Over the past two centuries, the role of the First Lady has changed immensely and in the past several decades the women to occupy this position have embraced causes such as literacy and healthy eating. This online exhibit from the National Museum of American History looks at the "role played by the country's first ladies as well as the beautiful objects that belonged to them." The site is divided into six sections, including "The First Ladies Collection" and "A First Lady's Contribution". The "First Ladies Collection" contains photos and descriptions of items like Martha Washington's silk taffeta gown and Dolley Madison's elaborate hand-embroidered robe. Moving on, "A First Lady's Contribution" contains images of the First Ladies on the campaign trail and other settings. One particularly interesting image here is that of Florence Harding pinning a flower on Al Jolson's lapel during a campaign stop. Finally, visitors can also view a timeline of all the First Ladies.
