Mr. Wizard!
Don Hubert, better known as "Mr. Wizard" has gone to the great science class in the great beyond. Ironically, I had never heard of him until I saw the classic Jim Henson series "Dinosaurs" which had a little show called "Meet Mr. Lizard" which had the famous line "We're going to need another Timmy" after the experiment wiped out his assistant Timmy". Also, he was quickly mentioned in passing with the movie "The Matrix", as Neo screams into the phone "Mr. Wizard! Get me outta here!"
