Biography of Heinrich Kummer
The information for Kummer in Russian sources is very scanty. It is mentioned only, that he was a teacher of music in St. Peterburg. Who was this mysterious person?
Heinrich Gotthelf Kummer was a German musician, born on 8 November, 1809, in Dresden. He was the only son of the German bassoon virtuoso Gotthelf Heinrich August Kummer.
Gotthelf Kummer was born on 23 January, 23, 1774 in Neustadt, near Dresden, as the third son of Johann Gottfried Kummer (1730-1812), the founder of the famous German musical family Kummers. Gotthelf was trained the music from his father and practiced chiefly on the bassoon, touring with great success in many European countries. Gotthelf Kummer died in Dresden on January 28, 1857.
Following the steps of his father, Heinrich Kummer became a bassoon player and pianist, but never managed to approach his father's success. Instead of that, he demonstrated outstanding capabilities in the rather distant from the music field—mechanics.
Heinrich concerted with success with his father all over the Germany from being 6 years old, playing the piano and later bassoon. For example, in 1816, after a series of concerts, last in Munich, the King Maximilian I Joseph of Bavaria awarded them with 300 golden ducats. In 1832 however, trying unsuccessfully to obtain a good permanent position as a musician, Heinrich leaved for two years for Poland, (a Russian province then), working as a piano teacher in the family of the former administrator of the Lowicz principality. In 1834 he went to St. Petersburg, Russia, where in 1837 he joined the Imperial Russian theater and opera orchestra as first bassoonist.
In 1847, after serving for 10 years, he received a full pension and left Russia in 1848 for Switzerland, and in 1851 he moved back to his home city, Dresden, where he continued to work as a music teacher.
While in St. Petersburg, Kummer designed not only his famous adding device, but also a bridge over Neva (in 1837), allowing traffic over the bridge while ships could simultaneously pass under it. The project was never realized, but the plan was at least in 1953 preserved at Leningrad city archives. Studying for years birds and insects, Kummer constructed several automatic devices, powered by watch springs, which imitated the movement of fish in water and flying bird.
The System Kummer rifle from 1874
Back in Switzerland and Germany, Heinrich Kummer was evidently more interested in shooting and rifles than in calculating devices. He made his rifles himself and even constructed a new System Kummer rifle (see the upper image), which received prizes on several exhibitions in Frankfurt, Bremen and Vienna. He even wrote a book about shooting.
Heinrich Kummer died on March 20th, 1880, in Dresden.
