It happened frequently. The door of my office would be closed, and I'm would be quietly working or engaged in conversation with someone when suddenly the door would open, and a lean, dignified, rather tall American of German descent—then in his 90's— would come marching in, having done an "end run" around the receptionist and my assistant, much as a defensive tackle would do in breaking through the line of scrimmage in a football game. In his hand would be a magazine article or something encouraging which he wanted me to have. He stayed for only a few brief moments. Then he was gone, often reminding me of Elijah who appeared unannounced in the court of King Ahab.
