James Harris Simons (April 25, 1938 – May 10, 2024) was an American hedge fund manager, investor, mathematician, and philanthropist.[4] At the time of his death, Simons' net worth was estimated to be $31.4 billion, making him the 55th-richest person in the world.[4] He was the founder of Renaissance Technologies, a quantitative hedge fund based in East Setauket, New York. He and his fund are known to be quantitative investors, using mathematical models and algorithms to make investment gains from market inefficiencies. Due to the long-term aggregate investment returns of Renaissance and its Medallion Fund, Simons was described as the "greatest investor on Wall Street", and more specifically "the most successful hedge fund manager of all time".[5][6][7]
Simons was known for his studies on pattern recognition.[8] He developed the Chern–Simons form (with Shiing-Shen Chern), and contributed to the development of string theory by providing a theoretical framework to combine geometry and topology with quantum field theory.[9]
In 1994, Simons and his wife, Marilyn, founded the Simons Foundation to support research in mathematics and fundamental sciences. The foundation is the top benefactor of Stony Brook University, Marilyn's alma mater, and is a major contributor to his alma maters, the Massachusetts Institute of Technology and the University of California, Berkeley. Simons was a member of the boards of the Stony Brook Foundation, the MIT Corporation, and the Simons Laufer Mathematical Sciences Institute in Berkeley, as well as chair of boards of Math for America, the Simons Foundation, and Renaissance Technologies.[10][11] In 2023, the Simons Foundation gave $500 million to Stony Brook University, the second-largest donation to a public university in American history.[12] In 2016, the International Astronomical Union named asteroid 6618 Jimsimons, which Clyde Tombaugh discovered in 1936, after Simons in honor of his contributions to mathematics and philanthropy.[13]
