Who decided which 4 faces wouldbe on mt Rushmore?

The selection of the four faces on Mount Rushmore was primarily the vision of sculptor Gutzon Borglum, who aimed to represent significant figures in American history. He chose George Washington for his role in founding the nation, Thomas Jefferson for the Declaration of Independence, Theodore Roosevelt for his contributions to the progressive era, and Abraham Lincoln for preserving the Union during the Civil War. The decision was also influenced by the support of various political figures and the cultural context of the time.
