This person invented the computer mouse in the early 1960s in his research lab at Stanford Research Institute (now SRI International). The first prototype was built in 1964, the patent application for this "X-Y position indicator for a display system" was filed in 1967, and US Patent 3,541,541 was awarded in 1970. The mouse remains to this day the most efficient hands on pointing device available. http://www.dougengelbart.org/firsts/mouse.html
