Chicago married Gerowitz in 1961. He died in a car crash in 1963, devastating Chicago and causing her to suffer from an identity crisis until later that decade.
As Chicago made a name for herself as an artist, and came to know herself as a woman, she no longer felt connected to her last name, Cohen. This was due to the late grief of the death of her father and the lost connection to her name through marriage, Judith Gerowitz, after her husband's death. She decided she wanted to change her last name to something independent of being connected to a man by marriage or heritage. During this time, she married sculptor Lloyd Hamrol, in 1965. (They divorced in 1979.) Gallery owner Rolf Nelson nicknamed her "Judy Chicago" because of her strong personality and thick Chicago accent. She decided this would be her new name, and sought to change it legally.
