Harry died June 24, 2020, in Lincoln, Mass. He was 83. 

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.
