Richard H. Driehaus (born 1942 in Chicago) is a fund manager, businessman and philanthropist. He is the founder and chairman of Driehaus_capital_management, based in Chicago, a firm which manages US$10 billion. In the year 2000, he was named Barron's "All-Century" team of the 25 individuals who have been the most influential within the mutual fund industry over the past 100 years.
From 1968 through 1973, he developed research ideas for the Institutional Trading department at A.G. Becker & Co. In 1973, he became Director of Research for Mullaney, Wells & Co. In 1976, he became Director of Research and a money manager for Jesup & Lamont. He founded Driehaus Securities LLC in 1980, followed by Driehaus Capital Management LLC in 1982, Driehaus Mutual Funds in 1996, and Driehaus Capital Management (USVI) LLC in 1997.
Driehaus has contributed a total $92 million in today's dollars since 1984. His foundation intends to continue to distribute a minimum of $4 million a year, mostly in Chicago. Originally, Mr. Driehaus says, his plan was to give away only $100 million during his lifetime. But he now believes that he will end up parting with more than twice that amount.
In addition to other philanthropic pursuits, the $200,000 Richard H. Driehaus Prize for Classical Architecture was established in 2003 and is presented annually through the University of Notre Dame School of Architecture to honor a major contributor in the field of traditional and classical architecture.
