Edith Rockefeller McCormick, the daughter of John D. Rockefeller, maintained a large household staff. She applied one rule to every servant without exception: they were not permitted to speak to her. The rule was broken only once, when word arrived at the familys country retreat that their young son had died of scarlet fever. The McCormicks were hosting a dinner party, but following a discussion in the servants quarters it was decided that Mrs. McCormick needed to know right away. When the tragic news was whispered to her, she merely nodded her head and the party continued without interruption.
