Serving as an enlisted man in occupied Germany after World War I, Gerber had learned of Magnus Hirschfeld's pioneering work. Upon returning to the U.S. and settling in Chicago, Gerber organized the first documented public homosexual organization in America and published two issues of the first gay publication, entitled Friendship and Freedom. Meanwhile, during the 1920s, LGBT persons found employment as entertainers or entertainment assistants for various urban venues in cities such as New York City. Homosexuals were occasionally seen in LGBT films of Pre-Code Hollywood. Buster Keaton's Seven Chances offered a rare joke about the female impersonator, Julian Eltinge. The Pansy Craze offered actors, such as Gene Malin, Ray Bourbon, Billy De Wolfe, Joe Besser, and Karyl Norman. In 1927, Mae West was jailed for The Drag. The craze found itself in a wide variety of American films, from gangster films like The Public Enemy, to musicals like Wonder Bar and animated cartoons like Dizzy Red Riding Hood.

George Hannah decided in 1930 to record the song, The Boy in the Boat." Kokomo Arnold recorded the song, "Sissy Man Blues" in 1935. Pinewood Tom (Josh White), George Noble, and Connie McLean's Rhythm Boys followed with their own records. While it seems that homosexuals enjoyed greater recognition in the media after World War I, many were still arrested and convicted for their deeds through state sodomy laws. For example, Eva Kotchever headed a lesbian café called Eve's Hangout in Greenwich Village. It was stated about her business that "men are admitted but
