C.G. Conn Musical Instruments at The Mighty Quinn Brass and Winds
Charles Gerard Conn was the patriarch of musical instrument manufacturing in Elkhart, Indiana. In 1873, following a bar fight which resulted in a split lip, Colonel C.G. Conn developed a brass mouthpiece with a more forgiving rubber rim. Conn converted an old sewing machine to a lathe and set up a shop building these mouthpieces. In 1875, a French instrument maker named Dupont began repairing instruments in Conn’s shop. After watching him work for a few days, Conn believed he could build his own instrument. Within that same year, Conn would build the first American-made cornet.
By 1879, Conn moved operations into larger quarters and began making other instruments. In 1880, the town of Elkhart, Indiana became so enamored with Colonel Conn that they elected him as their Mayor. During his second term, he was forced to resign due to a catastrophic factory fire. The factory was eventually rebuilt bigger and better and production resumed. By 1893 his instruments were awarded the highest honors in the World’s Columbia Exposition in Chicago.
The Colonel loved strange and bizarre instruments. In 1907, he built an immensaphone, the largest horn in the world at 12 feet in diameter and 35 feet long. He also continued on a series of “firsts”, building the first American made saxophone and the first sousaphone, built to John Philip Sousa’s specifications. Charles Gerard Conn ran the Conn company for 39 years, from its founding in 1876 until he sold all of his holdings in 1915
Carl Greenleaf was president of Conn from 1915 to 1949. The new company was incorporated with public stock offerings under the name C. G. Conn Ltd. and the Conn trademark was updated to the official name of the new company. In 1970, Conn sold its Elkhart factory to the Selmer Company. Conn-Selmer, headquartered in Elkhart, continues to produce instruments under the Conn name (notably brass instruments and saxophones)
C.G. Conn endures as a highly respected brand of US instrument manufacturing, especially celebrated for several legacy models such as the 88H Trombone, the 8D French Horn and the 6M and10M Saxophones.
