WCSA - On This Day – November 17, 2022 – Douglas Carl Engelbart received patent of computer mouse in 1970


(Worldkings.org) He never received any royalties for the invention of the mouse.

Douglas Carl Engelbart (January 30, 1925 – July 2, 2013) was an engineer and inventor, and an early computer and Internet pioneer.

Engelbart was born in Portland, Oregon, on January 30, 1925, to Carl Louis Engelbart and Gladys Charlotte Amelia Munson Engelbart. His ancestors were of German, Swedish and Norwegian descent.

He is best known for his work on founding the field of human–computer interaction, particularly while at his Augmentation Research Center Lab in SRI International, which resulted in creation of the computer mouse, and the development of hypertext, networked computers, and precursors to graphical user interfaces.

Engelbart applied for a patent in 1967 and received it in 1970, for the wooden shell with two metal wheels (computer mouse – U.S. Patent 3,541,541), which he had developed with Bill English, his lead engineer, sometime before 1965. In the patent application it is described as an "X-Y position indicator for a display system". Engelbart later revealed that it was nicknamed the "mouse" because the tail came out the end. His group also called the on-screen cursor a "bug", but this term was not widely adopted.

He never received any royalties for the invention of the mouse. During an interview, he said "SRI patented the mouse, but they really had no idea of its value. Some years later it was learned that they had licensed it to Apple Computer for something like $40,000."
