Books like the man who solved the market: how jim simons launched the quant revolution

James Harris Simons (; born 25 April 1938) is an American mathematician, billionaire hedge fund manager, and philanthropist. He is the founder of Renaissance Technologies, a 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". As reported by Forbes, his net worth is estimated to be $23.5 billion, making him the 24th-richest person in the United States.

Outside of finance, 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.
