I never met him, but he definitely had a big impact on my life. Like so many I was first exposed to computer programming through Microsoft BASIC. These days I make a living working as an engineer at one of his philanthropies. But what I will maybe remember most is a weekly invitation he extended to come to his pool, where I have helped teach my wife to swim in a relaxing environment. His family and friends I am sure will be sad, but his impact lives on today.
