Pennsylvania native Francis “Bill” Zettler received his doctorate from Cornell University. A resident of Alachua County for 45 years, he retired as professor emeritus from the University of Florida’s College of Agriculture in 2003. He has had a life-long interest in the subjects of biology and history. He was a faculty member for 37 years at the University of Florida before retiring in 2003, and has continued to teach on an ad hoc basis ever since then. One of his most popular courses was “Biohistory: Plants, Plagues, and People,” which he created in 1990. He is the recipient of several teaching awards, including UF’s Teacher of the Year Award. His training in biology and interest in local history were the impetus for The Biohistory of Alachua County and The Biohistory of Florida.
