Dr. Guy Alexandre (1934-2024), gave birth to brain death in deceased organ transplantation

 The father of brain death has died.

Here's the NYT obit.

Guy Alexandre, Transplant Surgeon Who Redefined Death, Dies at 89. His willingness to remove kidneys from brain-dead patients increased the organs’ viability while challenging the line between living and dead.  By Clay Risen

"Guy Alexandre, a Belgian transplant surgeon who in the 1960s risked professional censure by removing kidneys from brain-dead patients whose hearts were still beating — a procedure that greatly improved organ viability while challenging the medical definition of death itself — died on Feb. 14 at his home in Brussels. He was 89.

...

"Dr. Alexandre was just 29 and fresh off a yearlong fellowship at Harvard Medical School when, in June 1963, a young patient was wheeled into the hospital where he worked in Louvain, Belgium. She had sustained a traumatic head injury in a traffic accident, and despite extensive neurosurgery, doctors pronounced her brain dead, though her heart continued to beat.

"He knew that in another part of the hospital, a patient was suffering from renal failure. He had assisted on kidney transplants at Harvard, and he understood that the organs began to lose viability soon after the heart stops beating.

"Dr. Alexandre pulled the chief surgeon, Jean Morelle, aside and made his case. Brain death, he said, is death. Machines can keep a heart beating for a long time with no hope of reviving a patient. His argument went against centuries of assumptions about the line between life and death, but Dr. Morelle was persuaded.

...

"Over the next two years, Dr. Alexandre and Dr. Morelle quietly performed several more kidney transplants using the same procedure. Finally, at a medical conference in London in 1965, Dr. Alexandre announced what he had been doing.

...

"In 1968, the Harvard Ad Hoc Committee, a group of medical experts, largely adopted Dr. Alexandre’s criteria when it declared that an irreversible coma should be understood as the equivalent of death, whether the heart continues to beat or not.

"Today, Dr. Alexandre’s perspective is widely shared in the medical community, and removing organs from brain-dead patients has become an accepted practice.

“The greatness of Alexandre’s insight was that he was able to see the insignificance of the beating heart,” Robert Berman, an organ-donation activist and journalist, wrote in Tablet magazine in 2019.

And here's the story from Tablet magazine, interesting in a number of respects:

The Man Who Remade Death. Guy Alexandre was the first surgeon to remove organs from a patient with a beating heart. His colleagues thought him a murderer; Alexandre disagreed and revolutionized our understanding of death.  BY ROBBY BERMAN, Feb 4, 2019

"I met Alexandre a few months ago in his home in an upscale suburb of Brussels. The octogenarian is charming, affable and avuncular but he does not mince words: The physicians who accused him of murder “were hypocrites. They viewed their brain dead patients as alive yet they had no qualms about turning off the ventilator to get the heart to stop beating before they removed kidneys. In addition to ‘killing’ the patient, they were giving the recipients damaged kidneys that suffered ischemia … oxygen deprivation. The kidneys did not work well; they did not last long.”

"Given that brain death was not well known by the public in 1963, I asked Alexandre how he succeeded in getting consent from families to donate the organs. “It was simple. I didn’t ask. I told the families the situation was grim and I removed the organs in the middle of the night. When the family returned the next morning I told them their loved one had died during the night.”

"In 1961, Alexandre was in his third year of surgical training. He left Brussels for Boston to attend Harvard Medical School where he studied under professor Joseph Murray, the surgeon famous for performing the first successful kidney transplant between twins in 1954. After Alexandre successfully executed a number of kidney transplants between dogs in the laboratory, he was invited by Murray to join him in the operating room to operate on humans. It was there that Alexandre noticed a curious phenomenon.

"Murray turned off the ventilator in order to cause the heart to stop beating and only then did he extract the organs. Alexandre felt there was no need to damage the kidneys by depriving them of oxygen. He believed when looking at a human body with a dead brain that he was looking at a corpse that was suffering from a bizarre medical condition: a beating heart. In other words, the organism was dead but the organs remained alive."

