Giorgio Colli (1917—1979) was an Italianphilosopher, philologist and historian. A native of Turin, taught ancient philosophy at Pisa's university for thirty years; he edited and translated Aristotle's Organon and the first complete edition of Nietzsche's work (including all the posthumous fragments chronologically ordered), together with his friend Mazzino Montinari. His work culminated in The Greek Wisdom, the edition and translation of the "Presocratics" (a term he rejected). Interrupted by his death in January 1979, it was supposed to be in eleven volumes.
