April 6, 2014 (HP74).  Our readers interested in history of superconducting electronics may wish to read the recent IEEE Spectrum popular article by David C. Brock on Dudley Buck, the prematurely departed inventor of the cryotron, cryotron logic gates and first proponent of the cryotron computer, back in 1950s.  That article contains many little known details from Buck’s life and activity including his cryotron research at Lincoln Labs and efforts towards micro-miniaturization of cryotron devices and circuits.   Information on consequences of his research, the various computer projects at other organizations and industrial laboratories including that of IBM, all triggered by Buck’s ideas, is also provided.  Spectrum posted this article online on March 19, 2014. The link to the article is: http://spectrum.ieee.org/computing/hardware/dudley-bucks-forgotten-cryotron-computer. In it is included a link to Buck’s original Lincoln Labs internal memorandum on the cryotron concept.
