1. Introduction

James Harris "Jim" Simons (/ˈsaɪmənz/; born April 25, 1938) is an American mathematician, billionaire hedge fund manager, and philanthropist. He is known as a quantitative investor and in 1982 founded Renaissance Technologies, a private hedge fund based in New York City . Although Simons retired from the fund in 2009, he remains its non-executive chairman and adviser.^[1]

He is also known for his studies on pattern recognition. He developed (with Shiing-Shen Chern) the Chern–Simons form,^[2] and contributed to the development of string theory by providing a theoretical framework to combine geometry and topology with quantum field theory.^[3] From 1968 to 1978,^[4] Simons was a mathematics professor and subsequent chair of the mathematics department at Stony Brook University.^[5]

As reported by Forbes, his net worth as of October 2018 is estimated to be $20 billion, while in the previous year, it was $15.5 billion.^[6]

In 2016, asteroid 6618 Jimsimons,^[7] discovered by Clyde Tombaugh in 1936, was named after Simons by the International Astronomical Union in honor of his contributions to mathematics and philanthropy.

2. Early Life and Education

James Harris Simons was born on April 25, 1938^[8][9] to an American Jewish family,^[10] the only child of Marcia (née Kantor)^[11] and Matthew Simons, and raised in Brookline, Massachusetts.^[12] His father owned a shoe factory.^[13]

He received a bachelor's degree in mathematics from the Massachusetts Institute of Technology in 1958^[14] and a PhD, also in mathematics, from the University of California, Berkeley, under supervision of Bertram Kostant in 1961, at the age of 23.^[14]

3. Academic and Scientific Career

Simons' mathematical work has primarily focused on the geometry and topology of manifolds. His 1962 Berkeley PhD thesis, written under the direction of Bertram Kostant, gave a new and more conceptual proof of Berger's classification of the holonomy groups of Riemannian manifolds, which is now a cornerstone of modern geometry. He subsequently began to work with Shing-Shen Chern on the theory of characteristic classes, eventually discovering the Chern–Simons secondary characteristic classes of 3-manifolds, which are deeply related to the Yang-Mills functional on 4-manifolds, and have had a profound effect on modern physics. These and other contributions to geometry and topology led to Simons becoming the 1976 recipient of the AMS Oswald Veblen Prize in Geometry. In 2014, he was elected to the National Academy of Sciences of the USA.^[15]

In 1964, Simons worked with the National Security Agency to break codes.^[16] Between 1964 and 1968, he was on the research staff of the Communications Research Division of the Institute for Defense Analyses (IDA) and taught mathematics at the Massachusetts Institute of Technology and Harvard University, ultimately joining the faculty at Stony Brook University. In 1968, he was appointed chairman of the math department at Stony Brook University.

Simons was asked by IBM in 1973 to attack the block cipher Lucifer, an early but direct precursor to the Data Encryption Standard (DES).^[17]

Simons founded Math for America, a nonprofit organization, in January 2004 with a mission to improve mathematics education in United States public schools by recruiting more highly qualified teachers. He funds a variety of research projects.

4. Investment Career

4.1. Renaissance Technologies

For more than two decades, Simons' Renaissance Technologies' hedge funds, which trade in markets around the world, have employed mathematical models to analyze and execute trades, many automated. Renaissance uses computer-based models to predict price changes in financial instruments. These models are based on analyzing as much data as can be gathered, then looking for non-random movements to make predictions.

Renaissance employs specialists with non-financial backgrounds, including mathematicians, physicists, signal processing experts and statisticians. The firm's latest fund is the Renaissance Institutional Equities Fund (RIEF).^[18] RIEF has historically trailed the firm's better-known Medallion fund, a separate fund that contains only the personal money of the firm's executives.^[19]

"It's startling to see such a highly successful mathematician achieve success in another field," says Edward Witten, professor of physics at the Institute for Advanced Study in Princeton, NJ, and considered by many of his peers to be the most accomplished theoretical physicist alive...^[20]

In 2006, Simons was named Financial Engineer of the Year by the International Association of Financial Engineers. In 2007, he was estimated to have personally earned $2.8 billion,^[21] $1.7 billion in 2006,^[22] $1.5 billion in 2005^[23] (the largest compensation among hedge fund managers that year),^[24] and $670 million in 2004.

5. Personal Life

Simons shuns the limelight and rarely gives interviews, citing Benjamin the Donkey in Animal Farm for explanation: "God gave me a tail to keep off the flies. But I'd rather have had no tail and no flies."^[25] On October 10, 2009, Simons announced he would retire on January 1, 2010 but remain at Renaissance as nonexecutive chairman.^[26]

In 1996, his son Paul, aged 34, was riding a bicycle, when he was killed by a car on Long Island.^[16] In 2003, his son Nicholas, aged 24, drowned on a trip to Bali, Indonesia. His son Nat Simons is an investor and philanthropist.^[27]

