According to noted expert Harold Holzer, United States President Abraham Lincoln transformed the city of Washington, DC-not only into the command center of a great war and executive authority, but also a mecca for artists. In this podcast recorded on February 14, 2010, at the National Gallery of Art, Holzer sheds light on this transformation and on the role of these artists, who recorded the great events of the day and whose works documented the evolving image of the 16th president.
