       | Simons Foundation Co-Founder, Mathematician and Investor Jim
       | Simons Dies at 86 By Thomas Sumner May 10, 2024 Simons Foundation
       | co-founder and chair emeritus Jim Simons. (c) Beatrice de Gea
       | 
       | It is with great sadness that the Simons Foundation announces the
       | death of its co-founder and chair emeritus, James Harris Simons,
       | on May 10, 2024, at the age of 86, in New York City.
       | 
       | Jim (as he preferred to be called) was an award-winning
       | mathematician, a legend in quantitative investing, and an
       | inspired and generous philanthropist.
       | 
       | Together with his wife, Simons Foundation chair Marilyn Simons,
       | he gave billions of dollars to hundreds of philanthropic causes,
       | particularly those supporting math and science research and
       | education. In 1994, they established the Simons Foundation, which
       | supports scientists and organizations worldwide in advancing the
       | frontiers of research in mathematics and the basic sciences.
       | 
       | Jim was active in the work of the Simons Foundation until the end
       | of his life, and his curiosity and lifelong passion for math and
       | basic science were an inspiration to those around him. He was
       | determined to make a meaningful difference in the level of
       | support that mathematics and basic sciences received in the
       | United States, notably by sponsoring projects that were important
       | but unlikely to find funding elsewhere.
       | 
       | Over its 30-year history, the Simons Foundation's work has led to
       | breakthroughs in our understanding of autism, the origins of the
       | universe, cellular biology and computational science. Jim and
       | Marilyn's giving continues to support the next generation of
       | mathematicians and scientists at schools and universities in New
       | York City and around the world.
       | 
       | Jim frequently said that he went through three phases in his
       | professional life: mathematician, investor and philanthropist. He
       | previously chaired the math department at Stony Brook University
       | in New York, and his mathematical breakthroughs during that time
       | are now instrumental to fields such as string theory, topology
       | and condensed matter physics.
       | 
       | In 1978, Jim founded what would become Renaissance Technologies,
       | a hedge fund that pioneered quantitative trading and became one
       | of the most profitable investment firms in history. He then
       | turned his focus to making a difference in the world through the
       | Simons Foundation, Simons Foundation International, Math for
       | America and other philanthropic efforts.
       | 
       | "Jim was an exceptional leader who did transformative work in
       | mathematics and developed a world-leading investment company,"
       | says Simons Foundation president David Spergel. "Together with
       | Marilyn Simons, the current Simons Foundation board chair, Jim
       | created an organization that has already had enormous impact in
       | mathematics, basic science and our understanding of autism. The
       | Simons Foundation, an in-perpetuity foundation, will carry their
       | vision for philanthropy into the future."
       | 
       | Jim Simons is survived by his wife, three children, five
       | grandchildren, a great-grandchild, and countless colleagues,
       | friends and family who fondly recall his genuine curiosity and
       | quick wit.
       | 
       | We know that many people have stories, messages and memories they
       | would like to share about Jim. Please send them to
       | observing@simonsfoundation.org.
       | 
       | Information on memorial services and other events honoring Jim's
       | life and legacy will be posted on the Simons Foundation website.

       | heard of the Medallion fund before I was aware of the Simons

       | here or on reddit, mentioned Jim Simons as the connection.

       | SFARI in turn funds a lot of foundational neurological and rare
