All that can be presently gleaned about Charles F. Bauer is taken from the sheet music cover of Three Strikes (1902) written by brother Arthur W. Bauer. He was a member of John Philip Sousa's famous band as a trumpeter together with his brother and both were apparently members of the band's baseball team. The brothers published their compositions with their own Bauer Bros. Music Co., Oshkosh, Wisconsin, USA.
