David Mitchell Magerman (born 1968) is an American computer scientist and philanthropist. He spent several decades working for an investment management company and hedge fund.

Early life and education[edit]

Magerman was born to Melvin and Sheila Magerman. His father owned All-City Taxi in Miami, Florida, and his mother was a secretary for a group of accounting firms in Tamarac.[1]

Magerman received his Ph.D. degree from Stanford University in computer science.[2] He also received his B.S. from the University of Pennsylvania.[3]


Magerman spent two decades working for Robert Mercer’s New York-based investment management company Renaissance Technologies, where he developed trading algorithms.[4] In 2017, Magerman publicly opposed the views of his boss, Robert Mercer, concerning politics and race issues in America. Mercer, the co-CEO of Renaissance Technology, suspended Magerman without pay and later made the suspension permanent. Magerman filed a federal lawsuit against Mercer, seeking an excess of $150,000 in damages over alleged racist comments and unlawful termination.[5][4]

Business ventures[edit]

In order to maintain the Jewish community in his neighborhood, Magerman has worked on several business ventures. His first of these was Citron and Rose, an upscale kosher certified meat restaurant, with Michael Solomonov as the head chef. After seeing little to no benefit of an upscale dining experience, Magerman re-branded the establishment as C&R Kitchen, and split with head chef Solomonov.[6] During this time, he opened a casual dairy restaurant across the street. To better serve the community, C&R Kitchen was closed and replaced with a more fast casual place, The Dairy Express, known for its high capacity pizza oven. Currently[year missing] under construction is C&R Tavern, a mix between a kosher grocery store and a dining establishment.[7]


Through founding The Kohelet Foundation, Magerman has donated tens of millions of dollars to local causes.[citation needed] Some of these include Kohelet Yeshiva High School (renamed from Stern Hebrew High School in the gift's honor), Yeshiva University and the Yeshiva Lab School.

Freedom from Facebook[edit]

Magerman provided the initial funds for the campaign group "Freedom from Facebook", donating $425,000 as of late 2018.[8]

Personal life[edit]

Magerman married Debra Magerman (née Kampel), on 8 August 1999. They have four children.[1]
