Judy Chicago was born Judith Sylvia Cohen in 1939, to Arthur and May Cohen, in Chicago, Illinois. Her father came from a twenty-three generation lineage of rabbis, including the Vilna Gaon. Unlike his family predecessors, Arthur became a labor organizer and a Marxist. He worked nights at a post office and took care of Chicago during the day, while May, who was a former Dancer, worked as a medical secretary. Arthur's active participation in the American Communist Party, liberal views towards women and support of worker's rights strongly influenced Chicago's ways of thinking and belief. During the McCarthyism era in the 1950s, Arthur was investigated, which made it difficult for him to find work and caused the family much turmoil. In 1945, while Chicago was alone at home with her infant brother, Ben, an FBI agent visited their house. The agent began to ask the six-year-old Chicago questions about her father and his friends, but the agent was interrupted upon the return of May to the house. Arthur's health declined, and he died in 1953 from peritonitis. May would not discuss his death with her children and did not allow them to attend the funeral. Chicago did not come to terms with his death until she was an adult; in the early 1960s she was hospitalized for almost a month with a bleeding ulcer attributed to unresolved grief.
