American military hero, a United States Marine Corps officer who received the Medal of Honor, the United States's highest military decoration, for his actions during the Korean War.
By 27 October 1952, he was serving as a second lieutenant with Company H of the 3rd Battalion 7th Marines. On that day, he spearheaded the capture of an enemy-held hill while wounded by enemy fire. For this action, he was awarded the Medal of Honor by President Dwight D. Eisenhower during a White House ceremony on 27 October 1953, exactly one year to the day after the action for which he was cited.
He was promoted to major in the Reserve in 1963.
After his military service, O'Brien returned to west Texas and raised a family. He was an active volunteer at the Big Spring Veterans Administration medical center. On 11 March 2005 O'Brien died from complications associated with emphysema and pneumonia in Midland, Texas.
