ANDY WARHOL was apparently inspired to create the screenprint "Electric Chair" by the 1964 execution of Americans Julius and Ethel Rosenberg who were accused and convicted of passing information about the atomic bomb to Russia during World War II. His "Death and Disaster" series used the repetition of images to convey desensitization to death.The artist was interested in the reality he described as “when you see a gruesome picture over and over again, it doesn’t really have an effect.”
