George M. Cohan
George Michael Cohan , known professionally as George M. Cohan, was an American entertainer, playwright, composer, lyricist, actor, singer, dancer and producer.
Cohan was born in 1878 in Providence, Rhode Island, to Irish Catholic parents. A baptismal certificate from St. Josephs Roman Catholic Church indicated that he was born on July 3, but Cohan and his family always insisted that George had been born on the Fourth of July! Georges parents were traveling vaudeville performers, and he joined them on stage while still an infant, first as a prop, learning to dance and sing soon after he could walk and talk.
