His family lost a loving father and a devoted husband, the world of computing a great scien- tist, and our world at large a very kind and generous person. Stamatis was born in 1951 in the small village Manolates, on the island of Samos, in Greece. After his study at Politechnico di Milano, Stamatis moved to USA and worked for IBM at the Advanced Workstations and Systems laboratory in Austin, Texas, the Mid-Hudson Valley laboratory in Poughkeepsie, New York, and the Glendale laboratory in Endicott, New York. At IBM, he has been involved in a number of projects regarding com- puter design, organizations, and archi- tectures and in the leadership of advanced research projects.
