T. D. Hamm

T. D. Hamm was the pen name of Thelma D. Hamm Evans (1905–1994), an American science fiction writer. Bibliographic sources identify her under several forms of her name, including Thelma D. Hamm and Thelma Hamm Evans.

She is best remembered for a handful of science fiction stories from the early 1950s, including "The Last Supper" and "Native Son." Her fiction appeared during a lively period for magazine science fiction, and later readers have continued to find her work through reprints and public-domain editions.

Reference sources also note that she married fellow science fiction writer E. Everett Evans in 1953, and that both were active in science-fiction fandom in the 1950s. Reliable biographical details beyond that seem limited, which gives her surviving stories an added sense of rediscovery for modern readers.
