigrants on employment levels among local workers with low education levels — again finding the impact to be minimal — and the effect of school resource levels on student education, which was larger than expected.“I’m sure that if Alan were still with us, that he would be sharing this prize with me,” Mr. Card said in a news conference, after recognizing Mr. Krueger’s contributions. He also noted that initially, when it came to the minimum wage study, “quite a few economists were quite skeptical of our results.”David Neumark, an economist at the University of California, Irvine, who co-wrote a paper contesting Mr. Card and Mr. Krueger’s findings in the minimum wage study, said he still thought the work had data issues — but added that there was no doubt that the methodology was important.“They’ve all done great work — they’ve changed the way that labor economists do research,” Mr. Neumark said of the three winners.Mr. Angrist and Mr. Krueger tried in the early 1990s to gauge how much benefit people derive from extra years of education. To figure it out, they took advantage of the fact that students born earlier in the year can legally leave school earlier than those born later in the year. Those born earlier tended to get less education and also earned less later on. The effect of an additional year of education, they estimated, was a 9 percent increase in income.That study helped spur the additional work on research methods that Mr. Angrist and Mr. Imbens later carried out. That contribution has reshaped the way researchers think about and analyze natural experiments, according to the Nobel committee.The pair showed that it was possible to identify a clear effect from an intervention in people’s behavior — like a subsidy that might encourage people to ride bicycles to work — even if a researcher could not control who took part in the experiment, and even if the impact varied across individuals. They also came up with a transparent framework for such research that has increased trust in it.“The challenge, for me, has always been trying to understand, when people do empirical work, what exactly the methodological challenges are,” Mr. Imbens said via telephone in a news conference for the announcement.Two American economists affiliated with Stanford, Paul R. Milgrom and Robert B. Wilson, won the 2020 Nobel in economics for improvements to auction theory. Abhijit Banerjee and Esther Duflo of M.I.T. and Michael Kremer of Harvard University won in 2019 for their experiment-based research in development economics.The award, formally called the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel, has been given out since 1969.Because the award is announced in the middle of the night on the United States’ West Coast, two of this year’s recipients were woken up by phone calls from Sweden informing them of their prize.Mr. Imbens said he was asleep when he received the call from the prize committee — around 2 a.m. — and was “absolutely stunned” to hear the news. He said he was pleased to win it alongside friends, noting that Mr. Angrist was the best man at his wedding.Mr. Card thought that a friend of his — whom he identified only as Tim — was pulling a prank on him, he said.“But then the phone number actually was a Swedish phone number,” he said.

    H. Jack Geiger, Doctor Who Fought Social Ills, Dies at 95

Jack Geiger, Doctor Who Fought Social Ills, Dies at 95He used medicine to take on poverty, racism and the threat of nuclear destruction. Two groups he helped start won Nobel Peace Prizes.Dr. H. Jack Geiger in 2012. He believed doctors should use their expertise and moral authority to improve conditions like poverty, hunger, discrimination, joblessness and lack of education.Credit…Angel Franco/The New York TimesDec. 28, 2020, 3:17 p.m. ETDr. H. Jack Geiger, who ran away to Harlem as a teenager and emerged a lifelong civil rights activist, helping to bring medical care and services to impoverished regions and to start two antiwar doctors groups that shared in Nobel Peace Prizes, died on Monday at his home in Brooklyn. He was 95.His death was confirmed by David Shadrack Smith, his stepson.Dr. Geiger was a leading proponent of “social medicine,” the idea that doctors should use their expertise and moral authority not just to treat illness but also to change the conditions that made people sick in the first place: poverty, hunger, discrimination, joblessness and lack of education.“Jack redefined what it meant to be a physician,” said Dr. Irwin Redlener, the founding director of the National Center for Disaster Preparedness at Columbia University and the co-founder of the Children’s Health Fund. He added, by email, “He felt it was our right and responsibility as doctors to ‘treat’ hunger, poverty and disparities in health care, as directly and openly as we treat pneumonia or appendicitis.”The social order, not medical services, determines health, Dr. Geiger said in “Out in the Rural,” a short documentary film made in 1970 about the first community health center in Mississippi. “I’ve never seen any use in what I call the Schweitzer bit,” he added, referring to the humanitarian Dr. Albert Schweitzer, “which is the idea that you stand around in whatever circumstances laying hands on people in the traditional medical way, waiting until they’re sick, curing them and then sending them back unchanged into an environment that overwhelmingly determines that they’re going to get sick.”In the 1960s, Dr. Geiger was a co-founder, with Dr. Count Gibson, of community health centers in South Boston and in Mound Bayou, in the Mississippi Delta. They provided desperately needed health care but also food, sanitation, education, jobs and social services — what Dr. Geiger called “a road out” of poverty. The centers inspired a national network of clinics that now number more than 1,300 and serve about 28 million low-income patients at more than 9,000 sites.