Question:
Cudi was born Scott Ramon Seguro Mescudi on January 30, 1984, in Cleveland, Ohio, and grew up in Shaker Heights and Solon. He is the youngest of four children, with two brothers, Domingo and Dean, and a sister, Maisha. His mother, Elsie Harriet (Banks), is a middle-school choir teacher at Roxboro Middle School in Cleveland Heights, Ohio. His father, Lindberg Styles Mescudi, was a house painter, substitute teacher and World War II Air Force veteran.
Kid Cudi's musical style has been described as "an atmospheric take on melodic rap, with a dollop of charming, off-key singing". He has also been called "introspective, with the ability to lay his insecurities on record and expose his fallibility." In 2015, Kris Ex of Billboard, wrote "he's always been an emotional artist, dealing with expansive and nebulous feelings in acute and often destructive ways." Kid Cudi's sound is what inspired and led Kanye West to create his cathartic 808s & Heartbreak (2008), with West later stating that he and Cudi were "the originators of the style, kinda like what Alexander McQueen is to fashion.... Everything else is just Zara and H&M." West also complimented Cudi by saying, "His writing is just so pure and natural and important." In March 2014, Cudi talked about wanting to provide guidance for young listeners with his music: "my mission statement since day one [...] all I wanted to do was help kids not feel alone, and stop committing suicide." In a 2013 article for The BoomBox, the author wrote: "On [A Kid Named Cudi], Cudi raps and croons over samples and interpolations of Gnarls Barkley, Paul Simon, Band of Horses, J Dilla, Nosaj Thing, N.E.R.D. and Outkast. He melded indie rock, electronica and dubstep seamlessly with hip-hop without pandering or reaching. Before Drake broke through with 2009's So Far Gone, rapping and singing over Swedish indie poppers Lykke Li and Peter Bjorn and John, Cudi tweaked with multi-genre covers and seamless transitions between singing and rapping." In a 2009 interview with HipHopDX, when speaking on his debut album Cudi stated: "Well one thing I wanted to do was combine sounds that really bring out intense moods." Kid Cudi's music has also been described as trip hop. Furthermore, he is known for harmonizing and humming in his music, which helps formulate his signature sound. On 2011's WZRD and 2015's Speedin' Bullet 2 Heaven, Cudi incorporated the use of screamed vocals, and can be heard yodeling on his 2016 album Passion, Pain & Demon Slayin'. Throughout the years he has also incorporated elements of psychedelia, R&B, electronica, synthpop and grunge, in his music.

input: Asimov was born on an unknown day between October 4, 1919 and January 2, 1920, inclusive. Asimov himself celebrated it on January 2. Asimov's parents were Anna Rachel (nee Berman) and Judah Asimov, a family of Jewish millers. He was named Isaac after his mother's father, Isaac Berman. When he was born, his family lived in Petrovichi near Klimovichi, which was then Gomel Governorate in the Russian Soviet Federative Socialist Republic (now Smolensk Oblast, Russia). Asimov wrote of his father, "My father, for all his education as an Orthodox Jew, was not Orthodox in his heart", noting that "he didn't recite the myriad prayers prescribed for every action, and he never made any attempt to teach them to me". In 1921, Asimov and 16 other children in Petrovichi caught double pneumonia. Only Asimov survived. He later had two younger siblings: a sister, Marcia (born Manya, June 17, 1922 - April 2, 2011), and a brother, Stanley (July 25, 1929 - August 16, 1995), who was vice-president of New York Newsday. His family emigrated to the United States when he was three years old. Since his parents always spoke Yiddish and English with him, he never learned Russian, but he remained fluent in Yiddish as well as English. Growing up in Brooklyn, New York, Asimov taught himself to read at the age of five, and his mother got him into first grade a year early by claiming he was born on September 7, 1919. In third grade he learned about the "error" and insisted on an official correction of the date to January 2. After becoming established in the U.S., his parents owned a succession of candy stores, in which everyone in the family was expected to work. The candy stores sold newspapers and magazines, a fact that Asimov credited as a major influence in his lifelong love of the written word, as it presented him with an unending supply of new reading material as a child that he could not have otherwise afforded. He became a naturalized U.S. citizen in 1928 at the age of eight.

Answer the question at the end by quoting:

David Gaub McCullough (; born July 7, 1933) is an American author, narrator, historian, and lecturer. He is a two-time winner of the Pulitzer Prize and the National Book Award and a recipient of the Presidential Medal of Freedom, the United States' highest civilian award. Born and raised in Pittsburgh, McCullough earned a degree in English literature from Yale University.
McCullough was born in the Point Breeze neighborhood of Pittsburgh, Pennsylvania, the son of Ruth (nee Rankin) and Christian Hax McCullough. He is of Scots-Irish descent. He was educated at Linden Avenue Grade School and Shady Side Academy, in his hometown of Pittsburgh. One of four sons, McCullough had a "marvelous" childhood with a wide range of interests, including sports and drawing cartoons. McCullough's parents and his grandmother, who read to him often, introduced him to books at an early age. His parents often talked about history, a topic he says should be discussed more often. McCullough "loved school, every day"; he contemplated many career choices, ranging from architect, actor, painter, writer, to lawyer, and contemplated attending medical school for a time. In 1951, McCullough began attending Yale University. He said that it was a "privilege" to study English at Yale because of faculty members such as John O'Hara, John Hersey, Robert Penn Warren, and Brendan Gill. McCullough occasionally ate lunch with the Pulitzer Prize-winning novelist and playwright Thornton Wilder. Wilder, says McCullough, taught him that a competent writer maintains "an air of freedom" in the storyline, so that a reader will not anticipate the outcome, even if the book is non-fiction. While at Yale, he became a member of Skull and Bones. He served apprenticeships at Time, Life, the United States Information Agency, and American Heritage, where he enjoyed research. "Once I discovered the endless fascination of doing the research and of doing the writing, I knew I had found what I wanted to do in my life." While attending Yale, McCullough studied Arts and earned his bachelor's degree in English, with the intention of becoming a fiction writer or playwright. He graduated with honors in English literature (1955).
