I know I’m dating myself when I write this, but I vaguely remember Mr. Wizard as one of the Saturday shows that I would watch as a young kid. Even at age 5 or 6 I was fascinated with science, and Mr. Wizard showed me – and a generation of nerdy kids like me – what science was all about.
I even remember this image – it was a Rube Goldberg device that lit a candle by striking a falling match against sandpaper. The thing in the middle is a balloon, as I recall. I think the name of the boy on the left is “Timmy”.
He made science commonplace, science for the people. May he rest in peace.

That is so sad. I loved Mr. Wizard as a child. Haven’t thought about it in quite sometime, but brought back some fond memories of me and my grandmother on Saturday mornings.
Sigh. You just can’t find good television scientists these days. Unless you count the professor from Gilligan’s Island. And I can only see him on TV Land these days…
