Catalog type History
Provenance From Clifton Technical Physics directions (annotations in brackets are Dr. Bowman’s handwritten comments): "Early in 1965 Bernard Clifton of Clifton Technical Physics was approached by Dr. Frederick Kalber of City College of New York who came to see us with a small two stage thermoelectric cooling module, a Wheatstone bridge and a variable power supply with which he was measuring freezing point depressions. Dr. Kalber asked whether we would make up two similar models for City College and for the Marine Research Laboratory of Duke University. We suggested that we should design and make up a stable compact temperature controller with a digital readout to drive a similar thermoelectric cooling module. This we proceeded to do. Only after we delivered our first two units did we discover that we had developed independently [After Dr. K had described the Science paper contents to Clifton] what was virtually a small solid state version of the device developed by Drs. Bowman and Prager at the National Heart Institute [Ref. Prager & Bowman, Science, October 1963]. " This instrument was used by Dr. John Buck, Bldg. 2, Rm 106.
