Stanley K. Sheinbaum (June 12, 1920 – September 12, 2016) was an American peace and human rights activist. One of the so-called Malibu Mafia, Sheinbaum joined with other wealthy Angelenos to fund liberal and progressive causes and politicians. He organized the legal defense of Daniel Ellsberg who had released the Pentagon Papers, and he initiated Israel–Palestine talks which eventually brought about the Oslo Accords of 1993.
