Ottaviano Petrucci

Ottaviano Petrucci (18 June 1466 – 7 May 1539) was an Italian printer. His Harmonice Musices Odhecaton, a collection of chansons printed in 1501, is commonly misidentified as the first book of sheet music printed from movable type. Actually, that distinction belongs to the Roman printer Ulrich Han's Missale Romanum of 1476. Nevertheless, Petrucci's later work was extraordinary for the complexity of his white mensural notation and the smallness of his font, and he did in fact print the first book of polyphony using movable type.
