Frank Crumit (September 26, 1889 – September 7, 1943) was an American singer, composer, radio entertainer and vaudeville star. He shared his radio programs with his wife, Julia Sanderson, and the two were sometimes called "the ideal couple of the air." 　　Crumit was born in Jackson, Ohio, the son of Frank and Mary (nee Poore) Crumit. He made his first stage appearance at the age of five in a minstrel show. 　　Attending local schools, Crumit graduated from high school in 1907. After briefly attending an Indiana military academy, he entered Ohio University and later Ohio State University. His primary purpose for entering Ohio University was to follow in the footsteps of his grandfather, Dr. C. K. Crumit, who had been a medical doctor. He instead graduated from Ohio University with a degree in electrical engineering. This career did not last long, as his passion seemed to be music and the old ballads of the 19th century; his love of music and theater dated back to his early years in the Methodist Church choir and led him to pursue a musical career. He studied voice in Cincinnati and then tried out unsuccessfully for opera in New York City. 　　By 1913, in his early 20s, he was performing on the vaudeville stage, first with a trio and then a year later on his own, playing ukulele; he was referred to as "the one-man glee club" in New York City's night spots. He appeared in the Broadway musical Betty Be Good in 1918, where he was the first to play the ukulele on Broadway.
