A traveling exhibit celebrating the American Civil Liberties Union’s 90th anniversary will be unveiled in Indianapolis Friday.

The exhibit highlights the work of the organization over the last nine decades and illustrates the organization’s major contributions to defending the freedoms promised in the Constitution. It provides a historical overview of the ACLU’s achievements since its founding in 1920. It includes stories on John Scopes, the teacher accused of violating a Tennessee state law against the teaching of evolution in the 1920s; Ozzie Powell, one of the "Scottsboro Boys" sentenced to death in Alabama in the 1930s for allegedly raping a white woman, a crime he did not commit; and Mildred and Richard Loving, an interracial couple charged in the 1960s with violating Virginia's "Racial Integrity Act.”

Legislation that the ACLU had a major role in passing will also be in the exhibit, including the Family and Medical Leave Act of 1993, as well as other civil liberty milestones, such as upholding free speech and privacy on the Internet.

The exhibit will be on display at the Indianapolis-Marion County Public Library through Sept. 16. The exhibit will also visit many other states including Iowa, Kentucky, and Tennessee. It’s also available online as an interactive exhibit.
