Key Takeaways
- • Jim Simons, the mathematician who founded quantitative hedge fund Renaissance Technologies, died at age 86 at his New York City home after a battle with lung cancer, according to Science.
- • At his death Simons was worth about $31 billion per Forbes, and he and his wife Marilyn gave billions through the Simons Foundation, which reported more than $4 billion in assets in 2023.
- • Foundation president David Spergel says Simons ensured the foundation would continue operating normally after his death.
- • Major gifts include $90 million toward the $110 million Simons Observatory in Chile and a $500 million 2023 gift to Stony Brook University, the largest unrestricted gift to a U.S. university.
- • Simons' legacy spans basic science funding, the Flatiron Institute, and the Quanta and The Transmitter publications, alongside criticism over offshore tax-sheltered assets.
Summary
Jim Simons, a mathematics prodigy who left academia to build the world's first quantitative investment firm, died last week at age 86 at his home in New York City after a battle with lung cancer, according to Science. Late in his life, Simons and his wife Marilyn gave billions of dollars through their foundation to support basic research in math, physics, astronomy, computer science, and neuroscience, along with educational and humanitarian programs. David Spergel, president of the Simons Foundation, which reported more than $4 billion in assets in 2023, said Simons was curious and deeply interested in science, and that he took care to ensure the foundation would continue operating normally after his death.
Simons earned a Ph.D. in math from the University of California, Berkeley in 1962 at age 23, after graduating from MIT in 1958. He later worked as a code breaker for the Institute for Defense Analyses, a National Security Agency contractor, and was fired in 1968 after publicly opposing the Vietnam War. He then led Stony Brook University's math department, where he worked with Shiing-Shen Chern on the Chern-Simons theory. In 1978 he left Stony Brook to found Renaissance Technologies, which recruited scientists rather than financiers to find patterns in markets. According to Forbes, Simons was worth some $31 billion at his death.
In 1994, Simons and Marilyn established the Simons Foundation. Its largest efforts include the Flatiron Institute, which applies computational methods across math, quantum physics, biology, astrophysics, and neuroscience, and funding for the Quanta Magazine and The Transmitter, both editorially independent. The foundation has also backed arXiv since 2011. It contributed $90 million to the $110 million Simons Observatory in Chile's Atacama Desert, which recently began operations and aims to map the cosmic microwave background in search of gravitational wave evidence. Simons also funded Math for America and gave Stony Brook $500 million in 2023, the largest unrestricted gift to a U.S. university.
Simons also made personal philanthropic commitments after two of his sons died in separate accidents, funding causes in their names in Nepal and in New York state, and launching an autism research initiative. Simons faced criticism in 2017 for keeping $8 billion sheltered in a Bermuda offshore fund, which he said was intended for future charitable use, and in 2021 Renaissance investors paid as much as $7 billion to settle a federal tax dispute. Spergel said one of Simons' last wishes was to see early data from the Simons Observatory, which he did shortly before he died.
