Overview

John Herschel Glenn Jr. (July 18, 1921 – December 8, 2016) was an American Marine Corps aviator, astronaut, businessman, and politician. He was the third American in space and the first to orbit the Earth, circling it three times in 1962. Following his retirement from NASA, he served from 1974 to 1999 as a U.S. senator from Ohio. In 1998, he flew into space again at the age of 77.

Before joining NASA, Glenn was a distinguished fighter pilot in World War II, the Chinese Civil War, and the Korean War. He shot down three MiG-15s and was awarded six Distinguished Flying Crosses and eighteen Air Medals. In 1957, he made the first supersonic transcontinental flight across the United States. His on-board camera took the first continuous, panoramic photograph of the United States.

Glenn was one of the Mercury Seven military test pilots selected in 1959 by NASA as the nation's first astronauts. On February 20, 1962, Glenn flew the Friendship 7 mission, becoming the first American to orbit the Earth. He was the third American, and the fifth person, to be in space. He received the NASA Distinguished Service Medal in 1962, the Congressional Space Medal of Honor in 1978, was inducted into the U.S. Astronaut Hall of Fame in 1990, and received the Presidential Medal of Freedom in 2012.

Glenn resigned from NASA in January 1964. A member of the Democratic Party, Glenn was first elected to the Senate in 1974 and served for 24 years until January 1999. In 1998, at age 77, Glenn flew on Space Shuttle Discovery's STS-95 mission, making him the oldest person to enter Earth orbit, the only person to fly in both the Mercury and the Space Shuttle programs, and the first Member of Congress to visit space since Congressman Bill Nelson in 1986. Glenn, both the oldest and the last surviving member of the Mercury Seven, died at the age of 95 on December 8, 2016.

Early life and education

John Herschel Glenn Jr. was born on July 18, 1921, in Cambridge, Ohio, the son of John Herschel Glenn Sr., who worked for a plumbing firm, and Clara Teresa Glenn (née Sproat), a teacher. His parents had married shortly before John Sr., a member of the American Expeditionary Force, left for the Western Front during World War I. The family moved to New Concord, Ohio, soon after his birth, and his father started his own business, the Glenn Plumbing Company. Glenn Jr. was only a toddler when he met Anna Margaret (Annie) Castor, whom he would later marry. The two would not be able to recall a time when they did not know each other. He first flew in an airplane with his father when he was eight years old. He became fascinated by flight and built model airplanes from balsa wood kits. Along with his adopted sister Jean, he attended New Concord Elementary School. He washed cars and sold rhubarb to earn money to buy a bicycle, after which he took a job delivering The Columbus Dispatch newspaper. He was a member of the Ohio Rangers, an organization similar to the Cub Scouts. His boyhood home in New Concord has been restored as a historic house museum and education center.

Glenn attended New Concord High School, where he played on the varsity football team as a center and linebacker. He also made the varsity basketball and tennis teams and was involved with Hi-Y, a junior branch of the YMCA. After graduating in 1939, Glenn entered Muskingum College (now Muskingum University), where he studied chemistry, joined the Stag Club fraternity, and played on the football team. Annie majored in music with minors in secretarial studies and physical education and competed on the swimming and volleyball teams, graduating in 1942. Glenn earned a private pilot license and a physics course credit for free through the Civilian Pilot Training Program in 1941. He did not complete his senior year in residence or take a proficiency exam, both required by the school for its Bachelor of Science degree.

Military career

When the United States entered World War II, Glenn quit college to enlist in the U.S. Army Air Corps. He was not called to duty by the army and enlisted as a U.S. Navy aviation cadet in March 1942. Glenn attended the University of Iowa in Iowa City for pre-flight training and made his first solo flight in a military aircraft at Naval Air Station Olathe in Kansas, where he went for primary training. During advanced training at Naval Air Station Corpus Christi in Texas, he accepted an offer to transfer to the U.S. Marine Corps. Having completed his flight training in March 1943, Glenn was commissioned as a second lieutenant. Glenn married Annie in a Presbyterian ceremony at College Drive Church in New Concord on April 6, 1943. After advanced training at Camp Kearny, California, he was assigned to Marine Squadron VMJ-353, which flew R4D transport planes from there.

