The company that would become CACI International is founded by Herb Karr and Harry Markowitz in 1962 as California Analysis Center, Inc.

Markowitz now divides his time between teaching (he is an adjunct professor at the Rady School of Management at the University of California at San Diego, UCSD), video casting lectures, and consulting (out of his Harry Markowitz Company offices).

Harry M. Markowitz shares the 1990 Nobel Prize in Economic Sciences with Merton H. Miller and William F. Sharpe "for their pioneering work in the theory of financial economics". Markowitz has constructed a micro theory of portfolio management for individual wealth holders.

He joins the RAND Corporation in 1952. He researches optimization techniques for stock-market portfolios.

Harry Markowitz is born in Chicago.

Markowitz chooses to apply mathematics to the analysis of the stock market as the topic for his dissertation. In 1955, he receives a PhD from the University of Chicago with a thesis on the portfolio theory. The topic is so novel that, while defending his dissertation, Milton Friedman argues that his contribution is not economics.

After working at IBM’s T.J. Watson Research Center from 1974 to 1983 he works at the City University of New York, when he is chosen for the Nobel Prize.

He takes the two-year Bachelor’s program at the University of Chicago. After that, he decides to study Economics.

Markowitz spends a year at the Cowles Foundation at the Yale University. 

In 1968, Markowitz joins Arbitrage Management company founded by Michael Goodkin. Working with Paul Samuelson and Robert Merton he creates a hedge fund that represents the first known attempt at computerized arbitrage trading. He takes over as chief executive in 1970. AMC is sold to Stuart & Co. in 1971. A year later, Markowitz leaves the company.
