Borglum demonstrated a passion for art from an early age. After completing his formal art training, he gained recognition as a sculptor and eventually emerged as one of the leading sculptors in the United States during the early 20th century. His sculptures often depicted historical events, patriotic themes, and human forms.
Borglum's most famous and enduring work is the Mount Rushmore National Memorial. He directed the sculpting of the gigantic faces of four U.S. presidents (George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln) onto the granite face of Mount Rushmore, which took place from 1927 until his death in 1941. The project, initiated by Borglum and completed by his son, Lincoln Borglum, remains an awe-inspiring testament to his artistic vision and technical skill as a sculptor.
While Borglum did create some paintings, particularly during his younger years, his contributions as a painter are not considered as significant or as enduring as his sculptures. He primarily made his mark and achieved his fame as a gifted and accomplished sculptor.
