(born 1946) Michael Milken helped forge the corporate junk bond concept that fueled explosive profit earnings for Wall Street securities traders in the 1980s. After amassing a personal fortune in the hundreds of millions of dollars, Milken was arrested for his involvement in an illegal, insider-trading scheme with Ivan Boesky. He pleaded guilty to securities fraud in 1990 and served two years in federal prison, in addition to paying millions in government fines and civil damages. The Boesky—Milken scandal raised public awareness of the growing threat of white-collar crime. Since his release from jail, Milken has endeavored to establish a Consortium for Prostate Cancer Research.
