Hydrobiologia 180: IX-X, 1989. J. L. Kaster (ed.) Aquatic Oligochaete Biology IX Dr. Clarence James Goodnight A.B., A.M., Ph.D. In Memoriam Dr. C. J. Goodnight, born May 30, 1914 in Gillespie, Illinois, died on August 9, 1987. Dr. Goodnight taught at Brooklyn College, New York City, Purdue University and Western Michigan University, Kalamazoo. He was widely travelled, and was associated with many Universities and laboratories. His list of positions with major scientific societies included the posts of Secretary to the North American (then Midwest) Benthological Society, President of the American Microscopical Society, and Secretary, American Society of Zoologists. Dr. Goodnight one of the first American scientists to contribute to the study of aquatic oligochaetes in relation to pollution, beginning with his key to the group in the 1959 revision of Ward and Whipple. His list of grants and publications indicates a rapid shift from the study of pollution indicators in the early 1960s to an interest in the accumulation of radionuclides by tubificids. This was added to his much earlier interest in the Branchiobdellida, which resulted in publications dating from 1939-1943. His pollution studies, often in association with graduate students, broke new ground and it is quite usual to find his name among the first to publish in each phase of aquatic oligochaete biological work in North America. This is evidenced still in his later papers on spermatogenesis in Limnodrilus, identifying two sperm types and recognizing the effects of phagocytes in the sperm sac. X Dr. Goodnight made a very significant contribution to the study of aquatic oligochaetes and provided one of the very few centers for the training of graduate students in our field at a significant period in its development. He would have surely contributed to these Proceedings of the first of our meetings to be held in the United States, and this volume is dedicated to his memory.
