We are sorry to report the death on Feb. 3, 2005 of long-time CSA member Dr. Francis (Frank) Zimmermann. Frank earned the degree of ScD from MIT under Sam Collins in 1953. His dissertation was concerned with the adiabatic demagnetization of paramagnetic salts in liquid Helium2. He worked in cryogenics at Arthur D. Little and Oak Ridge for several years before accepting a teaching position in the engineering school at Yale. In 1962 he moved to Lafayette College, in Easton PA, where he was a professor in the ME department until retiring in 1986. He was a cryogenics consultant to Air Products and Chemicals during his tenure at Lafayette.
