Mario Lessona



Mario Lessona (18 December 1855 in Genoa – 25 December 1911 in Turin) was an Italian zoologist and malacologist. He was the son of the prominent natural scientist and senator Michele Lessona and his wife Adele Masi Lessona, who was very much involved in her husband's work, particularly in making translations. A son of Adele Lessona by an earlier marriage was the painter and malacologist Carlo Pollonera, with whom Mario published a monograph on Italian slugs. Mario also coauthored various scientific works with his brother-in-law, the zoologist and senator Lorenzo Camerano.
