Horace Bénédict de Saussure and others descending Mont Blanc. Horace-Bénédict de Saussure (February 17, 1740 - January 22, 1799) was a Genevan geologist, meteorologist, physicist, mountaineer and Alpine explorer, often called the founder of alpinism and modern meteorology. His early interest in botanical studies and glaciers led Saussure to undertake journeys across the Alps. In 1767, he completed his first tour of Mont-Blanc, a trip that did much to reveal the topography of the snowy portions of the Alps of Savoy. He also carried out experiments on heat and cold, on the weight of the atmosphere and on electricity and magnetism. For this, he devised what became one of the first electrometers. The Alps were the focus of Saussure's investigations. He saw them as the grand key to the true theory of the earth, and they gave him the opportunity to study geology in a manner never previously attempted. He closely examined the inclination of the strata, the nature of the rocks, the fossils and the minerals. All of Saussure's observations and experiments from seven Alpine journeys were summed up and published in four quarto volumes, under the general title of Voyages dans les Alpes (1779-96). He died in 1799 at the age of 58. Aquatint, not artist credited.
