[1] Belmont was formed by John L. Goldwater, Louis Silberkleit, Maurice Coyne, the co-founders of Archie Comics, who also ran the pulp magazine publisher Columbia Publications.
When Columbia was shut down in 1960 (due to the demise of the pulp industry), Goldwater, Silberkleit, and Coyne immediately formed Belmont Books.
[1] According to the son of one of the founders, the name of the company came from Belmont Park, as the owners were fans of horse racing.
Rather than bookstores, their books were sold in railroad stations, airports, bus terminals, drug stores, and the lobbies of office buildings and hotels.
From 1969 to 1970, Belmont published a series of sword and sorcery novels by Gardner Fox, featuring the barbarian character Kothar.
