Henry B. Laufer (born 1945) is an American mathematician, investor and philanthropist. He served as the Vice President of Research at Renaissance Technologies.

Early life[edit]

Henry B. Laufer was born in 1945.[2] He received his PhD from Princeton University in 1965, studying with Robert Gunning.


Laufer joined the mathematics department at the State University of New York at Stony Brook as a faculty member in 1971. His research focused on complex variables and algebraic topology. He left Stony Brook in 1992 to join Renaissance Technologies.[3] In 2015, a conference was held for his 70th anniversary at Tsinghua University in China.[2]

Laufer co-founded Medallion with billionaire Jim Simons in 1988.[4] Laufer served as chief scientist and vice president of research at Renaissance Technologies, its parent company.[5] He now serves on its board of directors.[5]

Laufer earned US$125,000,000 in 2008, despite the financial crisis of 2007–2008.[6] The following year, in 2009, he was named one of "Wall Street's Highest Earners" by Forbes, with an income of US$390,000,000.[7]

Philanthropy and political contributions[edit]

Laufer and his wife enabled the foundation of the Louis and Beatrice Laufer Center for Physical and Quantitative Biology at Stony Brook University with a donation in 2008.[8][9]

Laufer donated US$500,000 to Correct the Record, a political action committee which supported Hillary Clinton's 2016 presidential campaign, in February 2016.[10] Meanwhile, in April 2016, Laufer and his wife organized a US$500-ticket fundraiser for Clinton in Florida.[11][12] However, the fundraiser could only be attended by supporters who donated US$10,000 or more to Clinton during the Democratic Party primary.[11]

Personal life[edit]

Laufer is married to Dr. Marsha Zlatin Laufer, a speech-language pathologist, philanthropist and political activist.[13][14] She served as the chairwoman of the Democratic Party for the town of Brookhaven, New York from 2005 to 2009.[15][16] The couple resides in Manalapan, Florida.[11]
