Mario Ponzo

Mario Ponzo (23 June 1882 – 9 January 1960) was an Italian academic psychologist. He was born in Rome and studied under Federico Kiesow at Turin where, in 1911, he published an article in the journal Archives Italiennes de Biologie which presented the well-known optical illusion known as the Ponzo illusion. In the same year he wrote for the Atti della Regia Accademia delle Scienze di Torino what has been described as the first article in Italian on psychology and the cinema. In 1931 he succeeded Sante De Sanctis to the chair in psychology at the Università degli studi di Roma "La Sapienza".
