Ira Einhorn - Wikipedia, the free encyclopedia

Ira Samuel Einhorn, a.k.a. "The Unicorn Killer" (born May 15, 1940), is a convicted murderer, and former American activist of the 1960s and 1970s. He is now serving a life sentence for the 1977 murder of Holly Maddux.^[1]

Einhorn was active in ecological groups and was an icon of the counterculture, anti-establishment and anti-war movements of the 1960s and 1970s. At one time, he was a friend and contemporary of Jerry Rubin and Abbie Hoffman. He also claimed to have been instrumental in creating Earth Day in 1970, and claimed that during the first Earth Day event, he was on stage as master of ceremonies, although other event organizers dispute his account, including a rebuttal during testimony in Einhorn's murder trial.^[3][4]He called himself, poetically, "the Unicorn," because the name Einhorn (a German-Jewish name) means Unicorn, or more literally translated to "One Horn".^[5]
