Since I had to look him up anyway:

“Leon David Black (born July 31, 1951) is an American private equity investor. He is the former CEO of Apollo Global Management, which he co-founded in 1990 with Marc Rowan and Josh Harris. Black was the chairman of the Museum of Modern Art from 2018 to 2021. Black resigned from both Apollo Global Management and the Museum of Modern Art in the wake of sexual misconduct allegations and revelations that he had paid $158 million to Jeffrey Epstein.”
