From the German Wikipedia:
Camillo Schumann was the son of Königstein civic music director Clemens Schumann, senior, (1839-1918) and the younger brother of the composer Georg Schumann. Other siblings were Alfred Schumann (1868-1891), erstwhile concertmaster of the Bremen Philharmonic Orchestra, and Clemens Schumann, junior, (1876-1938), violinist from 1900 to 1936 in the Dresden Staatskapelle.
Like his brothers, Camillo Schumann received his first lessons on several instruments from his father during early childhood, From 1889 to 1893, he was enrolled at the Dresden Conservatory (briefly), then at the Leipzig Conservatory, where he studied with Carl Reinecke, Salomon Jadassohn, Bruno Zwintscher, Paul Homeyer and others. This was followed by study with Woldemar Bargiel and Robert Radecke in Berlin during 1894 and 1895.
During his time in Berlin Schumann served as a substitute organist in some of the larger churches. On 1 October 1896, he accepted the position as full-time organist at the main church of St. George in Eisenach and Wartburg Castle at the local chapel. In 1906 he was awarded the title Grand Ducal Saxon music director and organist. In Eisenach Schumann mounted a number of organ and chamber concerts - sometimes with the participation of his brothers Georg and Clemens.
In April 1914 he moved to Bad Gottleuba, taking over some church music commitments near his home, but devoting himself increasingly to his compositional work. Schumann died in Bad Gottleuba on 29 December 1946. His grave still exists today.
