Agree with the Freeper who suggested Barbara Olson. I will add my grandfather who died of asbestos related cancer (same type as what killed Steve McQueen) at age 75 in 1984.
Maybe it is not a person, but I wonder if the large archive of videotapes and film cans that NBC had by about 1975 or thereabouts and was chucked and destroyed for the most part on the orders of some silly woman who was in charge of programming there at that time could be included here. The colour videotapes of the 1960s Match Game and other game shows, variety programming, soap operas, and other things that featured early appearances by actors and actresses who were later famous and other precious curiosities likely should have been saved.
I think of Barbara Olson often and the devastating day she was taken from all of us. Very sad.
Another person I would choose is John Bonham. Enough said..
The third one is the one that haunts me most. I would choose HELEN THOMAS. I would love to see the look on that ogre’s face as D.C. has its Day of Reckoning. Just to see her gnash and wail
