Philanthropy

This billionaire hedge fund manager is known as a financial wunderkind, which is good for all the organizations out there that this low-profile philanthropist helps to fund. Some of those organizations include the American Jewish Committee and the Israel Project, as well as several Jewish foundations in his home state of Massachusetts. Klarman is also the lead investor in The Times of Israel, a Jerusalem-based, Israel focused news-website that launched in 2012 and quickly gained a large following.
