Lewis Baum was an unhappy man.  The old building where he rented office space was set for demolition in June 1907, which just didn’t seem fair since he had a lease that ran through 1908.    So he did something that in retrospect seems a little crazy.  On the day that demolition started, he went to his office, or at least what was left of his office.  And for the next five days, he worked calmly from his desk, refusing to leave even as the walls crashed around him  and plaster rained down on his head.