“I don’t know if some of the Mississippi white power structure cares about dead Black babies or not,” Dr. Geiger said in the film, about the first center in Mississippi. “But if they don’t, even they can’t afford to say so publicly. We have been able to enter and to do things under the general umbrella of health that would have been much harder to do if we’d said we were here for economic development or for social change per se.”Dr. Geiger, second from left, treating a baby in Bolivar County, Miss., where he co-founded a community health center.Credit…Dan Bernstein, UNC Southern Historical CollectionDr. Geiger was a founding member of two advocacy groups, Physicians for Social Responsibility, which shared the 1985 Nobel Peace Prize for its efforts to end the nuclear arms race, and Physicians for Human Rights, which shared the 1997 prize for working to ban land mines.He rallied doctors in the Cold War era to speak out against what he saw as a myth being promoted by the government, that nuclear war could be survivable. On the contrary, he insisted, hospitals would be quickly overwhelmed, and even victims with treatable injuries would perish.Drawing physicians out of the clinic and into the political fray “was a really signal event,” said Dr. Robert Gould, a pathologist in San Francisco and president of the Bay Area chapter of Physicians for Social Responsibility.In an email for this obituary sent in 2012, Dr. Geiger said he was driven in part by an outrage over injustice.“I’ve been angry,” he wrote, “seeing terribly burned children in Iraq after the first Gulf war, or interviewing torture victims in the West Bank, or listening to Newt Gingrich say ghetto kids should learn to be part-time janitors and clean toilets (in another country, they called that Bantu Education). So anger doesn’t vanish, but is replaced by a determination to do something.”Home Was a Way StationHerman J. Geiger was born on Nov. 11, 1925, in Manhattan. (It was unclear what the J. stood for, but he was mostly called Jack throughout his life.) His father, Jacob, born in Vienna, was a physician; his mother, Virginia (Loewenstein) Geiger, who came from a village in central Germany, was a microbiologist. Both parents, who were Jewish, had emigrated to the United States as children. Mr. Geiger grew up on the Upper West Side of Manhattan, and their home was often a way station for relatives fleeing the Nazis.“The last to appear were some cousins from my mother’s birthplace, Kirtorf,” Dr. Geiger said in the email. “When they got their visas to come to the U.S., they said, the Nazi authorities were furious. On the night before their departure, the authorities ordered all their neighbors to go out at twilight and stone their house. The neighbors all dutifully gathered — and threw loaves of bread instead.”That story, Dr. Geiger said, taught him not to stereotype.He skipped so many grades in the city’s public schools that he graduated from Townsend Harris High School (then in Manhattan, now in Queens) at 14. Too young to start college, he learned typing and shorthand and went to work as a copy boy for The New York Times. He also began hanging out at jazz joints, listening to Billie Holiday, Art Tatum and Fats Waller. His parents were often beside themselves, waiting up for him and sometimes even calling the bars to ask if “Jackie” was there.Jack soon ran away from home and turned up, suitcase in hand, in Harlem’s Sugar Hill section on the doorstep of Canada Lee, a Black actor whom he had seen on Broadway and had gotten to know after talking his way backstage. Mr. Lee, once a teenage runaway himself, let young Jack sleep on the couch — after consulting with his parents — and though Jack sometimes returned home, he spent most of the next year in Harlem. The year was 1940, and Mr. Lee’s home was a hub for writers, actors and musicians — Langston Hughes, Richard Wright, Orson Welles, Paul Robeson, Billy Strayhorn, William Saroyan. The Black guests told harrowing stories of racism, and Harlem was seething over the mistreatment of Black troops at military bases in the South. Jack Geiger took it all in.In 1941, with a loan from Mr. Lee, he began studying at the University of Wisconsin. He worked nights at a newspaper, The Madison Capitol Times. Because Madison had a curfew for anyone under 18, he said, “I am probably the only police reporter in history who had to get a special pass to be out at night.”In 1943, after meeting James Farmer, the founder of the Congress of Racial Equality, Mr. Geiger started a chapter of the group in Madison. It was the height of World War II, and after turning 18 that year he left school to enlist in the merchant marine, which he chose because it was not racially segregated.When Dr. Geiger arrived in the all-Black Mississippi Delta town of Mound Bayou in the 1960s, he found conditions there as desperate as those he had seen in the poorest areas of South Africa.Credit…Dan Bernstein, UNC Southern Historical CollectionRabble Rouser for JusticeDischarged in 1947, Dr. Geiger enrolled as a pre-med student at the University of Chicago. He discovered racial discrimination there — Black patients being excluded from certain hospitals, qualified Black students being rejected by the medical school. He fought the policies for three years and ultimately helped organize a 1,000-strong faculty and student protest strike — an activity virtually unheard of in that era.He paid a price for his rabble-rousing. The American Medical Association wrote to medical schools warning of his “extracurricular activities.” No school would take him. He had, in effect, been blackballed.Dr. Geiger went back to journalism for the next five years, as a science and medicine editor for the International News Service (later part of United Press International). It was, he said, “a gorgeous education” that let him read journals, attend conferences, interview researchers and, significantly, meet deans whom he could lobby to let him into medical school. In 1954, at 29, he was admitted to what is now Case Western Reserve University’s medical school in Cleveland.During his last year at Case Western, he traveled to South Africa and worked with two physicians who were setting up a health center in an impoverished, disease-ridden region of the country called Pholela, which was then a Zulu reserve. A key to the center’s success was that local people — its own patients — worked there and helped run it.For five months Dr. Geiger took care of patients, visiting thatch huts and cattle kraals, meeting traditional healers and seeing the huge improvements — pit latrines, vegetable gardens, children’s feeding programs — that the health center had brought to the region.