Gloria Hemingway (born Gregory Hancock Hemingway, November 12, 1931 – October 1, 2001) was an American physician and writer who was the third and youngest child of author Ernest Hemingway. Although she was assigned male at birth and lived most of her life publicly as a man, she struggled with her gender identity from a young age, and in her sixties she underwent surgery to transition, preferring the name Gloria when possible.
A good athlete and a crack shot, Gloria longed to be a typical Hemingway hero and trained as a professional hunter in Africa, but her alcoholism prevented her gaining a license, as it also cost her her medical license in America. Gloria maintained a long-running feud with her father, stemming from a 1951 incident when her arrest for entering a bar "in drag" caused an argument between Ernest and Gloria's mother Pauline. Pauline died from a stress-related condition the next day, which Ernest blamed on Gloria and Gloria later believed to have been caused by Ernest.
