Yehuda Leo Picard (born June 3, 1900 in Wangen am Untersee , † April 4, 1997 in Kibbutz Ginegar ) was a German-Israeli geologist .

Life

Picard attended the Oberrealschule Konstanz, received his doctorate in 1923 at the Albert-Ludwigs-Universität Freiburg , emigrated to Palestine in 1924 as part of the Zionist movement and was an assistant at the Hebrew University of Jerusalem from 1925 to 1933 , where he founded the Faculty of Geology, which he had to build up from the smallest of beginnings and initially with few resources. In 1930 he received the Dr. Sci. at the University of London, became a lecturer in 1934 and professor of geology in Jerusalem in 1937. 1950 to 1954 he was director of the Geological Survey in Israel.

He dealt in particular with the geology and especially the hydrogeology of Israel (and was also active in this field as an international consultant in Africa and South America within the framework of UNESCO) and dealt with the rift tectonics at the Dead Sea . The latter already happened in connection with his geological explorations of the area around Jericho , published in 1931 (Geological researches in the Judean Desert). The well-known geologist John Walter Gregory (1864–1932) wrote an appreciative foreword because Picard supported the thesis advocated by Gregory, Eduard Suess and others that the rift valley along the Jordan Valley was caused by expansion of the earth's crust, while in 1928 the geologist Bailey Willis (1857– 1949) argued that the highlanders to the right and left of the rift valley had been raised.

In 1958 he received the Israel Prize . 1951 to 1953 he was the first president of the Israeli Geological Society.
