His valet, George Jacobs, thought Frank “craved class” in women. Socially, no one could have been classier than the heiress Gloria Vanderbilt. Thirty-one when she and Frank got together in late 1954, she had come into a fortune — some $27 million in today’s dollars — and had for years been married to a man 42 years her senior, the conductor Leopold Stokowski. When Frank got word to Vanderbilt that he wanted to meet her, she recalled in 1988 in a journal-style memoir, she wanted to tell herself “Stop!” — but didn’t. Vanderbilt stepped out with Frank within days. Then she moved out of the sumptuous home she shared with Stokowski, taking their two small sons with her. After Christmas, having told the press her marriage was over, she arrived for a Broadway premiere on Frank’s arm. Yet, as Vanderbilt wrote in her journal, she could not “imagine a long tomorrow with F. and me in it”. The doubt was well founded, for their affair lasted only a few weeks.
