John Henry Bradley was a United States Navy Hospital corpsman who was awarded the Navy Cross for extraordinary heroism in combat on February 21, 1945 while assigned to a U.S. Marine Corps rifle company during the Battle of Iwo Jima in World War II. Bradley was one of the members of the combat patrol that climbed, captured, and helped raise the original U.S. flags on top of Mount Suribachi on the morning of February 23, 1945. Until June 2016, Bradley was incorrectly identified as being one of the six men raising a second, larger flag about 90 minutes later, though he was still on the mountaintop. He witnessed – but was not part of – the specific moment of raising the larger flag that was captured in the Pulitzer Prize-winning photo "Raising the Flag on Iwo Jima" taken by Associated Press photographer Joe Rosenthal. His story was related in the book, "Flags of Our Fathers", by his son James.
James's brother Thomas John Bradley married Laurel Ann Johnson, whose great-grandmother was Anna Lydia (Filpus) Silfven.