The fighter squadron VMO-155 was also at Camp Kearny flying the Grumman F4F Wildcat. Glenn approached the squadron's commander, Major J. P. Haines, who suggested that he could put in for a transfer. This was approved, and Glenn was posted to VMO-155 on July 2, 1943, two days before the squadron moved to Marine Corps Air Station El Centro in California. The Wildcat was obsolete by this time, and VMO-155 re-equipped with the F4U Corsair in September 1943. He was promoted to first lieutenant in October 1943, and shipped out to Hawaii in January 1944. VMO-155 became part of the garrison on Midway Atoll on February 21, then moved to the Marshall Islands in June 1944 and flew 57 combat missions in the area. He received two Distinguished Flying Crosses and ten Air Medals.

At the end of his one-year tour of duty in February 1945, Glenn was assigned to Marine Corps Air Station Cherry Point in North Carolina, then to Naval Air Station Patuxent River in Maryland. He was promoted to captain in July 1945 and ordered back to Cherry Point. There, he joined VMF-913, another Corsair squadron, and learned that he had qualified for a regular commission. In March 1946, he was assigned to Marine Corps Air Station El Toro in southern California. He volunteered for service with the occupation in North China, believing it would be a short tour. He joined VMF-218 (another Corsair squadron), which was based at Nanyuan Field near Beijing, in December 1946, and flew patrol missions until VMF-218 was transferred to Guam in March 1947.

In December 1948, Glenn was re-posted to NAS Corpus Christi as a student at the Naval School of All-Weather Flight before becoming a flight instructor. In July 1951, he traveled to the Amphibious Warfare School at Marine Corps Base Quantico in northern Virginia for a six-month course. He then joined the staff of the commandant of the Marine Corps Schools. He maintained his proficiency (and flight pay) by flying on weekends, although he was only allowed four hours of flying time per month. He was promoted to major in July 1952. Glenn received the World War II Victory Medal, American Campaign Medal, Asiatic-Pacific Campaign Medal (with one star), Navy Occupation Service Medal (with Asia clasp), and the China Service Medal for his efforts.

Glenn moved his family back to New Concord during a short period of leave, and after two and a half months of jet training at Cherry Point, was ordered to South Korea in October 1952, late in the Korean War. Before he set out for Korea in February 1953, he applied to fly the F-86 Sabre jet fighter-interceptor through an inter-service exchange position with the U.S. Air Force (USAF). In preparation, he arranged with Colonel Leon W. Gray to check out the F-86 at Otis Air Force Base in Massachusetts. Glenn reported to K-3, an airbase in South Korea, on February 3, 1953, and was assigned to be the operations officer for VMF-311, one of two Marine fighter squadrons there while he waited for the exchange assignment to go through. VMF-311 was equipped with the F9F Panther jet fighter-bomber. Glenn's first mission was a reconnaissance flight on February 26. He flew 63 combat missions in Korea with VMF-311 and was nicknamed "Magnet Ass" because of the number of flak hits he took on low-level close air support missions; twice, he returned to base with over 250 holes in his plane. He flew for a time with Marine reservist Ted Williams (then in the midst of a Hall of Fame baseball career with the Boston Red Sox) as his wingman. Williams later said about Glenn, "Absolutely fearless. The best I ever saw. It was an honor to fly with him." Glenn also flew with future major general Ralph H. Spanjer.

NASA career

On October 4, 1957, the Soviet Union launched Sputnik 1, the first artificial satellite. This damaged American confidence in its technological superiority, creating a wave of anxiety known as the Sputnik crisis. In response, President Dwight D. Eisenhower launched the Space Race. The National Aeronautics and Space Administration (NASA) was established on October 1, 1958, as a civilian agency to develop space technology. One of its first initiatives was announced on December 17, 1958. This was Project Mercury, which aimed to launch a man into Earth orbit, return him safely to the Earth, and evaluate his capabilities in space.

