Buck, a colleague of Dr. Widrow, was developing methods to make memistors in the laboratory at M.I.T. (Dr. Widrow was not aware of this.) Dr. Buck's larger view was developing methods to manufacture integrated circuits with electron beams. He was particularly interested in manufacturing cryotron computers. He was also interested in the work of Frank Rosenblatt and the perceptron (a self-learning computer). For the self organizing systems of the day, they were only interested in analogue memory devices. Transistors were still very expensive and just beginning to achieve some level of reliability, and the tube... well.. they were tubes. Some of Dr. Buck's earliest experiments for making memistors were with growing tin dendrites in an electrolyte. Soon after he considered anodizing one of two plates of aluminum, the amound of anodizing being the stored value. Cuprous Sulfide was attractive in that copper could be plated out of Cu2S. The term memister was not in use, Dr. Buck called his device a "synapse", using a copper sulfate / copper iodide device enclosed in a cylinder of quartz. In the summer of 1958, Dr. Dudley A.
