On 11 March 1831, Johann Adam Heckel and Carl Almenräder founded the J. A. Heckel and Carl Almenräder bassoon factory. The two founders first met in 1829 at the Mainz Music Publishing House, Schott. The first bassoons by Heckel and Almenräder were also made for Schott and therefore were stamped with B. Schott Fils à Mayence.
