According to the Library of Congress Theodore Roosevelt was the first U.S. President to have large portions of his career highlights captured in motion pictures. 67 of those motion picture clips can be found on the Library of Congress YouTube channel. The clips are silent and short. Watch for the text in the clips to learn a bit about President Roosevelt. I particularly like his response to an invitation to fly in a bi-plane in this film (fast forward to the 1:04 mark to find it).
