John Crank (6 February 1916 – 3 October 2006) was a mathematical physicist, best known for his work on the numerical solution of partial differential equations.

Crank was born in Hindley in Lancashire, England. His father was a carpenter's pattern-maker. Crank studied at Manchester University from 1934 to 1938, where he was awarded a BSc and MSc as a student of Lawrence Bragg and Douglas Hartree. In 1953, Manchester University awarded him a DSc.

He worked on ballistics during the Second World War, and was then a mathematical physicist at Courtaulds Fundamental Research Laboratory from 1945 to 1957. In 1957, he was appointed as the first Head of Department of Mathematics at Brunel College in Acton. He served two terms of office as Vice-Principal of Brunel before his retirement in 1981, when he was granted the title of Professor Emeritus.

Crank's main work was on the numerical solution of partial differential equations and, in particular, the solution of heat-conduction problems. He is best known for his work with Phyllis Nicolson on the heat equation, which resulted in the Crank–Nicolson method.

DeAndre Cortez Way (born July 28, 1990), better known by his stage name Soulja Boy Tell 'Em, or simply Soulja Boy, is an American rapper, record producer, actor, and entrepreneur.

In September 2007, his single "Crank That (Soulja Boy)" reached number one on the Billboard Hot 100. The single was initially self-published on the internet, and it later became a number-one hit in the United States for seven non-consecutive weeks starting in September 2007. On August 17 Way was listed at #18 on the Forbes list of Hip-Hop Cash Kings of 2010 earning $7 million for that year.

Way has currently released three studio albums and one independent album: his debut studio album Souljaboytellem.com (2007) was certified platinum by the RIAA. However, his next two albums, iSouljaBoyTellem (2008) and The DeAndre Way (2010) did not match the commercial success of his debut, the latter only selling 100,000 copies, despite the success of several singles across both albums, such as "Kiss Me Thru the Phone" and "Turn My Swag On" (iSouljaBoyTellem) and "Pretty Boy Swag" (The DeAndre Way).

John Franklin Candy (October 31, 1950 – March 4, 1994) was a Canadian actor and comedian. He rose to fame as a member of the Toronto branch of The Second City and its related Second City Television series, and through his appearances in comedy films such as Stripes, Splash, Cool Runnings, The Great Outdoors, Spaceballs, and Uncle Buck. One of his most renowned onscreen performances was as Del Griffith, the loquacious, on-the-move shower-curtain ring salesman in the John Hughes comedy Planes, Trains and Automobiles.

Candy was born in Newmarket, Ontario in 1950. The son of Sidney James Candy and his wife Evangeline (Aker) Candy, he was raised in a working-class Roman Catholic family. His grandmother was Polish. Candy graduated from Neil McNeil High School, an all-boys Catholic public school in Toronto, where he played football.

Candy's first movie role was a small uncredited appearance in the 1973 film Class of '44. He appeared in several other low-budget films during the 1970s, including the bank-robbery thriller The Silent Partner with Christopher Plummer and Elliott Gould. In 1976, Candy played a supporting role (with Rick Moranis) on Peter Gzowski's short-lived, late-night television talk show, Ninety Minutes Live. That same year, as a member of Toronto's branch of The Second City, he gained wide North American popularity, which grew when he became a cast member on the influential Toronto-based comedy-variety show Second City Television (SCTV). NBC picked the show up in 1981 and it quickly became a fan favorite. It had won Emmy Awards for the show's writing in 1981 and 1982.

John Creasey MBE (17 September 1908 – 9 June 1973) was an English crime and science fiction writer.

The author of more than 600 novels, John Creasey published them using 28 different pseudonyms, including:

Westerns under the names of Ken Ranger, Tex Riley, William K. Reilly, and Jimmy Wilde. Romantic novels under the names of Margaret Cooke, M.E. Cooke, and Elise Fecamps.

He created several characters which are now famous, such as The Toff, Commander George Gideon of Scotland Yard, Inspector Roger West, The Baron, and Doctor Stanislaus Alexander Palfrey. The most popular of these was Gideon of Scotland Yard, who was the basis for the television series Gideon's Way and for the John Ford movie Gideon of Scotland Yard (1958), also known by its British title Gideon's Day. The Baron character was made into a 1960s TV series starring Steve Forrest as The Baron.

John Creasey was born in Southfields, Surrey, to a working-class family. He was the seventh of nine children of Ruth and Joseph Creasey, a poor coach maker. Creasey was educated at Fulhan Elementary School and Sloane School, both in London. From 1923 to 1935 he worked various clerical, factory, and sales jobs while trying to establish himself as a writer. After a number of rejections, Creasey's first book was published in 1930. His first crime novel, Seven Times Seven, was published in January, 1932 by Melrose. It was a story about a gang of criminals. In 1935 he became a full-time writer. In 1937 alone, twenty-nine of his books were published. A phenomenally fast writer, he once suggested that he could be shut up in a glass-box and write there a whole book.

John Robert Parker Ravenscroft, OBE (30 August 1939 – 25 October 2004), known professionally as John Peel, was an English disc jockey, radio presenter, record producer and journalist. He was the longest-serving of the original BBC Radio 1 DJs, broadcasting regularly from 1967 until his death in 2004. He was known for his eclectic taste in music and his honest and warm broadcasting style.

He was one of the first broadcasters to play psychedelic rock and progressive rock records on British radio, and he is widely acknowledged for promoting artists working in various genres, including pop, reggae, indie rock, alternative rock, punk, hardcore punk, breakcore, grindcore, death metal, British hip hop, and dance music.

Peel's Radio 1 shows were notable for the regular 'Peel sessions', which usually consisted of four songs recorded by an artist live in the BBC's studios, and which often provided the first major national coverage to bands that later would achieve great fame. (These 'sessions' are similar to 'Live Lounge' sessions recorded today for the station.) Another popular feature of his shows was the annual Festive Fifty countdown of his listeners' favourite records of the year.
