Good Evening, Chet and Laura,
I'm sorry to hear the news. I can't claim that I ever actually knew Chet, but I did meet him once, perhaps fifteen years ago, when Webster University opened an exhibit featuring stock work from Photographic Resources. At the time, I was selling a few photos through that agency as was Chet. I can only recall having a brief discussion with him about the equipment he was developing and trying to get on the market. He impressed me as innovative and hard-working.