His Bureau of Aeronautics job gave Glenn access to new spaceflight news, such as the X-15 rocket plane. While on duty at Patuxent and in Washington, Glenn read everything he could find about space. His office was asked to send a test pilot to Langley Air Force Base in Virginia to make runs on a spaceflight simulator, as part of research by the newly formed NASA into re-entry vehicle shapes. The pilot would also be sent to the Naval Air Development Center in Johnsville, Pennsylvania, and would be subjected to high G-forces in a centrifuge for comparison with data collected in the simulator. His request for the position was granted, and he spent several days at Langley and a week in Johnsville for the testing. As one of the very few pilots to have done such testing, Glenn had become an expert on the subject. NASA asked military-service members to participate in planning the mockup of a spacecraft. Having participated in the research at Langley and Johnsville, he was sent to the McDonnell plant in St. Louis as a service adviser to NASA's spacecraft mockup board. Envisioning himself in the vehicle, Glenn stated that the passenger would have to be able to control the spacecraft. McDonnell engineers told him of the importance of lightening the vehicle as much as possible, so Glenn began exercising to lose the 30 pounds (14 kg) by which he estimated he was overweight.

Eisenhower directed NASA to recruit its first astronauts from military test pilots. Of 508 graduates of test pilot schools, 110 matched the minimum standards. Marine Corps pilots were mistakenly omitted at first; two were quickly found, including Glenn. The candidates had to be younger than 40, possess a bachelor's degree or equivalent, and be 5 feet 11 inches (1.80 m) or less. Only the height requirement was strictly enforced, owing to the size of the Project Mercury spacecraft. This was fortunate for Glenn, who barely met the requirements, as he was near the age cutoff and lacked a science-based degree, but had taken more classes since leaving college than needed for graduation. Glenn was otherwise so outstanding a candidate that Colonel Jake Dill, his commanding officer at test pilot school, visited NASA headquarters to insist that Glenn would be the perfect astronaut.

For an interview with Charles Donlan, associate director of Project Mercury, Glenn brought the results from the centrifuge to show that he had done well on a test that perhaps no other candidate had taken. Donlan also noticed that Glenn stayed late at night to study schematics of the Mercury spacecraft. He was among the 32 of the first 69 candidates that passed the first step of the evaluation and were interested in continuing, sufficient for the astronaut corps NASA wanted. On February 27 a grueling series of physical and psychological tests began at the Lovelace Clinic and the Wright Aerospace Medical Laboratory.

Because of his Bureau of Aeronautics job, Glenn was already participating in Project Mercury; while other candidates were at Wright, on March 17 he and most of those who would choose the astronauts visited the McDonnell plant building the spacecraft to inspect its progress and make changes. While Glenn had not scored the highest on all the tests, a member of the selection committee recalled how he had impressed everyone with his "strength of personality and his dedication". On April 6 Donlan called Glenn to offer him a position at Project Mercury, one of seven candidates chosen as astronauts. Glenn was pleased while Annie was supportive but wary of the danger; during his three years at Patuxent, 12 test pilots had died.

Political campaigning

At 42, Glenn was the oldest member of the astronaut corps and would likely be close to 50 by the time the lunar landings took place. During Glenn's training, NASA psychologists determined that he was the astronaut best suited for public life. Attorney General Robert F. Kennedy suggested to Glenn and his wife in December 1962 that he run for the 1964 United States Senate election in Ohio, challenging aging incumbent Stephen M. Young (1889–1984) in the Democratic primary election. As it seemed unlikely that he would be selected for Project Apollo missions, he resigned from NASA on January 16, 1964, and announced his Democratic Party candidacy for the U.S. Senate from his home state of Ohio the following day, becoming the first astronaut-politician. Glenn was still a Marine and had plenty of unused leave time, so he elected to use it while he waited for his retirement papers to go through.

To avoid partisanship, NASA quickly closed Glenn's agency office. The New York Times reported that while many Ohioans were skeptical of Glenn's qualifications for the Senate, he could defeat Young in the Democratic primary; whether he could defeat Representative Robert Taft Jr., the likely Republican candidate, in the general election was much less clear. In late February he was hospitalized for a concussion sustained in a fall against a bathtub while attempting to fix a mirror in a hotel room; an inner-ear injury from the accident left him unable to campaign. Both his wife and Scott Carpenter campaigned on his behalf during February and March, but doctors gave Glenn a recovery time of one year. Glenn did not want to win solely because of his astronaut fame, so he dropped out of the race on March 30.