Who Shall Live? (3rd edition) by Victor R. Fuchs and Karen Eggleston

Shortly before he passed away in September at the age of 99, Vic Fuchs finished the third edition of his book Who Shall Live?, now with a coauthor, Karen Eggleston.

It just came out now, in time for his 100th birthday next month.

Memorial service for Vic Fuchs

 Yesterday, at Etz Chayim Synagogue,  Palo Alto.


Here is my brief eulogy:

Vic was the patriarch of a clan, and a man of wide and old friendships. He was, by the way, also a brilliant, erudite, compassionate economist.

Emilie and I were among his new friends. In 2013 we bought a house down the hill from Vic, and held an open house; he came over, carrying his own chair-back, and was the life of the party.  In those days he used to reply to questions about how he was doing with a joke: “I’m in perfect health—my psychiatrist says it’s all in my body.”

That joke got less funny as his body continued to betray him, and after a while he stopped telling it.

When he joined us for dinner, he and Emilie would negotiate the menu. (He was a fussy eater, who liked his food very plain).

In 2016, when Vic joined us to watch one of the debates among Democratic primary candidates for president, he couldn’t contain himself when they discussed health care, and I gave him a lift home before the debate concluded, so he could write an op-ed. He was still in the game.

During Covid, he stopped leaving his house except to go to the doctor. As his mobility declined, our visits migrated from his patio, to the downstairs living room, and eventually up the half flight of stairs to his office.

Vic’s mind remained sharp. We were able to visit him until about a month before he passed away. He was worried about the world, but still eager to hear jokes, and to tell them.

He was a role model, and a pleasure to spend time with.  

Vic was a man of many parts, and his life was full of accomplishments, admirers, family and friends for whom his memory will be a blessing.

Vic Fuchs (1924-2023)

My friend and neighbor Vic Fuchs, the dean of American health economists, passed away on Friday.  

He was just a few months short of 100, but in the last year he finished revising the third edition of his 1975 book,  Who Shall Live? Health, Economics, and Social Choice.

He bravely bore some physical ailments, but his mind remained sharp, and he was always a pleasure to talk to. (He used to joke "I'm in perfect health: my psychiatrist says its all in my body.")

He kept abreast of current events, and remained informed and concerned about the state of the health care system in the U.S., and democracy.

Fuchs’ influence and tireless devotion to the field of health care economics and the Stanford community spanned decades.

Lloyd Shapley (1923-2016) Centennial

 Lloyd Harlow Shapley was born in 1923: he would be (and I guess is) 100 years old this year.  His family is assembling a website honoring his centennial. (It's part of a family of web pages devoted to the life and work of Lloyd's dad, the astronomer Harlow Shapley.)

Here's the page for the Lloyd Shapley Centennial

It appears to be a work in progress, with many links. It begins this way:

"Lloyd Shapley (1923-2016) was a Nobel prizewinning mathematician. Shapley’s "intellectual life and career ... was among the most fertile of the 20th century." For the Centennial of Lloyd’s birth the Harlow Shapley Project offers this easy-access guide to Lloyd's WORK, his favorite GAME Kriegspiel, personal STORIES not published before and his four PRIZES.

"Lloyd Shapley was one of the founding giants of game theory. He shared the 2012 Nobel Prize in Economics for his seminal work with the late David Gale on stable matching – situations in which there are no two agents who would prefer one another over their current counterparts. But "he could have won a Nobel for any of a number of his papers that initiated whole literatures,” wrote Alvin E. Roth, Lloyd’s Nobel co-winner (right).

"Mathematical giant John von Neumann (right) invited Lloyd to leave RAND for Princeton on the basis of a two-page paper Lloyd sent him. After getting his Princeton PhD Lloyd returned to RAND full-time. He was a very productive member of the fabled Mathematics Division. Lloyd was almost unbeatable in the Division’s lunchtime Kriegspiel matches. 

"The Work page has summaries of Lloyd’s main contributions prepared by Dr. Bruce E. Krell, a game theorist who was a colleague of Lloyd’s at RAND. The Work page also offers a bibliography of selected descriptions of his work. The Work includes the 1962 “marriage problem” paper with David Gale (right), which won the Nobel."

