Following a tour of duty with the U.S. Navy, Weinacht returned to academic studies and received a Ph.D. in mathematics from the University of Maryland. A National Science Foundation post-doctoral appointment at New York University preceded his 45-year career at the University of Delaware, Department of Mathematical Sciences, from which he formally retired as professor. During his career, Weinacht also engaged in scholarly pursuits internationally with sabbaticals at the Technische Universität Darmstadt in Germany and the University of Rome and the University of Florence, Italy. Post-retirement, he continued to be active in research and teaching as an Emeritus Professor.