6. Political and Economic Views

Simons is a major contributor to Democratic Party political action committees. According to the Center for Responsive Politics, Simons is currently ranked the #5 donor to federal candidates in the 2016 election cycle, coming behind co-CEO Robert Mercer, who is ranked #1 and generally donates to Republicans.^[28] Simons has donated $7 million to Hillary Clinton's Priorities USA Action,^[29] $2.6 million to the House and Senate Majority PACs, and $500,000 to EMILY's List.^[28] He also donated $25,000 to Republican Senator Lindsey Graham's super PAC.^[28] Since 2006 Simons has contributed about $30.6 million to federal campaigns.^[28] Since 1990, Renaissance Technologies has contributed $59,081,152 to federal campaigns and since 2001, has spent $3,730,000 on lobbying.^[30]

7. Controversies

According to The Wall Street Journal in May 2009, Simons was questioned by investors on the dramatic performance gap of Renaissance Technologies' portfolios. The Medallion Fund, which has been available exclusively to current and past employees and their families, surged 80% in 2008 in spite of hefty fees; the Renaissance Institutional Equities Fund (RIEF), owned by outsiders, lost money in both 2008 and 2009; RIEF declined 16% in 2008.^[31]

On July 22, 2014, Simons was subject to bipartisan condemnation by the U.S. Senate Permanent Subcommittee on Investigations for the use of complex barrier options to shield day-to-day trading (usually subject to higher ordinary income tax rates) as long-term capital gains. "Renaissance Technologies was able to avoid paying more than $6 billion in taxes by disguising its day-to-day stock trades as long term investments," said Sen. John McCain (R., Ariz.), the committee's ranking Republican, in his opening statement.^[32]

An article published in The New York Times in 2015 said that Simons was involved in one of the biggest tax battles of the year, with Renaissance Technologies being "under review by the I.R.S. over a loophole that saved their fund an estimated $6.8 billion in taxes over roughly a decade."^[33]

8. Wealth and Philanthropy

He was named by the Financial Times in 2006 as "the world's smartest billionaire".^[34] According to Forbes magazine Simons has a net worth of $18 billion United States dollar as of February 2017. This makes him #24 on the Forbes 400 richest people list.^[35]

In 2014, Simons reportedly earned $1.2 billion including a share of his firm's management and performance fees, cash compensation and stock and option awards.^[36]

In 2011, he was included in the 50 Most Influential ranking of Bloomberg Markets Magazine. Simons owns a motor yacht, named Archimedes. It was built at the Dutch yacht builder Royal Van Lent and delivered to Simons in 2008.^[37]

Simons and his second wife, Marilyn Hawrys Simons, co-founded the Simons Foundation in 1994, a charitable organization that supports projects related to education and health, in addition to scientific research.^[38] In memory of his son Paul, whom he had with his first wife, Barbara Simons, he established Avalon Park, a 130-acre (0.53 km²) nature preserve in Stony Brook. In 1996, 34-year-old Paul was killed by a car driver while riding a bicycle near the Simons home. Another son, Nick Simons, drowned at age 24 while on a trip to Bali in Indonesia in 2003. Nick had worked in Nepal. The Simons have become large donors to Nepalese healthcare through the Nick Simons Institute.^[39][40]

The Simons Foundation established the Simons Foundation Autism Research Initiative (SFARI) in 2003 as a scientific initiative within the Simons Foundation's suite of programs. SFARI's mission is to improve the understanding, diagnosis and treatment of autism spectrum disorders.^[41]

In 2004, Simons founded Math for America with an initial pledge of $25 million from the Simons Foundation, a pledge he later doubled in 2006.^[42]

Also in 2006, Simons donated $25 million to Stony Brook University through the Stony Brook Foundation, the largest donation ever to a State University of New York school at the time.^[43]

On February 27, 2008, then Gov. Eliot Spitzer announced a $60 million donation by the Simons Foundation to found the Simons Center for Geometry and Physics at Stony Brook, the largest gift to a public university in New York state history.^[44]

Via the foundation, he and Marilyn also funded the renovation of the building housing the mathematics department at MIT, which in 2016 was named after the two of them.^[45]

Through the foundation, Simons has been a major benefactor of the University of California, Berkeley. On July 1, 2012, the Simons Foundation provided a $60 million grant to Berkeley to establish the Simons Institute for the Theory of Computing, the world's leading institute for collaborative research in theoretical computer science.^[46] The foundation has also made other major gifts to Berkeley, notably to its Mathematical Sciences Research Institute.^[47][48]

The Simons Foundation established the Flatiron Institute in 2016, to house 4 groups of computational scientists (each with 60 or more PhD level researchers). The institute consists of three cores or departments: CCB (the center for computational biology), CCA (Center for Computational Astrophysics), CCQ (Center for Computational Quantum mechanics). A fourth, yet to be assembled core, will focus on another branch of applied computational science. The new institute is located in Manhattan and represents a major investment in basic computational science.

9. Legacy and Awards

In 2008, he was inducted into Institutional Investors Alpha's Hedge Fund Manager Hall of Fame along with David Swensen, Louis Bacon, Steven Cohen, Kenneth Griffin, Paul Tudor Jones, George Soros, Michael Steinhardt, Jack Nash, Seth Klarman, Alfred Jones, Leon Levy, Julian Roberston, and Bruce Kovner.^[49]