Harry Markowitz (1927-2023)

 Harry Markowitz, who invented modern portfolio theory, and did much beside, has died.

Here's his NYT obituary, which was apparently prepared long in advance.

Harry Markowitz, Nobel-Winning Pioneer of Modern Portfolio Theory, Dies at 95. He overturned the traditional approach to buying stocks by examining the relationship between risk and reward. By Robert D. Hershey Jr.

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."

********

PORTFOLIO SELECTION, by Harry Markowitz, The Journal of Finance Volume 7, Issue 1 p. 77-91 First published: March 1952  https://doi.org/10.1111/j.1540-6261.1952.tb01525.x

*******

Here's the beginning of the 1990 Nobel Prize press release:

16 October 1990

THIS YEAR’S LAUREATES ARE PIONEERS IN THE THEORY OF FINANCIAL ECONOMICS AND CORPORATE FINANCE

The Royal Swedish Academy of Sciences has decided to award the 1990 Alfred Nobel Memorial Prize in Economic Sciences with one third each, to

Professor Harry Markowitz, City University of New York, USA,
Professor Merton Miller, University of Chicago, USA,
Professor William Sharpe, Stanford University, USA,

for their pioneering work in the theory of financial economics.

Harry Markowitz is awarded the Prize for having developed the theory of portfolio choice;
William Sharpe, for his contributions to the theory of price formation for financial assets, the so-called, Capital Asset Pricing Model (CAPM); and
Merton Miller, for his fundamental contributions to the theory of corporate finance.

********

Here's the citation for the 1989 von Neumann theory prize in operations research:

"1989 John von Neumann Theory Prize:  


"Harry M. Markowitz received the 1989 John von Neumann Theory Prize. Dr. Markowitz, presenter Ellis Johnson noted, contributed ground-breaking work in three areas: portfolio selection, mathematical programming, and simulation.


"Harry Markowitz is the Marvin Speiser Distinguished Professor of Finance and Economics at Baruch College, NYC. He developed the portfolio selection model in his Ph.D. thesis at the University of Chicago. First published in 1952, today his model is one of the most widely used quantitative tools for investment analysis.


"During the late 50s Markowitz worked on mathematical programming at the RAND Corp. and also did his ground-breaking work on factoring bases and maintaining sparsity in the course of solving linear programs, in effect introducing the triangularization or LU factorization in place of inversion of the basis. His selection criterion for reducing fill-in when forming basis factors is the well-known Markowitz criterion and is still used in state-of-the-art codes for both LU and Cholesky factorizations. Markowitz's third main area of activity involved codifying the underlying notions of simulation by defining a world view composed of entities having attributes and belonging to sets that have defined relationships with each other. The state of the world changes through events, which are triggered by time. Based on this, in the 60s he developed a high-level simulation language, SIMSCRIPT, and in the 80s has collaborated with IBM researchers to develop EAS-E, an integrated data base, modeling and applications development language.


Dr. Markowitz told OR/MS Today that the award was a great honor and a reflection of the influence of von Neumann on portfolio theory."

Victor Elias (1937-2023)

Victor Elias died last week, at 85.  He had a strong influence on academic economics in Argentina, not least through the many influential Argentine economists he helped inspire to study in the U.S., particularly at the University of Chicago, where he got his Ph.D. in 1969.

Here's the funeral notice published yesterday in La Nacion:

"Victor Elias, RIP. It is with deep regret that we bid farewell to a great talent and person, with countless  disciples, admirers and friends, economists scattered throughout the world. We accompany the entire community of Tucuman economists, the UNT and especially his children, grandchildren and great-grandson. Signed by: Fernando Alvarez, Hugo Hopenhayn, Rody Manuelli, Juan Pablo Nicolini, Alvin Roth, Silvana Tenreyro, Iván Werning."

