Wink Martindale. NYT (archived).
Martindale said he became interested in hosting a TV game show in 1965 when he learned that Password‘s Allen Ludden would “go in two days a week and tape five shows one day and five shows the next and the other five days play golf. I went to my agent and said, ‘How about sending me on a game-show hosting interview?’”
He eventually landed at NBC’s What’s That Song? (billed as Win Martindale) and worked for a year on that, the first of the 20 game shows that he hosted (only Bill Cullen did more). He was on Tic-Tac-Dough for a decade, did two shows for producer Chuck Barris (How’s Your Mother-in-Law? and Dream Girl of ’67) and produced game shows as well.
Another one that would have got past me if it wasn’t for “The Rap Sheet” (and I haven’t seen an obit anywhere else): Peter Lovesey, one of the great British crime writers.

He was also one of the world’s leading track and field statisticians.
Interesting, as his first novel (which was re-issued in a 50th anniversary edition late last year), Wobble To Death, is a Victorian era murder mystery…set against a speed walking marathon.
