Known for his distinctive drawl and everyman screen persona, Stewart's film career spanned 80 films from 1935 to 1991. With the strong morality, which he portrayed both on and off the screen, he epitomized the "American ideal" in the mid-twentieth century.

He received numerous honors including the AFI Life Achievement Award in 1980, the Kennedy Center Honor in 1983, as well as the Academy Honorary Award and Presidential Medal of Freedom, both in 1985.
Born and raised in Indiana, Pennsylvania, Stewart started acting while at Princeton University. After graduating, he began a career as a stage actor making his Broadway debut in the play Carry Nation (1932). He landed his first supporting role in The Murder Man (1935) and had his breakthrough in Frank Capra's ensemble comedy You Can't Take It with You (1938).

His other Oscar-nominated roles were in Mr. Smith Goes to Washington (1939), It's a Wonderful Life (1946), Harvey (1950) and Anatomy of a Murder (1959).
Stewart played darker, more morally ambiguous characters in movies directed by Anthony Mann, including Winchester '73 (1950), The Glenn Miller Story (1954), and The Naked Spur (1953), and by Alfred Hitchcock in Rope (1948), Rear Window (1954), The Man Who Knew Too Much (1956), and Vertigo (1958). Stewart also starred in The Greatest Show on Earth (1952), The Spirit of St. Louis (1957), The Flight of the Phoenix (1965) as well as the Western films How the West Was Won (1962), The Man Who Shot Liberty Valance (1962), and Cheyenne Autumn (1964).

Captain George Francis Kosco (1 April 1908 – 11 June 1985) was a United States Navy aerologist and polar explorer.
Kosco was born in Ramsaytown, Pennsylvania, on 1 April 1908. He was a Slovak American: his father had come from Oľšov, and his mother from Plavnica. His family name had been "Kvasnak", but this was changed to "Kosco" when his parents emigrated to the United States. Kosco graduated from the United States Naval Academy in 1930, and earned a master's degree in weather aerology from the Massachusetts Institute of Technology in 1940. His dissertation, co-authored with John O. F. Dorsett, was called Winter weather types of the eastern North Pacific and adjacent coastal and island areas.Kosco spent much of the 1930s hurricane hunting in the Caribbean. In 1939 he married Bernadette Howley (1912–2013); the couple had three children. Bob Drury and Tom Clavin describe him as a "handsome, athletic six-footer", while Buckner F. Melton Jr. calls him "a slightly stout moon-faced officer".Kosco was assigned to Admiral William Halsey Jr.'s Third Fleet in early October 1944. In December, the fleet was struck by Typhoon Cobra, which destroyed three ships. Kosco, aboard the USS New Jersey, reported a "tropical disturbance" 600 miles (970 km) to the east, and moving away from the fleet, when in fact it was a full-blown typhoon 200 miles (320 km) away and coming towards the fleet. Kosco later admitted to a board of inquiry that he had underestimated Cobra's strength, "basing his prediction on historical data about regional storms rather than relying upon current local observations." He was "mildly reprimanded". In 1967, Kosco published an account of the incident coauthored with Hans Christian Adamson: Halsey's Typhoons: A Firsthand Account of How Two Typhoons, More Powerful than the Japanese, Dealt Death and Destruction to Admiral Halsey's Third Fleet.Kosco was present at the signing ceremony of the Japanese surrender on the USS Missouri at Tokyo Bay on 2 September 1945. He took what is believed to be the only color film footage of the ceremony. This was only released publicly in 2010.In 1946 Kosco participated in Operation Nanook in the Arctic. He was then chief aerologist and chief scientist in Operation Highjump in the Antarctic with Rear Admiral Richard E. Byrd Jr. in 1946–47. He also led several other polar expeditions, collecting specimens for the Smithsonian Institution. Kosco Glacier in Antarctica was named in his honor in 1962.Kosco retired from the Navy in 1960. He died on 11 June 1985 at Bethesda Naval Hospital, and was buried at Arlington National Cemetery.
