Jim Simons (April 25, 1938 – May 10, 2024)

The Andrei Sakharov Foundation is deeply saddened by the death of an outstanding mathematician, a hedge fund manager who pioneered quantitative research, and a philanthropist, Jim Simons. We offer our sincere condolences to Marilyn Simons and the entire family.

A brilliant mathematician, Jim made significant contributions in the field of string theory, quantum field theory, and condensed matter physics, before deciding to apply his remarkable talent to the world of finance. The long-​term investment returns on his funds made him the “greatest investor on Wall Street” and the most successful hedge fund manager of all time.

The Simons Foundation, founded by Jim and Marilyn thirty years ago, in 1994, supports research in mathematics and fundamental sciences. Jim was active in the philanthropic work until the last day of his life.
