In 1953, he married writer Julian May, whom he had met at a science fiction convention in Ohio. Both of them worked for Chicago-area publishers; in 1957 the two started Publication Associates, an editorial service which created books (from writing to completion of bound copies) for specialty children's publishers who sold primarily to the school and library markets: May did the writing, and Dikty served as designer and producer. In the early 1970s Dikty and partners started a small press, FAX Collector's Editions, which reprinted selected pulp-era (and earlier) SF stories and novels, and had some commercial success with reprints of work by Robert E. Howard (creator of Conan the Barbarian).
In 1976, after the family had moved to West Linn, Oregon, Dikty founded the specialty publisher Starmont House, which published non-fiction about the science fiction field. At the time of his death in 1991 at the age of 71, Dikty and May had moved in Mercer Island, Washington; his daughter, Barbara Dikty, had already been made President of Starmont House, Inc. by then.
