Henri Rousseau: A Painter's Secrets by Christopher Green Two of the greatest collections of Rousseau’s work come together in a new exhibition that offers fresh insights into the painter’s art and life   The Barnes Foundation is home to the world’s largest collection of works by the self-taught artist Henri Rousseau (1844–1910). Many of them were bought by Dr. Albert C. Barnes from the Paris art dealer Paul Guillaume, also an avid collector of Rousseau’s works. This publication offers a comprehensive study of the eighteen works at the Barnes and places them in dialogue with works from around the globe, including those from Guillaume’s collection (now housed at the Musée de l’Orangerie in Paris). This unprecedented overview of the artist’s work reunites paintings that have been apart for more than one hundred years, marking the first time that works from the Foundation’s galleries will form part of an exhibition devoted to Rousseau.
