The co-founder of Earth Day was initially just like you would expect – he was a bearded hippie who spoke at environmental rallies and preached about peace. His name was Ira Einhorn, and he was reportedly a charismatic activist who was well-known among environmental groups in the 1960s and 1970s. He was a popular figure in Philadelphia who supposedly co-founded Earth Day in 1970, and his original nickname was "Unicorn" because his last name (which is German and Jewish) translates to "one horn." He studied at the University of Pennsylvania and was staunchly against the Vietnam War. But there was a violent side to Einhorn that eventually came to light.
