James Maitland "Jimmy" Stewart (May 20, 1908 – July 2, 1997) was an American film and stage actor, known for his distinctive voice and persona. Over the course of his career, he starred in many films widely considered classics and was nominated for five Academy Awards, winning one in competition and receiving one Lifetime Achievement award. He was a major MGM contract star. He also had a noted military career and was a World War II and Vietnam War veteran, who rose to the rank of Brigadier General in the United States Air Force Reserve.

James Maitland Stewart was born on May 20, 1908, in Indiana, Pennsylvania, the son of Elizabeth Ruth (née Jackson) and Alexander Maitland Stewart, who owned a hardware store. Stewart's parents were of Scottish descent and Presbyterians. His maternal ancestors served in the American Revolution, the War of 1812 and the American Civil War. The eldest of three children (he had two younger sisters, Virginia and Mary), he was expected to continue his father's business, which had been in the family for three generations. His mother was an excellent pianist but his father discouraged Stewart's request for lessons. But when his father accepted a gift of an accordion from a guest, young Stewart quickly learned to play the instrument, which became a fixture off-stage during his acting career. As the family grew, music continued to be an important part of family life.

Sherlock Holmes ( /ˈʃɜrlɒk ˈhoʊmz/) is a fictional detective created by Scottish author and physician Sir Arthur Conan Doyle. The fantastic London-based "consulting detective", Holmes is famous for his astute logical reasoning, his ability to adopt almost any disguise, and his use of forensic science skills to solve difficult cases.

Holmes, who first appeared in publication in 1887, was featured in four novels and 56 short stories. The first novel, A Study in Scarlet, appeared in Beeton's Christmas Annual in 1887 and the second, The Sign of the Four, in Lippincott's Monthly Magazine in 1890. The character grew tremendously in popularity with the first series of short stories in Strand Magazine, beginning with A Scandal in Bohemia in 1891; further series of short stories and two novels published in serial form appeared between then and 1927. The stories cover a period from around 1880 up to 1914.

All but four stories are narrated by Holmes's friend and biographer, Dr. John H. Watson; two are narrated by Holmes himself ("The Blanched Soldier" and "The Lion's Mane") and two others are written in the third person ("The Mazarin Stone" and "His Last Bow"). In two stories ("The Musgrave Ritual" and "The Gloria Scott"), Holmes tells Watson the main story from his memories, while Watson becomes the narrator of the frame story. The first and fourth novels, A Study in Scarlet and The Valley of Fear, each include a long interval of omniscient narration recounting events unknown to either Holmes or Watson.

Professor Ivor Norman Richard DaviesFBA, FRHistS (born 8 June 1939) is a leading English historian of Welsh descent, noted for his publications on the history of Europe, Poland, and the United Kingdom.

Davies was born to Richard and Elizabeth Davies in Bolton, Lancashire. He studied in Grenoble, France from 1957 to 1958 and then under A. J. P. Taylor at Magdalen College, Oxford, where he earned a B.A. in History in 1962. He was awarded an M.A. at the University of Sussex in 1966 and also studied in Perugia, Italy. He intended to study for a Ph.D. in the Soviet Union but was denied an entry visa, so instead he went to Kraków, Poland, to study at the Jagiellonian University and do research on the Polish–Soviet War. As this war was denied in the official communist Polish historiography of that time, he was obliged to change the title of his dissertation to The British Foreign Policy towards Poland, 1919–20. After he obtained his Ph.D. in Kraków in 1968, the English text appeared under the title White Eagle, Red Star. The Polish-Soviet War 1919–20 in 1972.

Marion Mitchell Morrison (born Marion Robert Morrison; May 26, 1907 – June 11, 1979), better known by his stage name John Wayne, was an American film actor, director and producer. An Academy Award-winner, Wayne was among the top box office draws for three decades, and was named the all-time top money-making star. An enduring American icon, he epitomized rugged masculinity and is famous for his demeanor, including his distinctive calm voice, walk, and height.

Wayne was born in Winterset, Iowa but his family relocated to the greater Los Angeles area when he was four years old. He found work at local film studios when he lost his football scholarship to USC as a result of a bodysurfing accident. Initially working for the Fox Film Corporation, he mostly appeared in small bit parts. His acting breakthrough came in 1939 with John Ford's Stagecoach, making him an instant star. Wayne would go on to star in 142 pictures, primarily typecast in Western films.

Among his best known films are The Quiet Man (1952), which follows him as an Irish-American boxer and his love affair with a fiery spinster played by Maureen O'Hara; The Searchers (1956), in which he plays a Civil War veteran who seeks out his abducted niece; Rio Bravo (1959), playing a Sheriff with Dean Martin; True Grit (1969), playing a humorous U.S. Marshal who sets out to avenge a man's death in the role that won Wayne an Academy Award; and The Shootist (1976), his final screen performance in which he plays an aging gunslinger battling cancer.
