Horn-u-Copia's Display of Makers

Theophil Marcus Koeder Worked for Holton in Chicago from 1907 to 1918. He established his own business in 1920. He used his own name and also used Blo-Rite as trade names.

Mr. T.M. Koeder was a music teacher in Naperville Il. and also had a home based business on School Street where he would repair and build trumpets.

He custom built these trumpets for various clients over the years, from around 1920 to about the time of his death in the early 1970s. His son then took over the business after he retired as a teacher, and continued repairing and building custom built instruments until his death in the late 1980s.
