François Émile Matthes [March 16, 1874 – June 21, 1948 (aged 74)] was a geologist and an expert in topographic mapping, glaciers, and climate change. He mapped remote areas of the American West for the United States Geological Survey (USGS). His maps coincided with the development of those areas into national parks. He is one of the founders of the Association of American Geographers and served as its president. Matthes resolved a dispute about formation of the Yosemite Valley and his findings on glaciers introduced the terms nivation and Little Ice Age.
Fraternal twins François and Gerard were born March 16, 1874 in Amsterdam, the Netherlands, to distinguished parents. Father, Willem Ernst Matthes [1842 - ?], was partner of the successful firm Matthes and Bormeester, importers of colonial rubber, indigo and hemp from the Dutch East Indies. He was also a director of Natura Artis Magistra, president of Felix Meritis, founder of a riding academy and Lieutenant Colonel for the National Guard artillery unit in Amsterdam. Mother Jonkvrouw Johanna Susanna (van der Does de Bye) Matthes [1851 - ?] was a descendent of Jan van der Does, who had led the resistance against the Spanish during the Siege of Leiden.
