Memorial to Chauncey Glenn Tillman 1924-1982

W. D. LOWRY Department o f Geological Sciences, Virginia Polytechnic Institute and State University, Blacksburg, Virginia 24061 Chauncey G. (Jake) Tillman died in Blacksburg. Vir ginia, on May 7, 1982. after a heart attack. A memorial service, which was held May 10 in the chapel of the Virginia Tech War Memorial, was attended by several hundred students, faculty colleagues, and friends. I wish I had been asked earlier to write this memorial to Jake, for he was a close friend and colleague and was highly regarded by all his fellow colleagues in the Department of Geological Sciences of Virginia Tech. Jake joined the faculty of Virginia Tech in 1957 after the completion of his dissertation in paleontology at Harvard University under Dr. Harry B. Whittington. Jake’s promotion to full professor in 1968 resulted from his excellent teaching of invertebrate paleontol ogy on the undergraduate level and biostratigraphv and micropaleontology on the graduate level, from his very scholarly research, from his thoughtful guidance and counseling of undergraduates, and from the high stan dards he set for his graduate students. Jake was born June 8, 1924. in Detroit. Michigan, where he attended public schools. He entered Wayne State University in the fall of 1941 and attended one semester before being drafted into the army. He served three years in the European theater. After his discharge, he attended Michigan State University for one quarter before transferring to the University of Michigan, from which he obtained a B.S. degree in geology in 1950. That year he began working for the Mineral Deposits Branch of the U.S. Geological Survey on their Phosphate and Uranium Project out of Plant City. Florida. There he met Joan Barclay Pratt, and they were married on September 8. 1951. In 1952 he completed work on his M.S. degree in geology at the University of Michigan. He and Joan then moved to Reno. Nevada, where he worked on the Geological Survey’s Nevada Iron Resources Project for four months. From 1952 to 1954 he worked with the Survey’s Defense Minerals Exploration Administration in Salt Lake City. Utah, mainly on uranium mine exploration and evaluation in the San Rafael Swell-Moab area. Jake’s work for the Geological Survey was largely field work that kept him away from home much of the time, and I suspect that his decision to pursue a Ph.D. degree in paleontology at Harvard was to assure him of more time with his wife. Surprisingly, Jake had not had a course in undergraduate biology when he began his studies at Harvard. For his friends in paleontology, it may be somewhat of a surprise to learn that Jake had not planned to work under Dr. Whittington Joan relates that they ran into him on the campus before school started and that he and Jake sat down on the steps of a nearby building and talked for nearly two hours. Jake was then convinced he wanted to study under Dr. Whittington. As his friends and colleagues know. Jake certainly was not effu sive unless the subject was dear to his heart. Then he would talk enthusiastically and very articulately. Jake really enjoyed going to the field, and I remember so well when he and I 2 THE GEOLOGICAL SOCIETY OF AMERICA were returning from a field trip to the Shenandoah Valley with a graduate student, he talked most of the way home on Appalachian geology, a subject dear to his heart. Much of Jake’s research and that of his graduate students dealt with the biostratigraphy of Paleozoic formations in Virginia. In later years, he became keenly interested in the bio stratigraphy of Middle Ordovician limestones of Virginia and the unconformity between them and Lower Ordovician carbonates. After his recovery from an earlier heart attack on November 20. 1969, I got to know Jake well as I helped him measure and collect samples from sections of Middle Ordovician limestones. I valued his scholarly ways, and he served on many of my graduate students’ committees. His and many of his graduate students’ research involved the careful measurement, description, and close sampling of Middle Ordovician limestone sections. Their studies involved the recovery of conodonts. which are so well documented in his students’ theses and dissertations. In a letter to me. Dr. Stig M. Bergstrom of Ohio State University, who did the pioneer research on Middle Ordovician conodonts of Tennessee, praised the research of Jake and his students. He plans to prepare a joint paper, with Jake as senior author, that will incorporate the results of the research done by Jake and his students on Middle Ordovician limestones. Jake contributed much to the growing reputation of the Virginia Tech Department of Geological Sciences. He served on numerous department committees and those of the College of Arts and Sciences. He served as the local chairman of the meeting of the Southeastern Section of the Geological Society of America held in Roanoke in 1963. which featured a symposium on “Tectonics of the Southern Appalachians.” Again in 1979, Jake, as a member of the Technical Program Committee of the meeting of the Southeastern Section held in Blacksburg, gave yeoman service. He was cochairman of the Pander Society’s Conodont Symposium held in conjunction with the meeting of the North-Central Section of the Geological Society of America at Kent State University in 1974. Jake was elected a Fellow of the Geological Society of America in 1967. was a member of the Paleontological Society, the Paleontological Association (London), the American Association for Advancement of Science, and the Society of Sigma Xi. He was a participant in the American Geological Institute’s Summer Field Institute held in the British Isles in 1961 and sponsored by the National Science Foundation. He was proud of his College of Arts and Sciences Teaching Excellence Awards received in 1977 and 1978. Some of his research papers are given in the Selected Bibliography. Jake loved his family and was proud of his children. Their first daughter, Janet Barclay, was born July 26. 1957, only four weeks before they came to Blacksburg. She now lives in Chicago and works for the Social Security System. Their son. David Stewart, was born February 22, 1959. and is with the Johns Hopkins University Applied Physics Laboratory in Columbia. Maryland. Their second daughter. Barbara Cameron, was born June 8, 1962, and has just been awarded a four-year Air Force Scholarship and will enter the University of Virginia Medical School in the fall of 1984. Jake’s wife. Joan, still resides in Blacksburg and enjoys teaching mathematics in nearby Christiansburg High School. Jake is also survived by two brothers. John and Otto. Although sorely missed by his family and colleagues in the Department of Geologi cal Sciences, we are all appreciative of the many fine years we were permitted to spend with Jake after his first serious heart attack in 1969. A special fund was established in 1982 by the Virginia Tech Department of Geologi cal Sciences in memory of Professor Tillman. Interest from the fund is being used to give two awards each year to outstanding graduate teaching assistants, one for upper-division MEMORIAL TO CHAUNCEY Gl.ENN TILLMAN 3 teaching and one for lower. Each award is for $250 plus a copy of the American Geological Institute’s Glossary of Geology and Related Sciences. This C. G. Tillman Award for Outstanding Teaching Performance by a Graduate Teaching Assistant is a fitting tribute to an outstanding scholar and teacher.
