Winston K. Marks (1915-1979) was an American author of science fiction short stories who also wrote as Win Marks and used the pseudonyms Win Kinney and Ken Winney, each for just one story. He began publishing with "Mad Hatter" for Unknown in May 1940, but then, after "Manic Perverse," was not heard of again until 1953 when he published The Water Eater. He was then quite prolific, publishing nearly 60 further stories to 1959, with two final SF Magazine appearances in the late 1960s. His style was mildly hard-bitten and amusing; several of his stories were anthologized. A posthumous collection is The Test Colony and Other Stories.