Glenn was still on leave from the Marine Corps, and he withdrew his papers to retire so he could keep a salary and health benefits. Glenn was on the list of potential candidates to be promoted to full colonel, but he notified the commandant of the Marine Corps of his intention to retire so another Marine could receive the promotion. President Johnson later decided to promote Glenn to full colonel status without taking someone else's slot. He retired as a colonel on January 1, 1965. Glenn was approached by RC Cola to join their public relations department, but Glenn declined it because he wanted to be involved with a business and not just the face of it. The company revised their offer and offered Glenn a vice president of corporate development position, as well as a place on the board of directors. The company later expanded Glenn's role, promoting him to president of Royal Crown International. A Senate seat was open in 1968, and Glenn was asked about his current political aspirations. He said he had no current plan, and "Let's talk about it one of these days." Glenn also said that a 1970 Senate run was a possibility.

In 1973, he and a friend bought a Holiday Inn near Disney World. The success of Disney World expanded to their business, and the pair built three more hotels. One of Glenn's business partners was Henri Landwirth, a Holocaust survivor who became his best friend. He remembered learning about Landwirth's background: "Henri doesn't talk about it much. It was years before he spoke about it with me and then only because of an accident. We were down in Florida during the space program. Everyone was wearing short-sleeved Ban-Lon shirts—everyone but Henri. Then one day I saw Henri at the pool and noticed the number on his arm. I told Henri that if it were me I'd wear that number like a medal with a spotlight on it."

Glenn remained close to the Kennedy family, and campaigned for Robert F. Kennedy during his 1968 presidential campaign. In 1968, Glenn was in Kennedy's hotel suite when Kennedy heard he had won California. Glenn was supposed to go with him to celebrate but decided not to as there would be many people there. Kennedy went downstairs to make his victory speech and was assassinated. Glenn and Annie went with Kennedy to the hospital, and the next morning took Kennedy's children home to Virginia. Glenn was later a pallbearer at the funeral in New York.

U.S. Senate (1974–1999)

Glenn requested to be assigned to two committees during his first year as senator: the Government Operations Committee (later known as the Committee on Governmental Affairs), and the Foreign Relations Committee. He was immediately assigned to the Government Operations Committee and waited for a seat on the Foreign Relations Committee. In 1977, Glenn wanted to chair the Energy, Nuclear Proliferation, and Federal Services Subcommittee of the Governmental Affairs Committee. Abraham Ribicoff, chair of the Governmental Affairs Committee, said he could chair the subcommittee if he also chaired the less popular Federal Services Subcommittee, which was in charge of the U.S. Postal Service. Previous chairs of the Federal Services Subcommittee had lost elections in part because of negative campaigns associated with the poorly regarded mail service to the chairmen, but Glenn accepted the offer and became the chair of both subcommittees. One of his goals as a new senator was developing environmental policies. Glenn introduced bills on energy policy to try to counter the energy crisis in the 70s. Glenn also introduced legislation promoting nuclear non-proliferation and was the chief author of the Nuclear Non-Proliferation Act of 1978, the first of six major pieces of legislation that he produced on the subject.

Glenn chaired the Committee on Governmental Affairs from 1987 to 1995. It was in this role that he discovered safety and environmental problems with the nation's nuclear weapons facilities. Glenn was made aware of the problem at the Fernald Feed Materials Production Center near Cincinnati and soon found that it affected sites across the nation. Glenn requested investigations from the General Accounting Office of Congress and held several hearings on the issue. He also released a report on the potential costs of hazardous waste cleanup at former nuclear weapons manufacturing facilities, known as the Glenn Report. He spent the remainder of his Senate career acquiring funding to clean up the nuclear waste left at the facilities.

Glenn also focused on reducing government waste. He created legislation to mandate CFOs for large governmental agencies. Glenn wrote a bill to add the office of the inspector general to federal agencies, to help find waste and fraud. He also created legislation intended to prevent the federal government from imposing regulations on local governments without funding. Glenn founded the Great Lakes Task Force, which helped protect the environment of the Great Lakes.

