John Calvin Coolidge Jr. (July 4, 1872 – January 5, 1933) was the 30th President of the United States (1923–29). He was elected as the 29th vice president in 1920 and succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Born in Plymouth, Vermont, on July 4, 1872, Coolidge was the son of a village storekeeper. He was graduated from Amherst College with honors and started his political career as a councilman in Northampton, Massachusetts, and became Governor of Massachusetts, as a Republican. Elected in his own right in 1924, he gained a reputation as a small-government conservative, and also as a man who said very little, although having a rather dry sense of humor. Coolidge was a popular figure and restored public confidence in the White House after the scandals of his predecessor's administration. He left office with considerable popularity amid the material prosperity which many Americans were enjoying during the 1920s era. Coolidge was both the most negative and remote of Presidents, and the most accessible. He once explained to Bernard Baruch why he often sat silently through interviews: "Well, Baruch, many times I say only 'yes' or 'no' to people. Even that is too much. It winds them up for twenty minutes more."

During the administrations of Presidents Wilson, Harding, Coolidge, and Hoover, the National Photo Company supplied photographs of current news events in Washington, D.C., as a daily service to its subscribers. It also prepared sets of pictures on popular subjects and undertook special photographic assignments for local businesses and government agencies. The bulk of the images were created between 1909 and 1932. The photographic files of the National Photo Company, including an estimated 80,000 images (photographic prints and corresponding glass negatives), were acquired by the Library from its proprietor Herbert E. French in 1947.
