Treaty of Traverse des Sioux

This painting by Francis David Millet, after a sketch by Frank Blackwell Mayer, completed more that 50 years after the event it depicts, is believed to contain portraits of many of the key players in the treaty negotiations, including commissioner Luke Lea (center, with outstretched hand); Alexander Ramsey (behind Lea); Henry Sibley (behind Ramsey); and missionaries Thomas Williamson (back row, second from left) and Stephen Riggs (back Row, fourth from left).
