Gatti, a member of the Società Reale Italiana di Geografia ed Antropologia, was among the last great safari expedition men. He led thirteen expeditions to Africa starting in 1922. Broke after the financial disaster of his 7th African expedition, Gatti settled in the US in 1930. His second spouse EllenEllen Morgan Waddill Gatti (b. 1893 (or 1894) in Missouri, USA - d. 24.09.1962 in Ticino, Switzerland, 69 years old) accompanied him on his 8th expedition. They did the 10th (in Belgian Congo, 1938-1940) and 11th expeditions ("To the Mountains of the Moon" i.e. the Rwenzori Mountains at the border of Uganda, 1947-1948) with a caravan of motor vehicles including a 9-ton "Jungle Yacht", custom built by International Harvester in Chicago.
