Jim Simons, the renowned mathematician and Wall Street quant legend, dies at the age of 86

Jim Simons, the pioneering investor and Wall Street investor, has passed away at the age of 86. The Simons Foundation announced the sad news of its co-founder and chair emeritus’s passing earlier today. Known as Jim to those close to him, he was an award-winning mathematician, a legend in quantitative investing, and an inspired and generous philanthropist.

“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,” Thomas Sumner said in a post on Simons Foundation website.

Together with his wife, Marilyn Simons, Jim contributed billions of dollars to numerous philanthropic causes, with a special focus on supporting math and science research and education. Their philanthropic journey began in 1994 when they established the Simons Foundation, dedicated to advancing research in mathematics and the basic sciences across the globe.

Jim remained actively involved in the foundation’s work until his last days, his passion for math and basic science serving as an inspiration to those around him. He was committed to enhancing support for mathematics and basic sciences in the United States, often backing projects that struggled to secure funding elsewhere.

Throughout its three-decade history, the Simons Foundation has played a pivotal role in various breakthroughs, including advancements in autism research, our understanding of the universe’s origins, cellular biology, and computational science. The legacy of Jim and Marilyn’s generosity continues to nurture the next generation of mathematicians and scientists worldwide.

Jim often reflected on his professional journey, dividing it into three phases: mathematician, investor, and philanthropist. Before delving into investment, he chaired the mathematics department at Stony Brook University in New York, where his contributions laid the groundwork for significant developments in fields like string theory and topology.

In 1978, Jim founded what would evolve into Renaissance Technologies, a hedge fund that revolutionized quantitative trading and achieved remarkable profitability. Later, he shifted his focus to philanthropy, channeling his efforts through organizations like the Simons Foundation, Simons Foundation International, and Math for America.

“Jim was an exceptional leader whose work in mathematics and investment transformed industries,” remarked David Spergel, president of the Simons Foundation. “Alongside Marilyn Simons, his vision has left an indelible mark on mathematics, basic science, and autism research. The Simons Foundation, an enduring legacy, will continue to uphold their philanthropic vision.”

Simons was estimated to have a net worth of $29.4 billion, placing him as the 52nd-richest individual globally, according to the Bloomberg Billionaires Index in 2023.

Jim Simons is survived by his wife, three children, five grandchildren, a great-grandchild, and a multitude of colleagues, friends, and family who fondly remember his genuine curiosity and sharp wit.
