Nicknamed “Dr. Death,” Kevorkian's controversial ideas and views on death and the act of dying fueled his reputation as an outsider in the 1950s. But it was his eventual crusade and participation in assisted suicide in the late 1980s and early '90s that made him notorious. Kevorkian assisted in the suicide of Alzheimer's patient Janet Adkins using his “Thanatron”—Greek for “instrument of death.” After his medical license was revoked and he was barred from using his “suicide machine,” he continued his efforts with other methods. Assisted suicide became a felony in Michigan in 1998, and, in that same year, Kevorkian allowed CBS' “60 Minutes” to air a tape he had made where he injected the patient himself. He was convicted of second-degree murder and served 8 years of his sentence, after which he gave lectures, ran for Congress and had an HBO film made about his life.
