Early Life and Education
Jim Simons was born in 1938 in Brookline, Mass., and discovered his love for mathematics at an early age. At the age of 14, Simons worked at a garden supply store as a floor sweeper after being demoted from a stock boy position due to his lack of memory of inventory location. However, Simons was astute and had the ambitious plan of becoming a mathematician at the Massachusetts Institute of Technology (MIT).
In 1955, Simons was accepted into MIT and majored in mathematics. Upon graduating, Simons studied at the University of California at Berkeley for his doctorate in mathematics. His thesis focused on providing supporting proof of Bergers classification of the holonomy groups of Riemannian manifolds, and after just one year, he received his doctorate at the age of 23 in 1961.
Later, Simons worked on important mathematical theories, including the Chern-Simons form, which later played a role in topological quantum field theory. He had an early and successful career in mathematics, winning multiple awards, and later was inducted into the U.S. National Academy of Sciences.
In 1964, Simons was recruited by The Institute for Defense Analyses (IDA), where he played a key role to break codes during the Vietnam War. Simons left IDA after four years and went on to teach mathematics at MIT and Harvard University.
Eventually, he was appointed to become the chair of the mathematics department at Stony Brook University, where he helped develop the mathematics and physics programs while still being sought after by companies such as IBM for his consulting work. It wasnt until 1978 that he started delving into finance.
Investment Philosophy & Success Story
Despite already having successful careers as a prize-winning mathematician and a master code breaker for the IDA, Jim Simons decided to pursue a career in finance. In 1978, the mathematician started the hedge fund Monemetrics, which was the predecessor to the highly successful Renaissance Technologies.
Simons didnt think to apply mathematics to his hedge fund at first; however, over time, he realized he could use mathematical and statistical models to interpret data by looking for non-random movements in financial data to predict future returns.
By 1988, Simons decided to solely use quantitative analysis to decide which trades to enter. Simons only sought experts in mathematics, data analysis, and many other scientific-related fields to work with him at the fund. The Quant King filled the fund with programmers, mathematicians, physicists, and cryptographers. The company thrived due to the complex mathematical formulas these scientists developed.
Since its inception, Renaissance Technologies flagship fund, the Medallion hedge fund, has generated over $100 billion in trading profits with an average annual return of 71.8% before fees between 1994 and mid-2014. Unfortunately, the Medallion fund is only available for its employees and family members.

Current Net Worth and Influence
Jim Simons ranked 23rd on Forbes wealthiest Americans list in 2020, with an estimated $23.5 billion net worth. The Quant King also ranks first on the Forbes 2019 list of highest-earning hedge fund managers.
Simons has a great deal of influence in the scientific world and co-founded the Simons Foundation with his wife, Marilyn Simons, in 1994. The Simons Foundation is devoted to supporting scientific research, education, and health. Simons has contributed over $2.7 billion of his wealth to this cause as well as to support autism research.
Additionally, Simons founded Math for America, which aims to encourage mathematics and science teachers to remain in their roles and advance their teaching abilities.
Jim Simons Quotes
Jim Simons is a big advocate of idea sharing and hiring the brightest people from various science-related fields. However, Simons frequently avoids the spotlight and doesnt give many interviews. The following quotes give just a sliver of insight into how hes managed and built Rentech.
Great people. Great infrastructure. Open environment. Get everyone compensated roughly based on the overall performance...That made a lot of money.
“We search through historical data looking for anomalous patterns that we would not expect to occur at random.”
Past performance is the best predictor of success.
We have three criteria: If its publicly traded, liquid, and amenable to modeling, we trade it.
Efficient market theory is correct in that there are no gross inefficiencies. But we look at anomalies that may be small in size and brief in time. We make our forecast. Then, shortly thereafter, we re-evaluate the situation and revise our forecast and our portfolio. We do this all day long. Were always in and out and out and in. So were dependent on activity to make money.
I disparage some for whom model-making was a part-time hobby, Simons once said as part of a speech at MIT in 2011. Simons made the remark when speaking about those who thought model-making was not useful in the real world.
