Glossy 8.5 x 11 photo of a diagram for Engelbart's luminous display patent issued in 1960, entitled "Luminous Display Device," signed across the bottom in black felt tip, "Doug Engelbart." In fine condition.
In 1955, Engelbart received his doctorate from UC Berkeley for a computer-technical thesis on gas plasma screens. Arising from his research in that area, this patent, essentially an early example of the now-ubiquitous flatscreen display, came at a time when most computer output came in the form of a paper printout, or-at best-a CRT display. It is another testament to Engelbart's technical skill and visionary foresight in the realm of personal computing.
From the collection of Bill Daul, a longtime friend and colleague of Douglas Engelbart.
