Jim Simons, the billionaire investor, mathematician, and philanthropist, has died at the age of 86, the New York Times reports.
According to CNBC, his cause of death has not been disclosed.
Simons earned his mathematics degree from MIT and a doctorate from UC-Berkeley.
After teaching briefly at MIT and Harvard, he worked as a code breaker for the National Security Agency before joining the Princeton Institute for Defense Analyses, where he opposed the Vietnam War and was fired.
His career took another turn when he founded Renaissance Technologies in 1982, CNBC reports.
At Renaissance, he pioneered quantitative investing, using mathematical and statistical models to identify investment opportunities.
In his later years, Simons turned his focus to philanthropy, becoming a significant political donor and supporter of science and math education and research.
His foundation has been instrumental in funding autism research and supporting various educational initiatives.
Last year, his foundation made headlines with a historic $500 million donation to Stony Brook University's endowment, the largest unrestricted gift to an American university.
Simons often reflected on his dual passions for mathematics and philanthropy.
"Mathematics was the only subject I liked," he said in a 2015 interview.
His life's work not only revolutionized financial markets but also greatly contributed to scientific and educational causes."
