Kummer was born on 10 December 1795 in Erlau in Thuringia (in Sankt Kilian.) [2] He taught himself the flute while learning violin, horn, trumpet, clarinet, bassoon, oboe, cello and double bassoon.[3]
Kummer was taught by Neumeister for a year, then took training in music theory from the Cantor of Schleusingen, Gottlob Abraham Stäps. From 1835, he worked as a flautist at the chapel of the Duke of Saxe-Coburg and Gotha, and took over direction of their orchestra in 1854.[4]
His published compositions ran to over 150 opus numbers, mostly involving the flute, but also including lieder, etc.
^German Wikipedia. Note that there are bassoon works by a "G. Kummer" (which have been uploaded to IMSLP), but they are not generally or probably by "Gaspard" Kummer but rather by his contemporary, a bassoonist Gotthelf Kummer. (The trouble with initials.)
