Giulio Briccialdi (1/2 March 1818 – 17 December 1881)[1] 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,[2] but scholarship suggests that the innovation was Boehm's first.[3] He died in Florence.
