Giulio Briccialdi

Giulio Briccialdi (1/2 March 1818 – 17 December 1881) was an Italian virtuoso flautist and composer, a technical innovator on his instrument and a professor of music.

Briccialdi was born in Terni. He is commonly credited for inventing the B-flat (or "Briccialdi") thumb key for the Boehm flute, but scholarship suggests that the innovation was Boehm's first. He died in Florence.
