Lesbian fiction in English saw a huge explosion in interest with the advent of the dime-store or pulp fiction novel. Lesbian pulp fiction became its own distinct category of fiction in the 1950s and 60s, although a significant number of authors of this genre were men using either a male or female pen name. Tereska Torrès is credited with writing the first lesbian pulp novel, "Women's Barracks", a fictionalized story about women in the Free French Forces during World War II. The 1950 book sold 2 million copies in its first five years of publication. One notable female author of lesbian pulp fiction, who came out later in life as a lesbian, was Ann Bannon, who created the Beebo Brinker series.
