Born in Providence, Rhode Island, George Michael Cohen developed his skills as a performer from an early age. As a boy, he traveled the country with his family in a vaudeville act called the Four Cohans. During his youth, he learned to play the violin, as well as write sketches and songs for the family. He expanded his sketches into longer shows, and his first full-length musical comedy was Little Johnny Jones in 1904.
Some of Cohan's most famous songs are "You're a Grand Old Flag," "Yankee Doodle Boy," and "Give My Regards to Broadway." He was wildly successful for two decades writing and producing shows on Broadway. He also was an excellent actor himself, performing in plays by Eugene O'Neill and Rogers and Hart.
Cohan wrote more than 500 songs.
