Don Herbert, a.k.a. Mr. Wizard, was the first guy to host a kid's TV show all about science. He was basically the Bill Nye the Science Guy of the black and white era. He also had a revival on Nickelodeon that some of you might remember.
I think I recall reading a few years back that a toy company wanted to release a retro Mr. Wizard Chemistry Set based upon the ones sold back in the 60's, but it turned out that most of the contents of the original were no longer legal to sell to the general public.
