Bob died suddenly Jan. 30, 2005, from a fall in his Morristown, N.J., home.
Born in Teaneck, N.J., he graduated from Morristown High School. At Princeton he was a mechanical engineering major and graduated with high honors. A member of Campus Club, Bob roomed with Clem Darby, Dick Freeman, and Lew Thompson.
Bob entered the nascent air-pollution control business with Pulverizing Machinery Co. in Summit, N.J., and established subsidiaries of the company in Europe, South Africa, and Australia. He later joined the Torit Co. in Minnesota, where he invented the cartridge dust collector, now the industry standard. Moving back to New Jersey, he was general manager of the Particle Processing Division of VibraScrew for several years before setting up Robert Frey Associates to market another invention, the PulseJet Screen, used for fine powder classification.
Active in the Episcopal church, Bob was a lay eucharistic minister at St. Paul's in Chatham and a member of the Cursillo Movement. He was a faithful contributor to Princeton, attending football games, mini-reunions, and every major class reunion.
The class offers its deepest sympathy to his wife of 52 years, Joan Whitney Frey; his children, Susan Omanson, Robyn St. Clair, and Douglas Frey; eight grandchildren; and his sister, Sara Malin.
