André Cailleux

André Cailleux, born André de Cayeux de Senarpont in Paris in 1907, was a French geologist and paleontologist known as a pioneer of planetary geology. After his doctorate in 1942 he became a specialist in glacial and periglacial morphology and took part in missions to America, Greenland, Poland, Guyana, Mauritania, the Sahara and Antarctica, representing the French government on an American polar expedition in 1960. From as early as 1948 he applied geological methods to the Moon, Mars and other planets, an interest that led him to the Paris-Meudon observatory. He taught at the Sorbonne, Université Laval and the California Institute of Technology, and published about 390 works on geomorphology, oceanography, hydrology, glaciology, petrography, mineralogy, geography, paleontology, planetary geology and the history of science. His books include Les Roches, La Glace et les glaciers and L'Antarctique.
