"Sebastian Finsterwalder (1861\u20131951) was a German mathematician and glaciologist. Acknowledged as the \u201Cfather of glacier photogrammetry\u201C; he pioneered the use of repeat photography as a temporal surveying instrument in measurement of the geology and structure of the Alps and their glacier flows. The measurement techniques he developed and the data he produced are still in use to discover evidence for climate change."@en . . . . "1862-10-04Z"^^ . .