In 1995 Glenn became the ranking minority member of the Committee on Governmental Affairs. Glenn disputed the focus on illegal Chinese donations to the Democrats and asserted that Republicans also had egregious fundraising issues. The committee chair, Fred Thompson of Tennessee, disagreed and continued the investigation. Thompson and Glenn continued to work together poorly for the duration of the investigation. Thompson would give Glenn only information he was legally required to. Glenn would not authorize a larger budget and tried to expand the scope of the investigation to include members of the GOP. The investigation concluded with a Republican-written report, which Thompson described as, "... a lot of things strung together that paint a real ugly picture." The Democrats, led by Glenn, said the report "... does not support the conclusion that the China plan was aimed at, or affected, the 1996 presidential election."

Glenn was the vice chairman of the Permanent Subcommittee on Investigations, a subcommittee of the Committee on Governmental Affairs. When the Republican Party regained control of the Senate in 1996, Glenn became the ranking minority member on the Permanent Subcommittee on Investigations until he was succeeded by Carl Levin. During this time, the committee investigated issues such as fraud on the Internet, mortgage fraud, and day trading of securities.

Return to space

After the Space Shuttle Challenger disaster in 1986, Glenn criticized putting a "lay person in space for the purpose of gaining public support ... while the shuttle is still in its embryonic stage". He supported flying research scientists. In 1995, Glenn read Space Physiology and Medicine, a book written by NASA doctors. He realized that many changes that occur to physical attributes during space flight, such as loss of bone and muscle mass and blood plasma, are the same as changes that result from aging. Glenn thought NASA should send an older person on a shuttle mission, and that it should be him. Starting in 1995, he began lobbying NASA director Dan Goldin for the mission. Goldin said he would consider it if there was a scientific reason, and if Glenn could pass the same physical examination the younger astronauts took. Glenn performed research on the subject and passed the physical examination. On January 16, 1998, NASA Administrator Dan Goldin announced that Glenn would be part of the STS-95 crew; this made him, at age 77, the oldest person to fly in space at that time.

NASA and the National Institute of Aging (NIA) planned to use Glenn as a test subject for research, with biometrics taken before, during, and after his flight. Some experiments (in circadian rhythms, for example) compared him with the younger crew members. In addition to these tests, he was in charge of the flight's photography and videography. Glenn returned to space on the Space Shuttle on October 29, 1998, as a payload specialist on Space Shuttle Discovery. Shortly before the flight, researchers disqualified Glenn from one of the flight's two major human experiments (on the effect of melatonin) for undisclosed medical reasons; he participated in experiments on sleep monitoring and protein use. On November 6, President Bill Clinton sent a congratulatory email to Glenn aboard Discovery. This is often cited as the first email sent by a sitting U.S. president, but records exist of emails being sent by President Clinton several years earlier.

His participation in the nine-day mission was criticized by some members of the space community as a favor granted by Clinton; John Pike, director of the Federation of American Scientists' space-policy project, said: "If he was a normal person, he would acknowledge he's a great American hero and that he should get to fly on the shuttle for free ... He's too modest for that, and so he's got to have this medical research reason. It's got nothing to do with medicine".

In a 2012 interview, Glenn said he regretted that NASA did not continue its research on aging by sending additional elderly people into space. After STS-95 returned safely, its crew received a ticker-tape parade. On October 15, 1998, NASA Road 1 (the main route to the Johnson Space Center) was temporarily renamed John Glenn Parkway for several months. Glenn was awarded the NASA Space Flight Medal in 1998 for flying on STS-95. In 2001, Glenn opposed sending Dennis Tito, the world's first space tourist, to the International Space Station because Tito's trip had no scientific purpose.

Personal life

Glenn and Annie had two children—John David and Carolyn Ann—and two grandchildren, and remained married for 73 years until his death.

A Freemason, Glenn was a member of Concord Lodge No. 688 in New Concord, Ohio. He received all his degrees in full in a Freemason at sight ceremony from the Grand Master of Ohio in 1978, 14 years after petitioning his lodge. In 1999, Glenn became a 33rd-degree Scottish Rite Mason in the Valley of Cincinnati (NMJ). As an adult, he was honored as part of the DeMolay Legion of Honor by DeMolay International, a Masonic youth organization for boys.
