He came to Princeton from Hamilton (N.Y.) Central High School, where he was active in band and publications.  

At Princeton he majored in mechanical engineering and was a member of Cloister Inn, played interclub hockey, and was secretary-treasurer of the American Society of Mechanical Engineers student branch. He roomed with Dave Dantzscher, Owen Terry, and Dick Thompson. His father was a member in the Class of 1929. 

After graduation Harry did graduate work at Syracuse University and then worked on the Apollo moon project as a project engineer, helping to develop cutting-edge technology for rocket flight, moon landing, and takeoff. In 1962 he married Janna Peterson, and they moved to Lincoln, Mass., in 1968. 

In 1975, he bought a company that manufactured dust-collecting equipment. Harry expanded the company to include design, manufacture, and installation of the dust-collection systems. At the request of the Massachusetts DEP, he developed a system for removing particulate and fumes from medical waste incineration and was awarded a process patent for his invention. After 25 years, he sold the company and retired. 

Harry is survived by his wife, Janna; son, Rick; daughter, Jannette.; and grandson Henry. The class extends its deepest sympathy to them all.
