"Open the Door, Richard" began as a black vaudeville routine. Pigmeat Markham, one of several who performed the routine, attributed it to his mentor Bob Russell. According to Markham, Russell wrote the piece for a show called Mr. Rareback, in which the comedian John Mason performed it (and presumably expanded it in improvisation). Mason, Russell, and Markham were all African-American comedians; all performed in blackface.
The routine was made famous by Dusty Fletcher on stages such as the Apollo Theater in New York City and in a short film. Dressed in rags, drunk, and with a ladder as his only prop, Fletcher would repeatedly plunk the ladder down stage center, try to climb it to knock on an imaginary door, then crash sprawling on the floor after a few steps while shouting, half-singing "Open the Door, Richard". After this, he would mutter a comic monologue, then try the ladder again and repeat the process, while the audience was imagining what Richard was so occupied doing.
