how did they decide which presidents to put on mount rushmore
Having decided on the location of the sculpture, Borglum decided to make the monument of four presidents of the United States. He chose the two most famous presidents in American history, George Washington and Abraham Lincoln. He chose Thomas Jefferson because Jefferson nearly doubled the size of the United States in the 1803 Louisiana Purchase (which included the land that became South Dakota). The last president Borglum chose was Theodore Roosevelt, suggested by President Calvin Coolidge (who insisted that at least there be two Republicans and at least one Democrat represented) because of Theodore Roosevelt's introduction of the National Park Service.
