Henry and Marsha Laufer

NET WORTH: $2 billion

SOURCE OF WEALTH: Renaissance Technologies 

FUNDING AREAS: Education & Science Research

OVERVIEW: Henry Laufer and his wife Marsha have made several sizable donations to educational institutions. They do not appear to have a formal family foundation. 

BACKGROUND: Henry Laufer graduated from City College of New York in 1964 and earned MA and Ph.D. degrees in mathematics from Princeton University. He taught at MIT and Princeton and joined the Mathematics Department of Stony Brook in 1971 where he worked for more than two decades. Laufer joined Renaissance Technologies in 1992, where he was chief scientist and vice president of research. He retired from the hedge fund firm in 2009.

ISSUES:

EDUCATION & SCIENCE RESEARCH: Henry and Marsha helped create Stony Brook University's Laufer Center for Physical and Quantitative Biology, named after Laufer’s parents. Laufer is on the board of Stony Brook Foundation. The couple has also supported scholarships at the school. Support has gone to The National Museum of Mathematics (MoMath). 

OTHER: Giving has encompassed women's rights, political advocacy, healthcare, arts, and Jewish causes. Grants have gone to Long Island Museum of American Art and the Suffolk County Center on Holocaust, Diversity, and Human Understanding. The couple are major Democratic donors and Marsha served as the chairwoman of the Democratic Party in Brookhaven, New York.

LOOKING FORWARD: Given the lack of a formal foundation, it's possible some important gifts may be missing from this rundown.
