144. Paul Tudor Jones II
The founder of hedge fund firm Tudor Investment is known for his astute macro trades, but Jones didn’t always have a hot hand. Slightly built as a kid, Paul kept trying team sports but was too small to compete. In the 10th grade he turned to boxing, which allowed him to fight rivals his own size, and eventually became a welterweight champion at the University of Virginia with a career 20–2 record. In 1986, he adopted a class of 6th graders in Brooklyn, promising to pay for college if they graduated high school, but found out after 6 years of work that his kids did no better than students from nearby schools. Concluding that change has to start earlier than age 12, Jones started the first all-boys charter school in the nation in 2004. He also cofounded antipoverty charity Robin Hood Foundation.
