George Michael Cohan (July 3, 1878 - November 5, 1942), known professionally as George M. Cohan, was an American entertainer, playwright, composer, lyricist, actor, singer, dancer and producer. Cohan began his career as a child, performing with his parents and sister in a vaudeville act known as "The Four Cohans." Beginning with Little Johnny Jones in 1904, he wrote, composed, produced, and appeared in more than three dozen Broadway musicals. Cohan published more than 300 songs during his lifetime, including the standards "Over There", "Give My Regards to Broadway", "The Yankee Doodle Boy" and "You're a Grand Old Flag".

From 1899 to 1907, Cohan was married to Ethel Levey (1881-1955; born Grace Ethelia Fowler), a musical comedy actress and dancer. Levey and Cohan had a daughter, actress Georgette Cohan Souther Rowse (1900-1988). Levey joined the Four Cohans when Josie married, and she starred in Little Johnny Jones and other Cohan works. In 1907, Levey divorced Cohan on grounds of adultery.  In 1908, Cohan married Agnes Mary Nolan (1883-1972), who had been a dancer in his early shows; they remained married until his death. They had two daughters and a son. The eldest was Mary Cohan Ronkin, a cabaret singer in the 1930s, who composed incidental music for her father's play The Tavern. In 1968, Mary supervised musical and lyric revisions for the musical George M!. Their second daughter was Helen Cohan Carola, a film actress, who performed on Broadway with her father in Friendship in 1931. Their youngest child was George Michael Cohan, Jr. (1914-2000), who graduated from Georgetown University and served in the entertainment corps during World War II. In the 1950s, George Jr. reinterpreted his father's songs on recordings, in a nightclub act, and in television appearances on the Ed Sullivan and Milton Berle shows. George Jr.'s only child, Michaela Marie Cohan (1943-1999), was the last descendant named Cohan. She graduated with a theater degree from Marywood College, Scranton, Pennsylvania, in 1965. From 1966 to 1968, she served in a civilian Special Services unit in Vietnam and Korea. In 1996, she stood in for her ailing father at the ceremony marking her grandfather's induction into the Musical Theatre Hall of Fame at New York University.  Cohan was a devoted baseball fan, regularly attending games of the former New York Giants.  He died of cancer at the age of 64 on November 5, 1942, at his Manhattan apartment on Fifth Avenue, surrounded by family and friends. He received his last rites from Mgr. John J. Casey, representing Archbishop Francis Spellman, and Rev. Francis X. Shea, vicar of the Archdiocese of New York. His funeral was held at St. Patrick's Cathedral, New York and was attended by thousands of people, including five governors of New York, two mayors of New York City and the Postmaster General. The honorary pallbearers included Irving Berlin, Eddie Cantor, Frank Crowninshield, Sol Bloom, Brooks Atkinson, Rube Goldberg, Walter Huston, George Jessel, Connie Mack, Joseph McCarthy, Eugene O'Neill, Sigmund Romberg, Lee Shubert and Fred Waring. Cohan was interred at Woodlawn Cemetery in The Bronx, New York City, in a private family mausoleum he had erected a quarter century earlier for his sister and parents.
