Richard Herman Driehaus (born 1942 in Chicago) is a fund manager, businessman and philanthropist. He is the founder and chairman of Driehaus Capital Management LLC, 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, 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. The first recipient, for 2003, was Leon Krier, Demetri Porphyrios in 2004, Quinlan Terry in 2005, Allan Greenberg in 2006, Jaquelin T. Robertson in 2007, the husband-wife architect and urbanist team of Andres Duany and Elizabeth Plater-Zyberk in 2008, Abdel-Wahed El-Wakil in 2009, Rafael Manzano Martos in 2010, Robert A.M. Stern in 2011, Michael Graves in 2012 and Thomas H. Beeby in 2013.
Since 2012 a new architectural 50,000€ prize is awarded by him to a leading architect working in architectural heritage restoration in Spain whose work particularly embodies the values of classical and traditional Spanish architecture: the Rafael Manzano Martos Prize. The first recipient was Leopoldo Gil Cornet in 2012 for his decades-lasting restoration works in the Real Colegiata of Roncesvalles (Navarre, Spain).
