His supposed remark when meeting another leading physicist, Paul Ehrenfest, illustrates this notion of an arrogant Pauli. The two met at a conference for the first time. Ehrenfest was familiar with Pauli's papers and quite impressed with them. After a few minutes of conversation, Ehrenfest remarked, "I think I like your Encyclopedia article relativity theory better than I like you," to which Pauli retorted, "That's strange. With me, regarding you, it is just the opposite." The two became very good friends from then on.
