Arrowsmith by Sinclair Lewis

John A. Robertshaw, John Aldington Robertshaw, professor of physiology in the medical school, was rather deaf, and he was the only teacher in the University of Winnemac who still wore mutton-chop whiskers. He came from Back Bay; he was proud of it and let you know about it. With three other Brahmins he formed in Mohalis a Boston colony which stood for sturdy sweetness and decorously shaded light. On all occasions he remarked, "When I was studying with Ludwig in Germany-" He was too absorbed in his own correctness to heed individual students, and Clif Clawson and the other young men technically known as "hell-raisers" looked forward to his lectures on physiology.

They were held in an amphitheater whose seats curved so far around that the lecturer could not see both ends at once, and while Dr. Robertshaw, continuing to drone about blood circulation, was peering to the right to find out who was making that outrageous sound like a motor horn, far over on the left Clif Clawson would rise and imitate him, with sawing arm and stroking of imaginary whiskers. Once Clif produced the masterpiece of throwing a brick into the sink beside the platform, just when Dr. Robertshaw was working up to his annual climax about the effects of brass bands on the intensity of the knee jerk.
