He was born in Massieville, Ohio and grew up in Coalton, Ohio. He took up his father's profession as a photographer and later became an interior decorator. He briefly performed in a circus band and in the National Guard, playing cornet and alto horn. His earliest works were published during the Spanish–American War with a later spurt of activity around World War I. After the later war, he settled down in Chillicothe, Ohio where he led an Odd Fellows band until his death in 1942.
