Biography
Lloyd Stowell Shapley was born on June 2, 1923, in Cambridge, Massachusetts, into a family well-known for academic achievements. His father, Harlow Shapley, was a famous astronomer who led the Harvard College Observatory and significantly advanced understanding of the Milky Way galaxy. Growing up in this environment greatly influenced Lloyd's approach to science and mathematics.
He attended Phillips Exeter Academy before starting his undergraduate studies at Harvard University. World War II interrupted his academics, and he served in the United States Army Air Forces from 1943 to 1946, receiving the Bronze Star Medal in 1944 for his service. After the war, he returned to Harvard to complete his bachelor's degree, then went on to Princeton University for his graduate studies, where he earned his Ph.D. in mathematics in 1953 under the guidance of Albert W. Tucker.
Shapley spent most of his career at the RAND Corporation from 1954 to 1981 and later at the University of California, Los Angeles, where he was a professor in mathematics and economics. He had a major impact on game theory, building on the work of John von Neumann and Oskar Morgenstern. He developed key concepts like the Shapley value, a solution in cooperative game theory for fairly dividing gains among participants. His work with other mathematicians and economists brought about new insights in matching theory and market design.
In 2012, Shapley received the Nobel Memorial Prize in Economic Sciences, sharing it with Alvin E. Roth. The prize honored their innovative work on stable allocations and market design, which have been applied in real-world areas like medical residency matching programs and kidney exchange systems. Shapley's contributions gave a mathematical basis for creating stable, efficient matching systems in different economic settings. He passed away on March 12, 2016, in Tucson, Arizona, leaving behind a significant impact in both mathematics and economics.
Before Fame
Growing up with his father, astronomer Harlow Shapley, Lloyd was introduced to scientific thinking at an early age. Their home in Cambridge often had visits from well-known scientists and mathematicians, fostering an environment where intellectual curiosity was encouraged. At Phillips Exeter Academy, he received a strong education in classical mathematics and logical reasoning.
After World War II, there was significant growth in mathematical research, especially in areas like operations research and game theory. Shapley attended graduate school at Princeton during a time of great mathematical innovation, with figures like John von Neumann, Albert Einstein, and Alan Turing present at the university. This atmosphere of mathematical brilliance, along with the practical problem-solving needs that arose from wartime research, provided the ideal setting for developing the theoretical frameworks that marked his career.
Key Achievements
- Developed the Shapley value, a fundamental solution concept in cooperative game theory
- Co-created stable matching theory with David Gale, forming the basis for modern market design
- Won the 2012 Nobel Memorial Prize in Economic Sciences for work on stable allocations and market design
- Received the John von Neumann Theory Prize in 1981 for contributions to game theory
- Pioneered applications of game theory to economics, political science, and computer science
Did You Know?
- 01.His father Harlow Shapley was the astronomer who first determined that Earth was not at the center of the Milky Way galaxy
