Harry Max Markowitz (born August 24, 1927) has applied computer and mathematical techniques to various practical decision making areas.
In finance: he presented in an article in 1952 and a book in 1959 "modern portfolio theory," now a standard topic in college courses and widely used by institutional investors for tactical asset allocation, risk control, and attribution analysis.
In other areas: Dr. Markowitz developed "sparse matrix" techniques for solving very large mathematical optimization problems, now standard in production software for optimization programs.
He also designed and supervised the development of the SIMSCRIPT programming language which has been widely used for programming computer simulations of systems like factories, transportation systems, and communication networks.
In 1989 Dr. Markowitz received The John von Neumann Award from the Operations Research Society of America for his work in portfolio theory, sparse matrix techniques, and SIMSCRIPT.
In 1990 he shared The Nobel Prize in Economics for his work on portfolio theory.
