Calisto Tanzi (Collecchio, November 17, 1938) is an Italian businessman notorious for embezzling an estimated eight-hundred million euros from Italian company Parmalat, founded by him, resulting in a great loss for the company. Tanzi was the founder of Parmalat and its CEO, at the time. Tanzi founded Parmalat in 1961, after dropping out of college. Parmalat collapsed in 2003 with a 14bn euro ($20bn; £13bn) hole in its accounts in what remains Europe's biggest bankruptcy.
