One master from my era at PSS ('55-'63) whom I remember with affection was Ernie Gladwell. I learnt some German and some of that strange dialect, Scientific German, from him.
I distnctly remember the first words of the first lesson from him: he held up one finger and said, loudly and clearly : "Finger!" (pronounced the German way, like 'singer'). There must have been a lot more afterwards, since I seem to know more German than that, but that's the lesson that stuck in memory.
That and the time when I hiccupped loudly and he told me to clear out before he knocked my block off. He seemed to think there was something insincere about the hiccup.
Oh, and the time he recommended the novel he'd just read: "Limbo '90", by Bernard Wolfe. I got the book from the library and was amazed to find it contained sex. (I can recommend it too: it's about a post-nuclear-holocaust America in which people voluntarily replace their limbs with robotic prosthetics. You'll have trouble finding it, though: the very first link turned up by Google is headed: 'Bernard Wolfe: A Forgotten Writer'.)
I haven't seen much mention of 'Ernie'. Does anyone else remember him? Does anyone know if he's alive and well?
