Aldus Pius Manutius (1449/1450 – February 6, 1515), the Latinized name of Teobaldo Mannucci —sometimes called Aldus Manutius, the Elder (Italian: Aldo Manuzio il Vecchio) to distinguish him from his grandson, Aldus Manutius, the Younger—is an Italian humanist who becomes a printer and publisher when he founds the Aldine Press at Venice.

His publishing legacy includes the distinctions of inventing italic type, establishing the modern use of the semicolon, and introducing inexpensive books in small formats bound in vellum that were read much like modern paperbacks.
