Schumpeter: "let us begin"
David Rockefeller remembers Schumpeter's arrival to teach a graduate level class:
(p. 79) Arriving in class with an air of being in a great hurry, he would throw his overcoat on a chair, whip his handkerchief' from his pocket, flip it out toward the room, then fold it and carefully mop his brow and the top of his balding head before saying, in his heavy German accent, "Ladies and gentlemen, let us begin."
