John/Rob,
Sorry to hear of your dads passing. Always enjoyed talking to him and working with him at Pratt. As I think back it seems as though he always had a smile on his face. One outstanding trait he had was that he always had his glasses pushed up onto his head. I still picture that as I think of my dealings with him..
My condolences you and your families, I’m sure he will be missed by all.
