Early Life And Education

Harry Markowitz, born on August 24, 1927, in Chicago, Illinois, was the son of Morris and Mildred Markowitz. His parents owned a small grocery store, and he was their only child. During his high school years, Markowitz developed a keen interest in physics and philosophy, particularly influenced by the ideas of David Hume. This interest carried over into his undergraduate studies at the University of Chicago, where he initially pursued a liberal arts education. He completed his Ph.B. in Liberal Arts in 1947, and inspired by his burgeoning interest in economics, he continued his education at the same institution. Under the tutelage of notable economists such as Milton Friedman, Tjalling Koopmans, Jacob Marschak, and Leonard Savage, Markowitz decided to specialize in economics. His academic journey at the University of Chicago culminated with an A.M. in Economics in 1950 and a Ph.D. in 1954. It was during his time as a student that he became a member of the Cowles Commission for Research in Economics, which significantly shaped his future contributions to financial economics.

His seminal contribution to economics came with the development of modern portfolio theory, which introduced critical concepts of asset risk, return, correlation, and diversification in investment portfolio returns. This work earned him the prestigious John von Neumann Theory Prize in 1989. The following year, Markowitz’s contributions were further recognized when he was awarded the Nobel Memorial Prize in Economic Sciences, sharing the honor with Merton H. Miller and William F. Sharpe for their collective work in financial economics. Markowitz’s academic journey included notable tenures at institutions like the RAND Corporation and Baruch College, and his influence extended beyond academia through his development of the SIMSCRIPT programming language. His legacy continues to shape the strategies of investors and the theoretical underpinnings of financial economics.