Here's the obit from La Gaceta

Murió el economista tucumano Víctor Elías. Tuvo una reconocida trayectoria como académico en la UNT. Tenía 85 años.[Tucuman economist Víctor Elías died. He had a recognized career as an academic at UNT. He was 85 years old.]

"The renowned Tucuman economist and academic Víctor Elías passed away at the age of 85, leaving an enormous legacy that has marked several generations of Tucumans who studied Economics at the National University of Tucumán. 

"The son of Syrian immigrants, he was born in the capital of Tucumán on July 21, 1937 and due to his ancestry he received the nickname "Turk", as he was known inside and outside academic circles. "

Tonya Ingram (1991-2022), health activist, died while waiting for a kidney

 Tonya Ingram, a poet and health activist who testified in Congress about the long waiting list for kidney transplants, died last month while still waiting.  Saturday's New York Times had a moving column about her activism, her struggle and her long wait.

Paul David (1935-2023)

 My Stanford colleague Paul David has died. He was an exceptional, iconic economic historian.

Gavin Wright has written this obit:

Professor Paul David died at the age of 87

"Always an economic historian, Paul soon extended his horizons in diverse and seemingly disparate ways.  He became a strong advocate of the view that historical research should be fundamental to the economics discipline; in brief; “history matters.”  The essence of the argument was captured by Paul’s incisive account of the persistence of the QWERTY typewriter keyboard despite its technical disadvantages, one of the most cited articles in all of economics (AER 1985).  “History Matters” is the title of a festschrift presented by a group of Paul’s former students in 2004, in which the editors write: “No scholar has more forcefully and influentially argued the case for making economics a truly historical social science – one that, like evolutionary biology, gives past events a central role in understanding the present.” 

"A continuing focus throughout Paul’s career was the diffusion of new technologies.  An important early paper considered the adoption of the mechanical reaper in the American Midwest.  Invention occurred in the 1830s, yet the first wave of adoption occurred only in the 1850s.  The twenty-year delay, according to Paul, was explained by the fact that a minimum scale was required to cover the fixed costs of purchasing the reaper.  Only when farms size passed this “threshold” did mechanization make economic sense.  Specialists have debated the specifics ever since, but the basic form of Paul’s diffusion model has been highly influential.  In many respects it formalized the accounts of delayed diffusion presented by our late colleague Nate Rosenberg, and thus became something of a “Stanford school” of thought in this area.  Scrolling forward to 1990, the era of the “Solow paradox,” Paul offered an analogy between the delayed productivity effects of computer technology and a similar lag in the impact of electrification between the 1880s and the 1920s.  With the IT-driven productivity surge of the late 1990s, this article also attained iconic status (AER 1990)."

Amnon Rapoport (1936-2022)

 Amnon Rapoport, a pioneer of experimental game theory, has died. 

Here's a brief obituary:

Amnon Rapoport, Distinguished Professor Emeritus of Management and Organizations at the University of Arizona, passed away on December 6th

I don't find his date of birth on the web, but in August of 1996 I participated in a conference in honor of his 60th birthday, at the University of North Carolina at Chapel Hill, where he had both studied and taught in the Department of Psychology.  Amnon had already had several heart attacks by then, and his students, who loved him, thought it prudent to have a celebration of his work at that relatively young age, but that caution proved unnecessary. 

Here's the volume of papers presented at that conference, edited by three of his students:

Budescu, David V., Ido Erev, and Rami Zwick, eds. Games and human behavior: Essays in honor of Amnon Rapoport. Erlbaum, 1999.

I first learned of his work when, as a grad student, I took a course in game theory taught by Michael Maschler, who told us about Amnon's experiments on the bargaining set.

He was a man ahead of his time, and maybe situated in the wrong discipline.  It seemed to him natural that psychologists should take a leading role in the experimental study of game theory, and he noted with some regret that instead that literature had been ceded to economists. Here's a paragraph from the introduction to 

Rapoport, Amnon. Experimental studies of interactive decisions. Vol. 5. Springer Science & Business Media, 2012.

