The President of the United States of America takes pleasure in presenting the Navy and Marine Corps Medal to Chief Hospital Corpsman William H. Berryman, United States Navy, for heroic conduct on 15 December 1961 while serving with Explosive Ordnance Disposal Unit One, Pearl Harbor, Oahu, Hawaii. Engaged in diving operations at a depth of 75 feet in waters off Pearl Harbor Entrance when a fellow diver experienced difficulty and began to go into convulsions, Chief Berryman, along with another diver, quickly moved to assist the victim to the surface. Despite the great personal danger from the physiological effects of emergency ascent from the ocean depths, Chief Berryman persisted in his rescue efforts at the same time taking the necessary actions to prevent further mishap to the disabled diver. After reaching the surface and placing the helpless man in the diving boat, Chief Berryman administered first aid and resuscitation until medical facilities could be reached at the Submarine Base, Pearl Harbor.
