The Congressional Gold Medal is the oldest and joint-highest civilian award in the United States, alongside the Presidential Medal of Freedom. It is bestowed by vote of the United States Congress, signed into law by the president. The Gold Medal expresses the highest national appreciation for distinguished achievements and contributions by individuals or institutions.
The congressional practice of issuing gold medals to occasionally honor recipients began with members of the military during the American Revolution. The practice soon extended to individuals in all walks of life and in the late 20th century also to groups. The congressional medal honors those, individually or as a group, "who have performed an achievement that has an impact on American history and culture that is likely to be recognized as a major achievement in the recipient's field long after the achievement."
