Ivan Boesky, a onetime Wall Street titan who personified the excesses of the 1980s — helping inspire Hollywood’s fictional mogul Gordon Gekko and his greed-is-good mantra — but who came to a crashing end with insider-trading revelations that sent him to prison as part of one of the most sweeping securities scandals in history, died May 20 at his home in La Jolla, Calif. He was 87.
