When Warren Buffet was just a young early-career businessman, he wanted to join a country club. Although he wasn’t Jewish, he was so angry that his local country club banned Jews that he applied to join the Jewish country club instead. The Jewish country club wasn’t sure they accepted non-Jews, but local rabbi Myer Kripke spoke in Buffett’s favor and he was eventually accepted. Buffett repaid the rabbi’s kindness by helping him invest his money. He turned Rabbi Kripke’s life savings of $70,000, into $25 million, helping the rabbi and his wife become two of America’s leading Jewish philanthropists. Extra bonus facts: Rabbi Kripke was the father of Saul Kripke, sometimes considered the greatest modern philosopher, and the second cousin of Eric Kripke, showrunner for The Boys.
