The President of the United States of America takes pleasure in presenting the Navy and Marine Corps Medal to Boatswain’s Mate Second Class Robert C. Mizen, United States Navy, for heroic actions while serving aboard U.S.S. KEPPLER (DD-765) at the Boston Naval Shipyard, Boston, Massachusetts, on the morning of 3 February 1965. Learning that a shipmate was trapped in a compartment filled with carbon dioxide, Boatswain’s Mate Second Class Mizen, fully aware of the extreme danger involved, unhesitatingly entered the compartment by the only means of access, a narrow trunk, and rescued the man.
