Margaret Mayo

Born Lillian Elizabeth Slatten in Brownsville, Illinois, in 1882, she first worked as an actress before turning fully to writing in the early 1900s. Sources consistently describe her as an American playwright and screenwriter, and several note that her early breakthrough came after she moved from acting into playwriting.

Her best-known works include Polly of the Circus (1907), Baby Mine (1910), and Twin Beds (1914), plays that made her one of the better-known commercial dramatists of her era. She also adapted work for film, and archival sources connect her with Goldwyn Pictures, where she served as head of the Scenario Department and took part in wartime entertainment work during World War I.

Margaret Mayo died in 1951 in Ossining, New York. Today, she is remembered as a versatile theater professional whose career moved easily between the stage and the early film industry.
