Joseph Roger O'Donnell (May 7, 1922 – August 9, 2007) was an American documentarian, photojournalist and a photographer for the United States Information Agency.

[1] The Army never approved O'Donnell's trips to Nagasaki, and it was unclear whether they would destroy photographs of dead bodies or wounded survivors.

[1] As a presidential photographer, O'Donnell captured iconic moments such as the handshake between Harry S. Truman and Gen. Douglas MacArthur on Wake Island during the Korean War and President John F. Kennedy deliberating the Bay of Pigs invasion.

[3] In 1995, controversy surrounded O'Donnell's work as the National Air and Space Museum prepared to exhibit the Enola Gay, the B-29 that bombed Hiroshima.

[4] A photograph of a saluting John F. Kennedy Jr. during the funeral for his father in 1963 was taken by Stan Stearns for United Press International, not by O'Donnell.

She mentioned that he underwent over 50 operations, including procedures on his colon and heart, and attributed his declining health to radiation exposure from his visits to Nagasaki and Hiroshima.
