Notifying President Coolidge that the "Court" is now in session - Judges of Supreme Court calling at White house, Washington, D.C.

William Howard Taft (September 15, 1857 – March 8, 1930) served as the 27th President of the United States (1909–1913) and as the 10th Chief Justice of the United States (1921–1930), the only person to have held both offices. Taft was elected president in 1908 and was defeated for re-election by Woodrow Wilson in 1912 after Roosevelt split the Republican vote by running as a third-party candidate. William Taft attended Yale and was a member of Skull and Bones secret society. In 1904, Roosevelt made him Secretary of War and he became Roosevelt's hand-picked successor. After leaving office, Taft returned to Yale as a professor, continuing his political activity and working against war through the League to Enforce Peace. In 1921, President Harding appointed Taft chief justice, an office he had long sought. "Don't write so that you can be understood, write so that you can't be misunderstood."

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."

Stereographs are devices capable of building a three-dimensional​ image out of two photographs that have about two and a half inches difference between them so that it could imitate the two eyes’ real field of view. Combining these images into a single one with the help of stereoscope, a person can experience the illusion of the image’s depth. Stereoscope uses the same principle as in human binocular vision. Our eyes are separated by about two inches, so we see everything from two different angles. When the brain combined those views in a single picture, we get the spatial depth and dimension. Stereographs were extremely popular between 1850 and 1930 all around the world. Millions of stereographs were made during that time. There was a broad range of themes: landscape, travel, historical moments, nature disasters, architecture and many others.
