HEINZ A. LOWENSTAM (1912-1993) INTERVIEWED BY Heidi Aspaturian June 21-August 2, 1988 ARCHIVES CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California Subject area Geology, geobiology Abstract Interview conducted in eight sessions in the summer of 1988 with Heinz A. Lowenstam, professor of paleoecology. Dr. Lowenstam was born in Germany and educated at the universities of Frankfurt and Munich. He emigrated to the United States in 1937 to continue his graduate studies in geology and paleontology at the University of Chicago, receiving the PhD there in 1939. After a stint at the Illinois State Museum, he joined the Chicago faculty in 1948, working with Harold C. Urey on paleotemperatures. He joined Caltech’s Geology Division in 1952 as a professor of paleoecology, pursuing research in a variety of fields. In 1962, he identified iron in chiton teeth, the first known instance of biomineralization, later found in such diverse creatures as bacteria, honeybees, and birds. In this interview, he recalls the difficulties he faced as a Jew in Nazi Germany, his graduate work in Palestine in the mid-1930s, his life as an émigré, his investigation of Silurian fossils in the Chicago area, and his interaction with such mentors and colleagues at Chicago as Urey, N. L. Bowen, Bailey Willis, Bryan Patterson, and Karl Schmidt. He discusses the evolution of the Geology Division at Caltech; its important move, under division chairman Robert P. Sharp, into geochemistry in the early 1950s; his work on the http://resolver.caltech.edu/CaltechOH:OH_Lowenstam_H paleoecology of marine organisms; his recollections of Caltech colleagues, including Sam Epstein, Beno Gutenberg, Hugo Benioff, James Westphal, Max Delbruck, and George Rossman; and the changes that took place in the division over the decades since his arrival.

LOWENSTAM Session 1 1-19 Birth and early years in Upper Silesia, then part of Germany. Early education and elementary school. Jewish cultural influences. Early interest in minerals and fossils. Memories of World War I; impact of postwar depression and inflation on family. Decision to pursue career in paleontology. Partitioning of Upper Silesia betwen Germany and Poland; family moves into German part. Rise of Nazis. First year in invertebrate paleontology program at University of Frankfurt; leaving Frankfurt for University of Munich. Trips to Mussolini’s Italy and Poland in early 1930s. Session 2 20-33 Enrollment in University of Munich, 1933: Professors F. Broili and E. Dacqué; Dacqué’s role as mentor and major influence. Atmosphere in Munich in the 1930s. Recollections of K. von Frisch. Academic life at Munich: traditional faculty disdain for students. Growing interest in paleoecology; attempt to transfer from Munich to Berlin fails. Politics in Munich in 1933. Impact of Nazis’ rise to power on Munich geology department. Deteriorating political and social situation for Jews in Upper Silesia. Step-grandfather hounded by Nazis to renounce his conversion to Judaism and divorce his Jewish wife (Lowenstam’s maternal grandmother); grandparents commit suicide. Decision to write his PhD thesis on geology of Palestine. Dacqué’s advice to write thesis on geology of a particular area. Meets future (first) wife. Recollections of friends and colleagues who left Germany in 1933 and 1934. Session 3 34-53 Departure for Palestine in 1935. Association with Hebrew University. Thesis project on geology of E.
