Freedom: A History of US. This exhibition documents and illustrates critical figures and events while tracing the evolving concept of freedom from the nation's founding until 1968. Among the highlights are: a rare 1776 printing of the Declaration of Independence, a printed draft and the official copy of the US Constitution, Lincoln’s handwritten notes for speeches, and letters by leading figures such as Frederick Douglass, Susan B. Anthony, and Martin Luther King Jr. Some of the more poignant descriptions of the meaning of freedom to the common man are found in the personal letters of Civil War soldiers, which speak to the pain and pride of fighting for national ideals.
