Jim Gray!
I had the luck to work with Jim a couple of years and can tell, he was the person you can read in this and other articles. And more, our kids were always welcome to his (small) office, he always had papers, pencils and TIME for them. They still remember him after many years. We stayed in contact after going to separate companies but I definitely will miss his Xmas greetings every year and his always nice and immediate answers when I did ask anything, mostly stupid questions. I'm sure that many other besides me did learn that being technically good (not brilliant as Jim) is not good enough, you also have to be a human who understands others.
