Jim Simons’s biography mentioned another notable investor, Ed Thorp. I’d read Thorp’s biography, A Man for All Markets: From Las Vegas to Wall Street, How I Beat the Dealer and the Market, but I started reading it again.

This quote sums up Thorp’s life:

“In the abstract, life is a mixture of chance and choice. Chance can be thought of as the cards you are dealt in life. Choice is how you play them. I chose to investigate blackjack. As a result, chance offered me a new set of unexpected opportunities.”

Thorp was a college professor, started two quantitative hedge funds, and created a blackjack revolution. He’s ninety-one now and still doing chin-ups and push-ups.

Where he started, the distance he traveled, and his choices along the way are all notable.

He was born during the Depression to struggling parents. Ten relatives lived in his home, and he attended one of the worst-ranked high schools in his city. Seeing how the Depression and World War I had shaped his father’s future, he vowed to do better.

Thorp shrewdly recognized that he could use math and science to change his life if he ranked first in the state’s chemistry exam. He finished fourth but took the physics exam the next year and ranked first. He received a full scholarship to UC, Berkeley (and transferred to UCLA for financial and social reasons). His decision to focus on acing state exams did indeed change his life’s trajectory.

While working toward his master’s in physics and PhD in mathematics at UCLA, he wondered if math could improve the odds of winning at blackjack and roulette. While on a teaching assignment at MIT and with the help of Claude Shanon, the “father of information theory,” he proved that they could, in both games. He shared his blackjack findings in an academic paper and a bestselling book, sending armies of blackjack players to Las Vegas. His curiosity about gambling led to unexpected highs and lows. He was introduced to the underworld of Las Vegas and was nearly killed. But book royalties and gambling winnings gave him his first financial cushion.

Thorp reflected on the type of life he wanted to live. He didn’t want to live in casinos and deal with shady people. He wanted to follow his curiosity, solve math problems, and work with smart people. He became a professor at New Mexico State University and began investing his savings—but his investments lost money. He wondered if math could improve his odds as an investor. He began looking for a link between math and the market. His curiosity—about the stock market this time—would change the trajectory of his life . . . again.

Thorp was dealt a tough hand, but he was able to change his life through good decision-making. His curiosity and love for math led to breakthrough discoveries in gambling and to working with the brilliant Claude Shanon. His decision to share that knowledge led to more opportunities and improved his finances. By age 29, his life had drastically improved. His next decision would propel his life to unimaginable heights.
