Background: 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.
Context: 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.
Question: How did people percieve him?
Answer: ). He is well-educated

Background: Stephen Ray Vaughan (October 3, 1954 - August 27, 1990) was an American musician, singer, songwriter, and record producer. In spite of a short-lived mainstream career spanning seven years, he was one of the most influential guitarists in the revival of blues in the 1980s. AllMusic describes him as "a rocking powerhouse of a guitarist who gave blues a burst of momentum in the '80s, with influence still felt long after his tragic death." Born and raised in Dallas, Texas, Vaughan began playing guitar at the age of seven, inspired by his older brother Jimmie.
Context: In September 1970, Vaughan made his first studio recordings with the band Cast of Thousands, which included future actor Stephen Tobolowsky. They recorded two songs, "Red, White and Blue" and "I Heard a Voice Last Night", for a compilation album, A New Hi, that featured various teenage bands from Dallas. In late January 1971, feeling confined by playing pop hits with Liberation, Vaughan formed his own band, Blackbird. After growing tired of the Dallas music scene, he dropped out of school and moved with the band to Austin, Texas, which had more liberal and tolerant audiences. There, Vaughan initially took residence at the Rolling Hills Country Club, a venue that would later become the Soap Creek Saloon. Blackbird played at several clubs in Austin and opened shows for bands such as Sugarloaf, Wishbone Ash, and Zephyr, but could not maintain a consistent lineup. In early December 1972, Vaughan left Blackbird and joined a rock band named Krackerjack; he performed with them for less than three months.  In March 1973, Vaughan joined Marc Benno's band, the Nightcrawlers, after meeting Benno at a jam session years before. The band featured vocalist Doyle Bramhall, who met Vaughan when he was twelve years old. The next month, the Nightcrawlers recorded an album at Sunset Sound Recorders in Hollywood for A&M Records. While the album was rejected by A&M, it included Vaughan's first songwriting efforts, "Dirty Pool" and "Crawlin'". Soon afterward, he and the Nightcrawlers traveled back to Austin without Benno. In mid-1973, they signed a contract with Bill Ham, manager for ZZ Top, and played various gigs across the South, though many of them were disastrous. Ham left the band stranded in Mississippi without any way to make it back home and demanded reimbursement from Vaughan for equipment expenses; Ham was never reimbursed.  In 1975, Vaughan joined a six-piece band called Paul Ray and the Cobras that included guitarist Denny Freeman and saxophonist Joe Sublett. For the next two-and-a-half years, he earned a living performing weekly at a popular venue in town, the Soap Creek Saloon, and ultimately the newly opened Antone's, widely known as Austin's "home of the blues". In late 1976, Vaughan recorded a single with them, "Other Days" as the A-side and "Texas Clover" as the B-side. Playing guitar on both tracks, the single was released on February 7, 1977. In March, readers of the Austin Sun voted them as Band of the Year. In addition to playing with the Cobras, Vaughan jammed with many of his influences at Antone's, including Buddy Guy, Hubert Sumlin, Jimmy Rogers, Lightnin' Hopkins, and Albert King.  Vaughan toured with the Cobras during much of 1977, but near the end of September, after they decided to strive for a mainstream musical direction, he left the band and formed Triple Threat Revue, which included singer Lou Ann Barton, bassist W. C. Clark, and drummer Fredde Pharaoh. In January 1978, they recorded four songs in Austin, including Vaughan's composition "I'm Cryin'". The thirty-minute audio recording marks the only known studio recording of the band.
