In the process of reinventing watercolor, American painter John Marin transformed American painting. Martha Tedeschi, curator of prints and drawings, and Kristi Dahm, assistant conservator of prints and drawings, explore the life, innovations, and legacy of this profoundly influential artist. The exhibition John Marin's Watercolors: A Medium for Modernism ran through January 23–April 17, 2011, at the Art Institute of Chicago.
