Irving Kahn, the oldest active investor on Wall Street, died at the age of 109 on Tuesday. According to the New York Times, he was also “the last surviving member of what had been described as the oldest living sibling quartet.” New York Magazine profiled Kahn in 2011. He began working on Wall Street in 1928, and continued going into the office three days a week up until last year for a short workday that “often include[d] a nice bowl of soup.” Reporter Jesse Green wrote, “’I don’t worry about dying,’ he says, assuming it will happen in his sleep. Instead he worries about staying mentally agile, which is why he reads three newspapers daily and watches all the C-Spans. ‘I know people collect postage stamps, but that’s just one thing. It’s about having multiple interests.’”