"The history of experimentation in psychology is rich and old. It would have been quite natural and highly desirable for psychologists to extend their scope of research and assume a major role in the study of economic decision behavior. Psychology professes to be the general study of human behavior. Most psychologists are trained to regard their discipline as an observational science; they do not have to overcome the conditioning of many economists who think of economics as an a priori science. Psychologists' knowledge of experimental techniques is comprehensive. and their experience in conducting experiments. analyzing data. and discovering empirical regularities exceeds that of most economists. However. with the exception of research on individual choice behavior - where psychologists like Tversky, Kahneman, and Slovic have played a major role - psychologists have not contributed in any significant way to the growing research in experimental economics. Social psychologists for whom interactive behavior is the core of their discipline, have virtually abandoned the study of economic decisions in small groups to their colleagues in economics and related disciplines. "

Here's his cv as of 2017, and his google scholar page.

**********

Update: here's an email that Rami Zwick sent to the Economic Science Association (ESA):

"Dear ESA community,

It is with great sadness that we announce the passing of our teacher, mentor, colleague, co-author and friend, Professor Amnon Rapoport, in Tucson Arizona on December 6, 2022. 

Professor Rapoport served on the faculty of the University of California, Riverside School of Business; University of Arizona; UNC Chapel Hill; University of Haifa, Israel; and the Hebrew University of Jerusalem, Israel. He earned his Bachelor of Arts degree in psychology and philosophy from the Hebrew University of Jerusalem, then went on to earn his M.A. and Ph.D. in quantitative psychology at UNC Chapel Hill. 

Professor Rapoport was one of the pioneers and leaders in the experimental study and quantitative modeling of human decisions in social and interactive contexts. During his distinguished career, he published four books (and edited others) and more than 300 research papers and chapters in leading psychological, management, operation, marketing, decision theory, economics, and political science journals, and is recognized as a leading authority in many of these areas. His most important and influential work was on experimental studies of interactive decision-making behavior. This includes theoretical and empirical research on: 

Coalition formation 

Bargaining 

Social dilemmas 

Behavioral operations management 

Behavioral game theory 

Dynamic pricing 

Directed networks 

 Professor Rapoport’s work was theory-driven, and, in most cases, the theory was represented formally by mathematical (primarily, but not exclusively, game theoretical) models. At the same time, he was a meticulous and rigorous, yet imaginative and creative experimentalist. In fact, he was one of the pioneers of computerized experimentation in the domain of individual and group decision making. 

With a career spanning over 60 years, Professor Rapoport nurtured and supported the careers of generations of scholars and researchers. He will be greatly missed by his family, friends, colleagues, co-authors, and students."

Jacques Drèze (1929-2022)

Jacques Drèze, the eminent Belgian economist who was the founding director of the Center for Operations Research and Econometrics (CORE) at UCLouvain has died.

Aside from his considerable professional contributions as a researcher, he was an institution builder.  CORE was a center of game theory when game theory was young, and played an important role in its development.


Here is the Econometric Society memorium: IN MEMORIAM: Jacques Drèze

"CORE and its prestigious visitors’ program, thanks initially to the support from the Ford foundation, was his initiative as well as the European Doctoral Program in Quantitative Economics(EDP)."

Elizabeth "Betsy" E. Bailey (1939-2022)

 Betsey Bailey, an economist of many parts, has passed away.

I knew of her both as an academic dean at CMU and as a proponent of airline deregulation, in theory and practice.  The theory had to do with the idea that even markets with big players who had lots of market share might be perfectly competitive (and hence not need lots of regulation) if they were "contestable," i.e. if new entrants could enter the market at low cost if they saw profitable opportunities.  The idea was that the airline market would keep prices low to ward off new entrants, or entry by competitors into profitable routes.  Her stint on the Civil Aviation Board led to much reduced regulation of commercial airlines, after which airlines adopted the 'hub and spoke' patterns we see today. (When they were regulated, airline routes looked more like railroads, e.g. some had northern routes, some southern...)

Here's the Washington Post obituary:

Elizabeth Bailey, pathbreaker for women in economics, dies at 83. She was the first woman to receive a PhD in economics from Princeton and helped deregulate airlines as the first woman on the Civil Aeronautics Board  By Emily Langer

"Dr. Bailey, 83, who died Aug. 19 at her home in Reston, Va., was widely credited with opening opportunities for women in her field.

