Brother Donald Geiger
He found the students at Cathedral Latin to be receptive and generally hard-working. It was an outstanding experience. His teaching at Latin opened a career of teaching and conducting research in biology. He taught at the University of Dayton from 1964 to his retirement in 2008. He met up with former CL students Dominic Cataldo and Ron Konopka, who had done research projects at CL, in his classes in the Department of Biology at the University of Dayton.
He greatly enjoyed the classes at CL. A number of students did after-school projects. One student, Ron Kanopka became famous for his pioneering discovery of the PER gene that is a key gene in our biological clock. He died this year (2015) Bro, Geiger is professor emeritus in the Department of Biology at the University of Dayton, Dayton, Ohio. He is founder of the Marianist Environmental Education Center (MEEC) at Mt. St. John in Greene County, Ohio, a community in the Catholic tradition dedicated to restoring communities of land and people. As part of his sabbatical in 1992-93 he studied creation spirituality with Thomas Berry at Riverdale on the Hudson.
He taught courses in environmental plant biology, plant biology, ecological restoration and global environmental biology. His research and publications are in the areas of photosynthesis, carbon metabolism and transport in plants, the biology and management of bush honeysuckle, establishment and succession of tallgrass prairies and the mode of action of glyphosate (Roundup), its transport within plants, and effects on photosynthesis and carbon metabolism.
With the staff of MEEC, he is engaged in educating other communities to preserve and act in communion with the land. He is active in working with native and restored ecosystems, particularly at the Mt. St. John nature reserve and native plant resource center. Educational programs provide experience in prairie and wetland restoration and control of invasive species, particularly bush honeysuckle. He has contributed a number of articles to Restoration and Management Notes of the Society for Ecological Restoration and the Ohio Woodland Journal on these topics. Geiger has engaged in projects involving establishment restoration and enhancement of habitats at the Fernald Environmental Management site (a Manhattan atom bomb Project site) in Ross Ohio and at Creekside Reserve and the Xenia Prairies Reserve of the Greene County Parks. He and several students have developed management plans for 21 Nature Reserves of the Greene County Park District. He helped found the River’s Institute associated with the Fitz Center at the University of Dayton. In over a decade of its history he has recruited and helped develop numerous Rivers Stewards who are active in bringing persons to appreciate and use rivers.
He served as a trustee of the Beaver Creek Wetlands Association, Board Member of the Ohio Prairie Association, member of the B-W Greenways Association, the Society for Ecological Restoration, the Ohio SER and Wild Ones. Geiger has given numerous presentations on the topic of care for the land, faith-based stewardship, ecological restoration, bioregion awareness and green space preservation. He has taught in the Montgomery and Greene County Master Gardener Programs. He is a Fellow of the Ohio Academy of Science and recipient of the Environmental Education Award of the Ohio Alliance for the Environment. He retired from the Department of Biology at the University of Dayton in 2008 and is Professor Emeritus.
