Shortly after my son started college, the president of the university had an assembly for the new students. "Welcome to Johns Hopkins," he began. "And please note that it's Johns, not John." Then he told how one of his predecessors, Milton Eisenhower, had been invited to talk at the University of Pittsburgh. After he was introduced as the president of "John Hopkins," Eisenhower said, "Thank you. It's great to be in Pittburgh."
