Theobald Boehm

Theobald Böhm (or Boehm) (9 April 1794 – 25 November 1881) was a German inventor and musician, who greatly improved the modern Western concert flute and Clarinet and its fingering system (now known as the "Boehm system"). He was a Bavarian court musician, a virtuoso flautist and a renowned composer.

The fingering system he devised has also been adapted to other instruments, such as the oboe and the clarinet.