“I learned a little Zulu, including the three oral clicks in that language, which always made me drool, to the hilarity of my African teachers,” he wrote in a chapter he contributed to the 2013 book “Comrades in Health.”Dr. Geiger’s time in Africa made him want a career in international health. He trained in internal medicine at Boston City Hospital and in epidemiology at the Harvard School of Public Health.In the “freedom summer” of 1964, he traveled to Mississippi to help care for the civil rights workers who were pouring into the Deep South to campaign for voting rights. The next year, he organized medical care for the people who marched with the Rev. Dr. Martin Luther King Jr. from Selma to Montgomery, Ala.“I took a long look around,” Dr. Geiger recalled of his first visit to Mississippi. He saw conditions much like those in South Africa: families living in shacks with no clean drinking water, toilets or sewers; sky-high rates of malnutrition, illness, infant death and illiteracy; few or no opportunities for residents to better themselves and escape. He did not have to travel to Africa to find people in trouble, he realized.Mound Bayou in the 1960s.

Johnson, the war on poverty had begun, and the Office of Economic Opportunity had been created to pay for projects to help the poor. Sponsored by Tufts University and armed with grants from the opportunity office, Dr. Geiger, Dr. Gibson, Dr. John Hatch and others set up a health center in Mound Bayou, Miss., a poor, Black small town where most people were former cotton sharecroppers whose way of life had been wiped out by mechanization.The center was a copy of the Pholela project. The clinic, which opened in 1967, treated the sick but also used its grant money to dig wells and privies and set up a library, farm cooperative, office of education, high-school equivalency program and other social services.The clinic “prescribed” food for families with malnourished children — to be purchased from Black-owned groceries — and the bills were paid out of the center’s pharmacy budget.The governor complained, and a federal official was sent to Mound Bayou to scold Dr. Geiger for misusing pharmacy funds, which, the official said, were meant to cover drugs to treat disease.“Yeah,” Dr. Geiger replied, “well, the last time I looked in my medical textbooks, they said the specific therapy for malnutrition was food.”The official, he said, “shut up and went back to Washington.”Dr. Geiger in 1966 with Dr. John Hatch during construction of a community health center in Mound Bayou, Miss. They, along with Dr. Gibson, secured government grants and a sponsorship from Tufts University to bring more social services to the area.Credit…Jack Geiger, via Associated PressDr. Geiger helped found Physicians for Social Responsibility in 1961. The group argued that official predictions of the effects of nuclear war minimized the number of casualties and the extent of the destruction it would cause. At the group’s public meetings, Dr. Geiger’s job was “the bombing run” — offering a detailed account of what a one-megaton nuclear bomb would do to the city in which the meeting was being held.He had a resonant voice and a crisp, forceful delivery. His presentations left audiences stunned, according to a colleague in the group, Dr. Ira Helfand.Dr. Geiger was a co-author of one of the first articles to look at the medical costs of nuclear war. The article, in The New England Journal of Medicine, predicted the fate of Boston in a nuclear strike — 2 million dead, a half-million injured and fewer than 10,000 hospital beds left in the entire state of Massachusetts. Doctors must “explore a new area of preventive medicine, the prevention of thermonuclear war,” the article said.It was published in May 1962 — five months before the Cuban missile crisis, which took the United States and the Soviet Union to the brink of nuclear war.Dr. Geiger’s marriage in 1951 to Mary Battle, an administrator and executive assistant in health care, ended in divorce in 1968. They had no children. (Ms. Battle died in a car accident in 1977.) In 1982, he married Nicole Schupf, a neuroscientist, epidemiologist and professor at Columbia University.In addition to his wife and his stepson, Mr. Smith, Mr. Geiger is survived by two stepgrandsons. An older sister, Ruth Ann, a schoolteacher, died in 1986.In 1978, Dr. Geiger became a professor of community medicine at the City University of New York Medical School at City College of New York.In his final years, which were marked by bladder cancer, lung cancer and blindness from glaucoma, he continued to write book chapters, articles and editorials and to give talks.To the end he was an impassioned advocate for civil rights. In an essay published in 2016 by Physicians for Human Rights, he called for more action to fight the lead-poisoning of the water supply in Flint, Mich., and to hold accountable the officials responsible for it.With characteristic bluntness, he ascribed the contamination to “a contemptuous disregard for the health of people of color, especially if they are poor.”Alex Traub contributed reporting.AdvertisementContinue reading the main story More
