If you are a computer user, you must be familiar with a Mouse, but wonder who did invent this little very useful pointing device?
Well, Douglas Carl Engelbart was the inventor of a computer mouse. He also contributed to the early incarnation of email, internet and word processing programs. The mouse at that time was a wooden shell covering two metal wheels that worked on X-Y position indicator logic for a computer display system.
He developed the mouse in 1960s while at his Augmentation Research Center Lab in SRI International and the mouse was patented in 1970 by SRI and later licensed to Apple. Apple released the first commercial product based on his invention with the Lisa Computer in 1983.
He was born on January 30, 1925 in Portland and studied electrical engineering at Oregon State University. He first worked with army as radar technician during Word War II and later joined Nasa's predecessor, NACA, as an electrical engineer. He soon left this job to pursue a doctorate at University of California, Berkeley. He also contributed in the development of ARPANet which later led to the Internet. He died on 3 July 2013 at the age of 88 years due to the Kidney failure.
