The Knight keyboard is designed by Tom Knight, was used with the MIT-AI lab's bitmapped display system. It was a precursor to the space-cadet keyboard.

Tom Knight is an American synthetic biologist and computer engineer, who was formerly a senior research scientist at the MIT Computer Science and Artificial Intelligence Laboratory, a part of the MIT School of Engineering.

In 1967 Knight wrote the original kernel for the ITS operating system, that ran on PDP-6 and PDP-10 computers.

In 1968, Knight designed and supervised the construction of the first PDP-10 ARPANET interfaces with Bob Metcalfe.

In 1972, Knight designed one of the first semiconductor memory-based bitmap displays…

In 1974, Knight designed and implemented the prototype version of the MIT Lisp Machine processor…
