Ruth McKenney (November 18, 1911 – July 25, 1972) was an American author and journalist, best remembered for My Sister Eileen, a memoir of her experiences growing up in Ohio and moving to Greenwich Village with her sister Eileen McKenney. Originally published as a series of short stories in The New Yorker, My Sister Eileen was published in book form in 1938, and later adapted under the same name into a play, a radio play (and unproduced radio series), two films, and a CBS television series. It was also the basis for the Leonard Bernstein musical Wonderful Town.
Ruth Marguerite McKenney was born in Mishawaka, Indiana on November 18, 1911 to John Sidney McKenney, a mechanical engineer and Marguerite Flynn, a grade school teacher. Her younger sister, Eileen (born April 3, 1913), later married author Nathanael West.
In 1919 her family moved to East Cleveland, Ohio, where she lived until adulthood. She attended East Cleveland Evangelical Church.
She graduated from Shaw High School, where she skipped two grades. Among other subjects, she studied French. She was known as something of a tomboy and was the only girl to play on the East Cleveland boys baseball team (she played first base). She joined the Northern Ohio Debating League. She described herself as "homely as a mud fence", especially compared to her sister Eileen, though she likely exaggerated for comic effect. She also stuttered.
She attempted to commit suicide once during high school but was rescued by Eileen. At the age of 14, she ran away from home, worked as a printer's devil, and joined the International Typographical Union. At 16, she and Eileen got jobs as waitresses at the Harvey Tea Room at the Cleveland Union Station.
