Problem: Freddie King (September 3, 1934 - December 28, 1976) was an American blues guitarist and singer. He has been described as one of the "Three Kings" of electric blues guitar, along with Albert King and B.B. King. He was an influential guitarist with hits for Federal Records in the early 1960s. His soulful and powerful voice and distinctive guitar style inspired countless musicians, particularly guitarists (Eric Clapton is a notable example).

According to his birth certificate he was named Fred King, and his parents were Ella Mae King and J. T. Christian. When Freddie was six years old, his mother and his uncle began teaching him to play the guitar. In autumn 1949, he and his family moved from Dallas to the South Side of Chicago. In 1952 King started working in a steel mill. In the same year he married another Texas native, Jessie Burnett. They had seven children. Almost as soon as he had moved to Chicago, King started sneaking into South Side nightclubs, where he heard blues performed by Muddy Waters, Howlin' Wolf, T-Bone Walker, Elmore James, and Sonny Boy Williamson. King formed his first band, the Every Hour Blues Boys, with the guitarist Jimmie Lee Robinson and the drummer Frank "Sonny" Scott. In 1952, while employed at a steel mill, the eighteen-year-old King occasionally worked as a sideman with such bands as the Little Sonny Cooper Band and Earl Payton's Blues Cats. In 1953 he recorded with the latter for Parrot Records, but these recordings were never released. As the 1950s progressed, King played with several of Muddy Waters's sidemen and other Chicago mainstays, including the guitarists Jimmy Rogers, Robert Lockwood Jr., Eddie Taylor, and Hound Dog Taylor; the bassist Willie Dixon; the pianist Memphis Slim; and the harmonicist Little Walter. In 1956 he cut his first record as a leader, for El-Bee Records. The A-side was "Country Boy", a duet with Margaret Whitfield. The B-side was a King vocal. Both tracks feature the guitar of Robert Lockwood, Jr., who during these years was also adding rhythm backing and fills to Little Walter's records. King was repeatedly rejected in auditions for the South Side's Chess Records, the premier blues label, which was the home of Muddy Waters, Howlin' Wolf, and Little Walter. The complaint was that King sang too much like B.B. King. A newer blues scene, lively with nightclubs and upstart record companies, was burgeoning on the West Side, though. The bassist and producer Willie Dixon, during a period of estrangement from Chess in the late 1950s, asked King to come to Cobra Records for a session, but the results have never been heard. Meanwhile, King established himself as perhaps the biggest musical force on the West Side. He played along with Magic Sam and reputedly played backing guitar, uncredited, on some of Sam's tracks for Mel London's Chief and Age labels, though King does not stand out on them.

Problem: Terence Joseph "Terry" Nation (8 August 1930 - 9 March 1997) was a Welsh television writer and novelist. Nation first made his name as a comedy writer before becoming a prolific writer for drama, working on many of the most popular British series of the 1960s and 1970s. He made a significant contribution to the long-running BBC science-fiction series Doctor Who from its outset, creating the villainous Daleks which established its early popularity and later devising the recurring character of Davros.

Prior to this, Nation had declined an offer from scriptwriter David Whitaker to write for a new science-fiction programme that was entering production at the BBC; Whitaker had been impressed by a script that Nation had written for the ABC anthology series Out of this World. Now unemployed, and with a young family to support, Nation contacted Whitaker and accepted the offer, writing the second Doctor Who serial, The Daleks (also known as The Mutants and The Dead Planet). The serial introduced the eponymous extraterrestrial villains that would quickly become the series' most popular and enduring monsters, and resulted in a major merchandising success for the BBC. Having risen in the public consciousness, Nation went on to contribute further scripts to Doctor Who. In 1965, Nation and Dennis Spooner co-wrote the 12-part serial The Daleks' Master Plan, after which Nation, who still held the copyright to the Daleks, attempted to launch a Dalek spin-off TV series in the United States. Various other Dalek tie-in material appeared, including comic strips in the children's weekly TV Century 21 and annuals; such material was frequently credited to Nation, even when written by others. Between 1966 and 1972, appearances by the Daleks in Doctor Who became less frequent and were written for the series by other authors. In 1973, following an eight-year absence from scriptwriting for the series, Nation returned to writing for the Daleks on Doctor Who with the Third Doctor serial Planet of the Daleks. In 1998, readers of Doctor Who Magazine voted Nation's 1975 serial Genesis of the Daleks the greatest Doctor Who story of all time. In the story, Nation introduced the character of Davros, the creator of the Daleks, who went on to appear in further storylines. Nation also wrote two non-Dalek scripts for Doctor Who, The Keys of Marinus in 1964, which introduced the Voord and The Android Invasion in 1975, which introduced the Kraal. During this time, Nation also worked in commercial TV, contributing scripts to series such as The Avengers, The Baron, The Champions, Department S, The Persuaders! and The Saint. Nation's work on Doctor Who was the subject of the documentary Terror Nation, a special feature on the BBC DVD release of the serial Destiny of the Daleks.
