Robert Schuellein left the University of Dayton for the National Institutes of Health in 1963. But he never forgot UD and the legacy he started here: With his faculty colleague and fellow Marianist Paul Machowicz ’41, Schuellein helped create the first master’s program in the College of Arts and Sciences. When Schuellein died in 2011 at the age of 91, he added to that legacy — with a bequest totaling $2.5 million for a faculty research endowment in biology.
