McDonald Edward Wrenn Jr. ’58

Ed died Dec. 19, 2002, after a long battle with cancer.

Ed entered Princeton from Woodberry Forest School on an NROTC scholarship, participated on the varsity soccer team, joined Key and Seal Club, and graduated with honors in physics. Serving three years as a naval officer, Ed was assigned to train some of the first nuclear-emergency teams.

After receiving a PhD from New York University's Engineering/Environmental Health program, Ed became a tenured professor of environmental medicine at NYU's Medical Center and pursued teaching and research. Ed would say that his area of specialty "was not so much sick people as sick environments."

From 1980 on he held two positions with the University of Utah, as director of the radiobiology laboratory and director of the environmental radiation/toxicology laboratory, becoming an international expert on the biological effects of internally deposited radioactive material. He authored some 100 scientific journal publications and contributed to 16 books in his field. For most of his life, Ed was an avid skier and tennis player, and coached several youth soccer teams.

The class sends its deepest sympathy to his wife, Elizabeth, and his sons Ed III and Edmund Tyler from Ed's previous marriage to Marie Claude Wrenn.
