a Swiss geologist, meteorologist, physicist, mountaineer and Alpine explorer, often called the founder of alpinism and modern meteorology, and considered to be the first person to build a successful solar oven. 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.
