Some context: Joshua Lawrence Chamberlain (born Lawrence Joshua Chamberlain, September 8, 1828 - February 24, 1914) was an American college professor from the State of Maine, who volunteered during the American Civil War to join the Union Army. He became a highly respected and decorated Union officer, reaching the rank of brigadier general (and brevet major general). He is best known for his gallantry at the Battle of Gettysburg, for which he was awarded the Medal of Honor. Chamberlain was commissioned a lieutenant colonel in the 20th Maine Volunteer Infantry Regiment in 1862 and fought at the Battle of Fredericksburg.
Chamberlain was born in Brewer, Maine, the son of Sarah Dupee (nee Brastow) and Joshua Chamberlain on September 8, 1828. Chamberlain was of English ancestry, and could trace his family line back to twelfth century England, during the reign of King Stephen. He was the oldest of five children. It is said that he was his mother's favorite while his father was tough on him. He was very involved in his church, mostly singing in the choir. His mother encouraged him to become a preacher while his father wanted him to join the military, but he felt a reluctance towards both options. He suffered a speech impediment until shortly after graduating from Bowdoin College. He entered Bowdoin College in Brunswick, Maine, in 1848 with the help of a local tutor, professor William Hyde. Chamberlain learned to read Ancient Greek and Latin in order to pass the entrance exam. While at Bowdoin he met many people who would influence his life, including Harriet Beecher Stowe, the wife of Bowdoin professor Calvin Stowe. Chamberlain would often go to listen to her read passages from what would later become her celebrated novel, Uncle Tom's Cabin. He also joined the Peucinian Society, a group of students with Federalist leanings. A member of the Phi Beta Kappa academic honor society and a brother of the Alpha Delta Phi fraternity, Chamberlain graduated in 1852.  He married Fanny Adams, cousin and adopted daughter of a local clergyman, in 1855, and they had five children, one of whom was born too prematurely to survive and two of whom died in infancy. Chamberlain studied for three additional years at Bangor Theological Seminary in Bangor, Maine, returned to Bowdoin, and began a career in education as a professor of rhetoric. He eventually went on to teach every subject in the curriculum with the exception of science and mathematics. In 1861 he was appointed Professor of Modern Languages. He was fluent in nine languages other than English: Greek, Latin, Spanish, German, French, Italian, Arabic, Hebrew, and Syriac.  Chamberlain's great-grandfathers were soldiers in the American Revolutionary War. One, Franklin Chamberlain, was a sergeant at the Siege of Yorktown. His grandfather, also named Joshua Chamberlain, was a colonel in the local militia during the War of 1812 and was court-martialed (but exonerated) for his part in the humiliating Battle of Hampden, which led to the sacking of Bangor and Brewer by British forces. His father also had served during the abortive Aroostook War of 1839.

Some context: Dr. Hannibal Lecter is a character in a series of suspense novels by Thomas Harris. Lecter was introduced in the 1981 thriller novel Red Dragon as a forensic psychiatrist and cannibalistic serial killer. The novel and its sequel, The Silence of the Lambs, feature Lecter as one of the primary antagonists after the two serial killers in both novels. In the third novel, Hannibal, Lecter becomes a protagonist.
Red Dragon firmly states that Lecter does not fit any known psychological profile. In The Silence of the Lambs, Lecter's keeper, Dr. Frederick Chilton, claims that Lecter is a "pure sociopath" ("pure psychopath" in the film adaptation). In the novel Red Dragon, protagonist Will Graham says that Lecter has no conscience and tortured animals as a child, but does not exhibit any other of the criteria traditionally associated with psychopathy; Graham explains that psychiatrists refer to Lecter as a sociopath because "they don't know what else to call him". In the film adaptation of The Silence of the Lambs, protagonist Clarice Starling says of Lecter, "They don't have a name for what he is." In the novel The Silence of the Lambs, Barney Matthews, an orderly at the facility where Lecter is imprisoned, claims that the only thing Lecter fears is boredom.  Lecter's pathology is explored in greater detail in Hannibal and Hannibal Rising, which explains that he was traumatized as a child in Lithuania in 1944 when he witnessed the murder and cannibalism of his beloved sister, Mischa, by a group of deserting Lithuanian Hilfswillige, one of whom claimed that Lecter unwillingly ate his sister as well.  All media in which Lecter appears portray him as intellectually brilliant, cultured and sophisticated, with refined tastes in art, music and cuisine. He is frequently depicted preparing gourmet meals from his victims' flesh, the most famous example being his admission that he once ate a census taker's liver "with some fava beans and a nice Chianti" (a "big Amarone" in the novel). He is well-educated in Anatomy, Chemistry and Physics and also speaks several languages, including Italian, German, Russian, Polish, French, Spanish, and, to some extent, Japanese. He is deeply offended by rudeness, and frequently kills people who have bad manners. Prior to his capture and imprisonment, he was a member of Baltimore, Maryland's social elite, and a sitting member of the Baltimore Philharmonic Orchestra's board of directors.  In The Silence of the Lambs, Lecter is described through Starling's eyes: "small, sleek, and in his hands and arms she saw wiry strength like her own". The novel also reveals that Lecter's left hand has a condition called mid ray duplication polydactyly, i.e. a duplicated middle finger. In Hannibal, he performs plastic surgery on his own face on several occasions, and removes his extra digit. Lecter's eyes are a shade of maroon, and reflect the light in "pinpoints of red". He has small white teeth and dark, slicked-back hair with a widow's peak. He also has a keen sense of smell; in The Silence of the Lambs, he is able to identify through a plexiglass window with small holes the brand of perfume that Starling wore the day before. At one point, when Hannibal points out Clarice must have gotten a bruise lately, she suddenly remembers she has a band-aid on her covered leg, so she assumes he must have smelled it. He has an eidetic memory with which he has constructed in his mind an elaborate "memory palace" with which he relives memories and sensations in rich detail.
