John H. Glenn was born July 18, 1921 in Cambridge, Ohio. He attended schools in New Concord, Ohio, and Muskingum College in New Concord, receiving a Bachelor of Science degree in Engineering. Muskingum College also awarded him an honorary Doctor of Science degree in engineering. He has received honorary doctoral degrees from nine colleges or universities.
Glenn has received numerous awards including the Distinguished Flying Cross on six occasions, the Air Medal with 18 Clusters for his service during World War II and Korea, the Navy Unit Commendation for service in Korea, the Asiatic-Pacific Campaign Medal, the American Campaign Medal, the World War II Victory Medal, the China Service Medal, the National Defense Service Medal, the Korean Service Medal, the United Nations Service Medal, the Korean Presidential Unit Citation, the Navy's Astronaut Wings, the Marine Corps' Astronaut Medal, the NASA Distinguished Service Medal, and the Congressional Space Medal of Honor.
Glenn entered the Naval Aviation Cadet Program in March 1942 and was graduated and commissioned in the Marine Corps in 1943. After advanced training, he joined Marine Fighter Squadron 155 and spent a year flying F-4U fighters in the Marshall Islands.
During World War II, he flew 59 combat missions. After the war, he was a member of Marine Fighter Squadron 218 on the North China patrol and served on Guam. From June 1948 to December 1950, Glenn taught advanced flight training in Texas and then attended Amphibious Warfare Training at Quantico, Virginia. In Korea he flew 90 missions with the Marines and the Air Force. In the last nine days of fighting in Korea, Glenn downed three MIGs along the Yalu River.
In July 1957, he set a transcontinental speed record from Los Angeles to New York, spanning the country in 3 hours and 23 minutes. This was the first transcontinental flight to average supersonic speed. Glenn has nearly 9,000 hours of flying time, with approximately 3,000 hours in jet aircraft.
Glenn was assigned to the NASA Space Task Group in April 1959, after his selection as a Project Mercury astronaut. On February 20, 1962, Glenn piloted the Mercury-Atlas 6 Friendship 7 spacecraft on the first piloted orbital mission of the United States. He completed three-orbits around the Earth, reaching a maximum altitude of approximately 162 statute miles and an orbital velocity of approximately 17,500 miles per hour.
Glenn resigned from NASA's Manned Spacecraft Center (later renamed Johnson Space Center) in January 1964. He was promoted to the rank of Colonel in October 1964 and retired from the Marine Corps on January 1, 1965. Glenn worked in business from 1965 until his election to the U.S. Senate in November 1974, where he served until his retirement in January 1999.
From October 29 to November 7, 1998, Glenn flew as a payload specialist on STS-95 Discovery. The mission traveled 3.6 million miles in 213 hours and 44 minutes, circling the Earth 134 times.
In total, Glenn has logged more than 218 hours in space.
