Thomas Nicholas Scortia (August 29, 1926 – April 29, 1986) was an American science fiction author.
He sometimes used the pseudonyms "Scott Nichols", "Gerald MacDow", and "Arthur R. Kurtz".
He worked for a number of aerospace companies during the 1950s and 1960s/early 1970s, and held a patent for the fuel used by one of the Jupiter fly-by missions.
When the industry began to see increased unemployment in the early 1970s, Scortia decided to try his hand at full-time writing.
Scortia died in La Verne, California on April 29, 1986 while being treated for leukemia.
