Ottorino Mezzalama (born 25 September 1888 – 23 February 1931[1]) was an Italian mountain climber, and is deemed to be one of the two pioneers of Italian ski mountaineering besides Luciano Roiti. He died in an avalanche accident in the Rochemolles Valley. The Ottorino Mezzalama Hut of the Club Alpino Italiano (CAI) below Pollux as well as the famous Mezzalama Trophy competition and the Mezzalama Skyrace were named in honor of him.
