Arnold Sommerfeld was supposedly a great educator and a likeable teacher. From Wikipedia: “ He invited collaboration from them, and their ideas often influenced his own views in physics. He entertained them in his home and met with them in cafes before and after seminars and colloquia. Sommerfeld owned an alpine ski hut to which students were often invited for discussions of physics as demanding as the sport.” [1] Four of his doctoral and three of his post-doctoral students went on to become Nobel prize winners. That’s a lot of Nobel prize winners. [1] https://en.m.wikipedia.org/wiki/Arnold_Sommerfeld https://en.m.wikipedia.org/wiki/Arnold_Sommerfeld
