Premise: Marjorie Merriweather Post (March 15, 1887 – September 12, 1973) was a leading American socialite and the owner of General Foods, Inc. She used much of her fortune to collect art, particularly pre-revolutionary Russian art, much of which is now on display at Hillwood, the museum that was her estate. She is also known for building Mar-a-Lago, an estate now owned by Donald Trump.
Hypothesis: Marjorie Merriweather Post is a billionaire.
