Born in Chicago, she worked in the United States Army Air Force as an intelligence officer, where she rose to the rank of Major. She began to write science-fiction under the Tiptree pseudonym in 1967. Her short stories and novellas have received numerous prizes, including multiple Hugo, Nebula and Locus awards. She was inducted into the Science Fiction Hall of Fame in 2012.
