Ever since his medical school days at the University of Minnesota in the 1940s, John R. Pfrommer has believed that public health just makes sense.
Pfrommer remembers listening to Hubert Humphrey, then mayor of Minneapolis, talk on the radio about President Harry Truman’s ideas for a national health program.
“It seemed eminently sensible,” Pfrommer says. So a few years after he finished his medical training—he specialized in preventive medicine—Pfrommer also decided to get a master of public health (M.P.H.) degree.
