Geoff passed at 83 yesterday due to complications from pneumonia.
Best known for "Treasure Hunt", which he hosted for eight years; a new generation knew him as the host of the arcade game show "Starcade" in the early '80s (with recent reruns on G4 when that channel launched).
Also hosted two of the three versions of "Jackpot!", the '90s remake of "Chain Reaction" and a slew of others (plus appeared as a regular on "The Bobby Darin Show" in 1973), but his news and radio careers are just as impressive - as a young reporter, he was on-scene when Lee Harvey Oswald was shot. he had been working as a travel writer most recently.
I can't say I met Geoff, but I was on a conference call with him once, and I was FB friends with him for a long time. He was a wonderful guy.
