John Herschel Glenn Jr. (July 18, 1921 – December 8, 2016) was an American aviator, engineer, astronaut, and United States Senator from Ohio. In 1962 he became the first American to orbit the Earth, circling three times. Before joining NASA, he was a distinguished fighter pilot in both World War II and Korea, with six Distinguished Flying Crosses and eighteen clusters to the Air Medal.
Glenn was one of the “Mercury Seven” group of military test pilots selected in 1959 by NASA to become America’s first astronauts. On February 20, 1962, he flew the Friendship 7 mission and became the first American to orbit the Earth and the fifth person in space. Glenn received the Congressional Space Medal of Honor in 1978, was inducted into the U.S. Astronaut Hall of Fame in 1990, and was the last surviving member of the Mercury Seven.
After he resigned from NASA in 1964, Glenn planned to run for a U.S. Senate seat from Ohio. A member of the Democratic Party, he first won election to the Senate in 1974 where he served through January 3, 1999.
He retired from the Marine Corps in 1965, after twenty-three years in the military, with over fifteen medals and awards, including the NASA Distinguished Service Medal and the Congressional Space Medal of Honor. In 1998, while still a sitting senator, he became the oldest person to fly in space, and the only one to fly in both the Mercury and Space Shuttle programs as crew member of the Discovery space shuttle. He was also awarded the Presidential Medal of Freedom in 2012.
John Glenn was born on July 18, 1921, in Cambridge, Ohio, the son of John Herschel Glenn, Sr. (1895–1966) and Clara Teresa (née Sproat) Glenn (1897–1971). He was raised in nearby New Concord.
After graduating from New Concord High School in 1939, he studied Engineering at Muskingum College. He earned a private pilot license for credit in a physics course in 1941. Glenn did not complete his senior year in residence or take a proficiency exam, both requirements of the school for the Bachelor of Science degree. However, the school granted Glenn his degree in 1962, after his Mercury space flight.
When the Japanese attack on Pearl Harbor brought the United States into World War II, Glenn quit college to enlist in the U.S. Army Air Corps. However, he was never called to duty, and in March 1942 enlisted as a United States Navy aviation cadet. He went to the University of Iowa for preflight training, then continued on to NAS Olathe, Kansas, for primary training. He made his first solo flight in a military aircraft there. During his advanced training at the NAS Corpus Christi, he was offered the chance to transfer to the U.S. Marine Corps and took it.
Upon completing his training in 1943, Glenn was assigned to Marine Squadron VMJ-353, flying R4D transport planes. He transferred to VMF-155 as an F4U Corsair fighter pilot, and flew 59 combat missions in the South Pacific. He saw combat over the Marshall Islands, where he attacked anti-aircraft batteries on Maloelap Atoll. In 1945, he was assigned to NAS Patuxent River, Maryland, and was promoted to captain shortly before the war’s end.
Glenn flew patrol missions in North China with the VMF-218 Marine Fighter Squadron, until it was transferred to Guam. In 1948 he became a flight instructor at NAS Corpus Christi, Texas, followed by attending the Amphibious Warfare School.
During the Korean War, Glenn was assigned to VMF-311, flying the new F9F Panther jet interceptor. He flew his Panther in 63 combat missions, gaining the nickname “magnet ass” from his alleged ability to attract enemy flak. On two occasions, he returned to his base with over 250 holes in his aircraft. For a time, he flew with Marine reservist Ted Williams, a future Hall of Fame baseball player for the Boston Red Sox, as his wingman. He also flew with future Major General Ralph H. Spanjer.
Glenn flew a second Korean combat tour in an interservice exchange program with the United States Air Force, 51st Fighter Wing. He logged 27 missions in the faster F-86F Sabre and shot down three MiG-15s near the Yalu River in the final days before the ceasefire.
For his service in 149 combat missions in two wars, he received numerous honors, including the Distinguished Flying Cross (six occasions) and the Air Medal with eighteen award stars.

Glenn returned to NAS Patuxent River, appointed to the U.S. Naval Test Pilot School (class 12), graduating in 1954. He served as an armament officer, flying planes to high altitude and testing their cannons and machine guns. He was assigned to the Fighter Design Branch of the Navy Bureau of Aeronautics (now Bureau of Naval Weapons) as a test pilot on Navy and Marine Corps jet fighters in Washington, D.C., from November 1956 to April 1959, during which time he also attended the University of Maryland.
Glenn had nearly 9,000 hours of flying time, with approximately 3,000 hours in jet aircraft.
On July 16, 1957, Glenn completed the first supersonic transcontinental flight in a Vought F8U-3P Crusader. The flight from NAS Los Alamitos, California, to Floyd Bennett Field, New York, took 3 hours, 23 minutes and 8.3 seconds. As he passed over his hometown, a child in the neighborhood reportedly ran to the Glenn house shouting “Johnny dropped a bomb! Johnny dropped a bomb! Johnny dropped a bomb!” as the sonic boom shook the town. Project Bullet, the name of the mission, included both the first transcontinental flight to average supersonic speed (despite three in-flight refuelings during which speeds dropped below 300 mph), and the first continuous transcontinental panoramic photograph of the United States. For this mission Glenn received his fifth Distinguished Flying Cross.
Glenn wasn’t finished. He went on to flying much higher.
