He is the founder of Renaissance Technologies, a quantitative hedge fund based in Setauket-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 is described as the “greatest investor on Wall Street,” and more specifically “the most successful hedge fund manager of all time.”
As reported by Simons’ net worth is estimated to be $24.6 billion, making him the 23rd-richest person in the United States.
Simons is known for his studies on pattern recognition. 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. In 1994, Simons founded the Simons Foundation with his wife to support researches in mathematics and fundamental sciences. He is one of the biggest donors to the University of California, Berkeley, establishing the Simons Institute for the Theory of Computing in 2012, and to Berkeley’s Mathematical Sciences Research Institute, where he serves as a member of the Board of Trustees.
