Dear Mrs. Linda Kleindor: Just today, I found out about the departure of dear Professor George B. Kleindorfer. He was the best professor I had during my graduate studies at Penn State. He was a wonderful professor and a humble human being. As part of my doctoral committee, he was very helpful and supporting. I had a chance to visit him in 1996, along with my wife and children, and had a chance to see his barn and his horse. I will always remember him with great appreciation. Rest in peace.
