TV Science Guru "Mr. Wizard" Dies at 89

Don Herbert -- TV's favorite science teacher who taught kids to try everything at home -- died yesterday at 89 in Bell Canyon, Calif.

In the earliest days of TV, Herbert turned the idiot box into a science classroom that every child -- and plenty of adults -- could love and learn from. "Watch Mr. Wizard" ran from 1951 to 1964, but Mr. Wizard lived on well beyond that, through the 1980s, when "Mr. Wizard's World" ran on Nickelodeon. "The show today might seem slow, but it was in-depth and forced you to think along," said Steve Jacobs, a former on-air sidekick, to the AP. Herbert was also one of the first guests on David Letterman's NBC show.
