Who remembers Apple’s Lisa?

Who remembers Apple’s Lisa?

On January 19, 1983, the Apple Lisa was introduced, the first personal computer to offer a graphical user interface in an inexpensive machine aimed at individual business users.

Douglas Engelbart and the Computer Mouse

On November 17, 1962, U.S. American computer pioneer Douglas C. Engelbart has been granted a patent on the world’s first computer mouse.

Bill Gates – From Entrepreneur to Philantrop

On October 28, 1955 entrepreneur William Henry “Bill” Gates III, or simply Bill Gates, was born in Seattle, Washington.
