A Broadway actor and writer best remembered for the Western melodrama The Round-Up, he helped bring turn-of-the-century stage excitement to popular audiences. His surviving credits show a career that crossed both performance and playwriting in New York theater.

Born in 1866, Edmund Day was an American actor and playwright associated with Broadway at the turn of the 20th century. Records on Wikisource identify him as a United States actor and writer of Broadway melodramas, and theater databases credit him with works including The Head Waiters, Pals, and his best-known play, The Round-Up.
The Round-Up opened on Broadway in 1907 and became the work most closely linked with his name. The story later circulated in novelized form as The Round-Up: A Romance of Arizona, helping preserve Day’s reputation with readers as well as theater historians.
The basic outline of his life is clear, but some biographical details appear inconsistent across online sources, so it is safest to say that he lived from 1866 to 1923 and worked in New York’s stage world as both a performer and a writer.
