Margaret Mayo, born Lillian Elizabeth Slatten,[1] was an American actress, playwright, and screenwriter.

Later, she was educated at the Girl’s College in Fox Lake, Wisconsin; the Convent of the Sacred Heart in Salem, Oregon; and at Stanford University.

She worked as many things: adapter, actress, film company founding partner, playwright, and a writer.

However, Mayo is best remembered as the author of more original plays such as Polly of the Circus (1907), Baby Mine (1910), Twin Beds (1914), and Seeing Things (1920), written with Aubrey Kennedy.

[3] Mayo was instrumental in making housing arrangements for Indian spiritual teacher Meher Baba at Harmon, near New York City, during his first visit to America in 1931.
