SPRING 1 992 / Center for Urban Horticulture / Washington Park Arboretum / College of Forest Resources / University of Washington / Vol. 9, No. 2 U CENTER NEWS What a winter! Or rather— was it winter? As we go to press on this last day of January, the usual winter rains are just now arriving, and already some bulbs threaten to burst into bloom. Hopefully, spring will not trick us and turn to winter. Bring on spring! Also, please notice that we are now pro- ducing this newsletter on recycled paper. We hope you appreciate the change! Directorship Resignation Dr. Harold B. Tukey, Jr., Director of the Center for Urban Horticulture and Arbo- reta, announced his resignation from these directorship duties effective De- cember 31, 1991. Dr. Tukey came to Seattle in May, 1980. He was previously a professor of ornamental horticulture and plant physiology at Cornell Univer- sity. During his twelve years of tenure, Dr. Tukey supervised the physical develop- ment of the Union Bay headquarters site as well as the programmatic recruitment of faculty and staff for the university at both Union Bay and the Washington Park Arboretum. Developed with over 7.5 million dollars from both donors and support organizations, the Center was the first facility of its kind. Several similar centers are now under development around the world, using CUH as their model. Under Dr. Tukey's leadership, R. D. Merrill Hall was completed in April, 1984. This was soon followed by the Conference Hall (1985) — recently re- named the Northwest Horticultural Hall, Martha Lindberg Isaacson Hall (1986), Douglas Research Conservatory (1989), and the Elisabeth Carey Miller Library • addition (1990). The Donald G. Graham Visitors Center was opened in Washing- ton Park Arboretum in April, 1986. The Center for Urban Horticulture is committed to excellence in research, teaching and public service in urban horticulture. Dr. Tukey is currently enjoying a well- deserved sabbatical, and will return as professor of urban horticulture in Sep- tember, 1992. We wish him well and thank him for his role in developing this renowned institution. Acting Director Named On January 6, 1992, Dean David B. Thorud named Clement W. Hamilton, associate professor of horticultural tax- onomy, as Acting Director of CUH. Dr. Hamilton joined the Center faculty in 1985, and has been instrumental in pro- viding leadership in the development of the Otis Douglas Hyde Hortorium, and graduate and undergraduate curricula. A native of Ohio, Dr. Hamilton received his B.S. and M.A. from Harvard, and his Ph.D. in population biology from Wash- ington University (St. Louis) in 1985. He will serve as Acting Director until a per- manent director is named. We congratu- late Dr. Hamilton and wish him well in this new leadership role. Review In May, 1991, Dean David B. Thorud, College of Forest Resources, appointed a committee to conduct an academic re- view of the Center, following the guide- lines of the faculty code of the University. This committee was comprised of Arthur R. M. Nowell, oceanography, chair; Thomas Hinkley, forest resources; John A. Wott, urban horticulture. The report, published in December, 1991, is advi- sory to the Dean. Presently various units are discussing its implications. Faculty Appointments r Three faculty holding joint appointments with the Forest Resources Management Division in the College of Forest Re- sources recently joined the Center as vot- ing members. These new faculty are Thomas Hinkley, forest resources; Robert Gara, forest entomology; and Gordon Bradley, urban forestry and land use planning.
