concepts were not acceptable. While Rey prepared to demonstrate that the analysis was incorrect, Wood took a different route and called Watson to inform him that IBM was about to make a mistake. However, the concepts were still sound. Shortly thereafter, IBM purchased Rey's invention and hired the unemployed high school teacher as a senior engineer in Endicott, New York. The test scoring machine, the IBM 805, was announced in 1937. Rey went on to a prolific career in Endicott, where he had fifty-three patents, mostly in the area he called input, before leaving for San Jose, California, in 1951.
Rey was approached that year with an offer, that was to change his life and work and to have a major impact on IBM and the computing world. He was asked to move to California to head a new laboratory where IBM would have a better chance to hire the engineers needed to move into the technical areas just being established and to provide closer contact with IBM's most innovative customers. Rey was given a charter to define his own programs so long as they did not duplicate the programs of others and he was expected to devote some of his efforts to adapting IBM machines to special customer needs. With Rey's background in data input, then mainly punched cards, programs were soon directed at means of automating the input function. The massive input data source he addressed was the punched-card tub file from which, for each transaction, cards were pulled identifying customer, inventory, pricing and so forth for subsequent punch card processing. The tub file was that eras' data source with random access to the data. Many configurations were addressed for machine access to stored data. They included magnetic data storage on rigid rotating disks, on drums, on tape strips, and on wires. Early in the life of the new lab, Rey became convinced that disks offered significant advantages over the other alternatives and, despite obvious unsolved problems, directed the laboratory in that direction. His belief in the inventive capabilities of his staff was rewarded when in a relatively short time, from present perspectives, air bearings were providing close spacings to rotating (and wobbling) disks, the electronics of read-write heads was taking shape, and the disk and its magnetic coating were in early definition. The new disk file was then defined
