An Wang

October 21, 1949

An Wang Filed a Patent for a Magnetic Ferrite Core Memory

An Wang called his patent "pulse transfer controlling devices." Computer designers had been looking for a way to record and read magnetically stored information without mechanical motion, and Wang's concept of the magnetic core memory was central to later computer development. Two years later An Wang found Wang Laboratories.
