Power & Light is an exhibition of photographs by renowned documentary photographer Russell Lee telling the story of workers who helped build a nation. Russell Lee’s coal survey photographs honor a group of Americans, more diverse than we realized, who were mostly hidden from view. Power & Light: Russell Lee’s Coal Survey is made possible in part by the National Archives Foundation through the generous support of The Mars Family & Mars, Incorporated and Anonymous.

Since George Washington's oath of office in 1789, 46 presidents have taken part in the the solemn swearing-in ceremony of inauguration. The President of the United States holds the most powerful office in the world and must "take care that the laws be faithfully executed" as outlined by the Constitution way back in 1787. As head of the Executive Branch of the government, the President of the United States acts as head of state and Commander-in-Chief of the armed forces. The Vice President is also part of the Executive Branch, ready to assume the Presidency should the need arise.
