Angeline Myra Keen (1905-1986), an invertebrate paleontologist and malacologist, was an international expert on the systematics of marine mollusks. She influenced her profession as a researcher and fieldworker, teacher and advisor, curator and exhibitor, author and public speaker. Her work was of interest both to academic scholars and to shell collectors.
Raised in Colorado, Keen became an amateur naturalist and photographer in her teens, and pursued her research interests in birds and insects at Colorado College, graduating with an A.B. in 1930. She earned an M.A. in psychology from Stanford University the following year, and then a doctorate in psychology from the University of California at Berkeley. Finding herself with no employment prospects, graduating in the depression year of 1934, she volunteered to help identify shells in the Stanford geology department's collection. This was the beginning of Keen's serious study of shells and her thirty-eight year association with Stanford. She had some coursework in biology, geology, and statistics, but was self-taught in malacology.
In 1936 Keen was appointed Curator of paleontology in the department of geology, and began teaching there during the Second World War. She was appointed Assistant Professor of paleontology in 1954 and Curator of malacology in 1957. Despite her stature, Keen waited until 1960 for appointment as a tenured Associate Professor and until 1965 for a full professorship, becoming one of three women professors in the sciences at Stanford. Upon her retirement in 1970, she was made Professor of Paleontology Emeritus and Curator of Malacology Emeritus, and taught two more years.
Keen's research focused on molluscan systematics, but ranged widely within the field to include recent marine mollusk fauna of the Panamic Province and marine molluscan Cenozoic paleontology, neontology, and zoogeography of western North America. Keen was particularly interested in bivalve systematics and nomenclature. She spent many years adding to, cataloging, and systematically arranging the Cenozoic mollusk collection at Stanford. She also wrote fourteen books and sixty-four papers in the field of malacology.
Keen was the primary teacher of students in malacology at Stanford, advising advanced degree candidates in geology and biology. She also taught courses in advanced paleontology, biological oceanography, and curatorial methods.
Keen's professional honors included Phi Beta Kappa, a 1964 Guggenheim Fellowship, and appointment as Fellow of the Geological Society of America and as fellow of the Paleontological Society. She received the Fellows Medal from the California Academy of Sciences in 1979, becoming the first woman to do so. She served as President of both the American Malacological Union and the Western Society for Malacology, and chaired the Committee on Nomenclature of the Society of Systematic Zoology.
