There are galleries – and there are galleries. Peggy Guggenheim’s Art of This Century wasn’t your average display space. It had curving gumwood walls, turquoise floors, amoeboid furniture and bizarre mechanical contraptions. It was the product of one of New York’s more notorious socialites (Peggy was renowned for her free-love ways) and a rotating cast of architects, surrealists, poets, artists, oddball curators and thinkers.

Though initially intended as a platform to show the works of her European artist friends, Peggy's gallery became the place to see works by a generation of young American artists who were tearing painting apart. She would become a key patron to the Abstract Expressionists (in particular, Jackson Pollock), at a time when few people were supporting the movement — or art in general. (It was the middle of World War II, after all.) For this report, we pay a visit to the space that, over the course of five short years in the '40s, helped transform art history. And we look at the unusual, single-minded woman who made it all happen.
