“COLLECTING” IS PART OF our DNA. From earliest times, we have collected food, clothing, and shelter to survive. But once those basics are met, we look around and find something new and glitzy to make our hearts beat faster. Marjorie Merriweather Post (1887-1973) was a preeminent 20th century collector. She grew up in wealth and turned that into a megafortune as CEO of General Foods, notably embracing the new idea of “frozen foods” in the 1920s.  With her fortune secured, she next decided to build a life that would make her happy.
