Did Gene Rayburn play the mad scientist host named Zachary or Zacharly on a kids horror show from 1950s?

Gene Rayburn was a popular television host, but he was not known for hosting a kid's horror show in the 1950s. He is most famous for hosting the game show "Match Game" from 1962-1973 and again from 1975-1982.

It's possible you're thinking of a different show or host. Could you provide more details about the show you're thinking of?

* What was the name of the show?

* What was the approximate year it aired?

* Can you describe any other details about the show or the character?

With more information, I might be able to help you identify the show and host.
