the Lowie Museum at Berkeley. His time at Berkeley also included conducting flint knapping demonstrations for scholars and students and occasionally for museum visitors. After his battle with cancer was over in 1941 he worked for several months at the Lithic Laboratory of the Ohio Historical Society. It was during this period that Crabtree was called upon as an advisor in lithic studies to the University of Pennsylvania, where he was associated with Edgar B. Howard and the Clovis point type site at Black Water Draw. Frank H. H. Roberts of the Smithsonian Institution also called upon him around this time to consult on the analysis of the Lindenmeier Folsom point collection. When the U.S. entered into World War II the Lithic lab was discontinued and Crabtree returned to California to assist in the war effort as a coordination engineer for Bethlehem Steel Company, which built the ships for the Pacific effort until the war ended. After WWII he returned to Twin Springs, Idaho and became a successful real estate salesman in the postwar market. Crabtree was employed from 1952 until 1962 as a county supervisor for the U.S. Department of Agriculture's Agricultural Stabilization and Conservation Service (ASCS) in Twin Falls. In March 1962 he opened the First Conference of Western Archaeologists on Problems of Point Typology at the Idaho State College Museum with a demonstration of his flintworking skills. In 1964 he was appointed Research Associate in Lithic Technology at the Pocatello Museum - a job he maintained until 1975. Awards and honors Don Crabtree was awarded an honorary doctorate degree from the University of Idaho for his outstanding contributions to the field of experimental archeology. As a rule he was apprehensive to speak at lectures and publish his work therefore the majority of the archeological community did not realize the depth of his contributions until most of his papers were published in the Idaho State University Museum journal, Tebiwa. After this he became a household name in the U.S. and the "Crabtree School" of Flintknapping was begun during which he taught some 33 pupils from 1969 to 1975 many of which would produce dissertations that would educate students across the country in lithic technology. In 1969 some of Crabtree's work was featured in a special exhibition at New York's American Museum of Natural History. He is also credited with the creation of "Crabtree's Law" which is integral in
