John Henry “Jack” “Doc” Bradley (July 10, 1923 – January 11, 1994) was a United States Navy Hospital corpsman who was awarded the Navy Cross for extraordinary heroism in combat on Iwo Jima during World War II. Bradley also partook twice in raising the Flag on Iwo Jima, on February 23, 1945. He helped secure the first American flag attached to a pipe, in the ground, after it was raised and planted on top of Mount Suribachi. When a larger flag was ordered to replace the first flag the same day, he helped five Marines raise and plant the second flag attached to a longer and heavier pipe. Bradley was the last surviving member of the second flag-raising event.
