Which radical feminist shot Andy Warhol in 1968?

On June 3, 1968, radical feminist writer Valerie Solanas shot Andy Warhol and Mario Amaya, art critic and curator, at Warhol's studio. Before the shooting, Solanas had been a marginal figure in the Factory scene. She authored in 1967 the S.C.U.M. Manifesto, a separatist feminist tract that advocated the elimination of men; and appeared in the 1968 Warhol film I, a Man. Earlier on the day of the attack, Solanas had been turned away from the Factory after asking for the return of a script she had given to Warhol. The script had apparently been misplaced.

Amaya received only minor injuries and was released from the hospital later the same day. Warhol was seriously wounded by the attack and barely survived: surgeons opened his chest and massaged his heart to help stimulate its movement again. He suffered physical effects for the rest of his life, including being required to wear a surgical corset. The shooting had a profound effect on Warhol's life and art.
