He has served with distinction as Graduate Advisor (1960-1980) and Chairman (1972-80) of the Chemistry Department through the formative years. Although "Pritch" took an early retirement in 1991 after 33 years on the faculty, he continued to be active in the administrative and educational roles of the Department, serving as Vice-Chairman of the Department (1987-94). 

After he retired in 1991, he was recalled to assist with the construction of PSB North and renovation of the existing Chemistry building due to his expertise and knowledge about the department and their labs and equipment. He peacefully passed in July 2020 at the age of 88.