"In 1972, she became the first woman to receive a PhD in economics from Princeton University. Five years later, President Jimmy Carter appointed her the first female member of the Civil Aeronautics Board, where she helped provide the intellectual framework for the deregulation of the airline industry.

...

"Later, at Carnegie Mellon University in Pittsburgh, Dr. Bailey became the first woman to serve as dean of a Top 10 graduate business school."

Same sex marriage in Colorado: then and now

In 1975, as the county clerk of Boulder County, Cela Rorex issued several marriage licenses to same sex couples, before the State Attorney General ruled against them.  When she died earlier this month, she was remembered by the current Colorado governor, and his husband.

Clela Rorex, Clerk Who Broke a Gay-Marriage Barrier, Dies at 78. In 1975 she issued a gay couple a license to marry in Colorado, becoming a hero to some and an object of hate for others.  By Neil Genzlinger

"Colorado’s governor, Jared Polis, who is gay, was among those paying tribute to Ms. Rorex.

“So many families, including First Gentleman Marlon Reis and I, are grateful for the visionary leadership of Clela Rorex,” he wrote on Facebook, calling her a woman “ahead of her time.”

David Schmeidler (1939-2022)

My old friend David Schmeidler has just passed away. 

We met very shortly after I got my Ph.D.in 1974 and moved to the University of Illinois, where he was a frequent visitor. He was already well known for his work on the nucleolus (a kind of cardinal centroid for games in characteristic function form with sidepayments, which is contained in the (ordinal) bargaining set). 

He was the very model of a modern major game theorist.  At the time we met, I remember being impressed by his breadth of interests, in connection e.g. with his paper with Elisha Pazner on fairness. I asked him how he viewed his work on fairness as connecting with his work on game theory, and as I recall he said something (briefly) to the effect that game theorists should be interested in all aspects of transactions.  I was impressed. (Decades later at dinner in our house in Boston, I told him that, and he replied "Later I decided that was all bullshit."  But I remained, and remain impressed.)

Here's a picture I took of him in 2014, speaking at a conference in Brazil organized by Marilda Sotomayor. 


David Schmeidler in Sao Paulo in 2014

He is probably best known today for his work on various models of non-expected utility theory. Here is David on Google Scholar.

 Here's a tribute to him published two years ago by Peter Wakker, who met him as a grad student in 1984, and recalls him as a man of few words, and big insights.

A Personal Tribute to David Schmeidler’s Influence by Peter P. Wakker Dans Revue économique 2020/2 (Vol. 71), pages 387 à 390

Some of his most important work is with Itzhak Gilboa, who speaks about their work here (video and transcript): Non-Bayesian Decision Theory

Itai Ashlagi recommends these of his papers:

Equilibrium points of nonatomic games,

The nucleolus of a characteristic function game

 Maxmin Expected Utility with a Non-Unique Prior,

Subjective probability and expected utility without additivity.

David Bennet Sr., who lived for two months with a transplanted pig heart, RIP

 Xenotransplants from pigs are probably here to stay, but are also not quite here yet, and may not be for some time.

Yesterday's NY Times has the story:

Patient in Groundbreaking Heart Transplant Dies. David Bennett Sr. had received a heart from a genetically modified pig, a procedure that may yet offer hope to millions of Americans needing transplants.  By Roni Caryn Rabin, March 9, 2022

"The first person to have his failing heart replaced with that of a genetically altered pig in a groundbreaking operation died Tuesday afternoon at the University of Maryland Medical Center, two months after the transplant surgery.

...

"Mr. Bennett’s transplant was initially deemed successful. It is still considered a significant step forward, because the pig’s heart was not immediately rejected and continued to function for well over a month, passing a critical milestone for transplant patients.

The Times story also made mention of the complicated discussion about organ donation, in this case having to do with the recipient's checkered history, as discussed in this earlier story from the Washington Post:
