Some things are so common one doesn’t connect them to any one person or source. The computer mouse is one such thing, and its inventor, Douglas Engelbart died today, July 3, 2013, at age 88.

I don’t know how to think about that. Sad, of course, but grateful there are men and women who have the imagination to create such useful tools. I mean, what a tedious thing using a computer must have been without the mouse. People actually did that? Unimaginable!

Until you died, Douglas Engelbart, you didn’t exist for me, yet now I feel you are among the great people of all time. RIP. Thank you! You are, too late, one of my heroes.
