Background: Dame Agatha Mary Clarissa Christie, Lady Mallowan,  (nee Miller; 15 September 1890 - 12 January 1976) was an English writer. She is known for her 66 detective novels and 14 short story collections, particularly those revolving around her fictional detectives Hercule Poirot and Miss Marple. Christie also wrote the world's longest-running play, a murder mystery, The Mousetrap, and six romances under the name Mary Westmacott. In 1971 she was appointed a Dame Commander of the Order of the British Empire (DBE) for her contribution to literature.
Context: Christie had long been a fan of detective novels, having enjoyed Wilkie Collins's The Woman in White and The Moonstone, as well as Sir Arthur Conan Doyle's early Sherlock Holmes stories. She wrote her own detective novel, The Mysterious Affair at Styles, featuring Hercule Poirot, a former Belgian police officer noted for his twirly large "magnificent moustaches" and egg-shaped head. Poirot had taken refuge in Britain after Germany invaded Belgium. Christie's inspiration for the character stemmed from real Belgian refugees who were living in Torquay and the Belgian soldiers whom she helped treat as a volunteer nurse in Torquay during the First World War.  Agatha began working on The Mysterious Affair at Styles in 1916, writing most of it on Dartmoor. Her original manuscript was rejected by such publishing companies as Hodder and Stoughton and Methuen. After keeping the submission for several months, John Lane at The Bodley Head offered to accept it, provided that Christie change the ending. She did so, and signed a contract which she later felt was exploitative. It was finally published in 1920.  Christie, meanwhile, settled into married life, giving birth to her only child, daughter Rosalind Margaret Hicks, in August 1919 at Ashfield, where the couple spent much of their time, having few friends in London. Archie left the Air Force at the end of the war and started working in the City financial sector at a relatively low salary, though they still employed a maid.  Christie's second novel, The Secret Adversary (1922), featured a new detective couple Tommy and Tuppence, again published by The Bodley Head. It earned her PS50. A third novel again featured Poirot, Murder on the Links (1923), as did short stories commissioned by Bruce Ingram, editor of The Sketch magazine. In order to tour the world promoting the British Empire Exhibition, the couple left their daughter Rosalind with Agatha's mother and sister. They travelled to South Africa, Australia, New Zealand, and Hawaii.  They learned to surf prone in South Africa; then, in Waikiki, they were among the first Britons to surf standing up.

Background: Julian Paul Assange (; ne Hawkins; born 3 July 1971) is an Australian computer programmer and the editor of WikiLeaks. Assange founded WikiLeaks in 2006, but came to international attention in 2010, when WikiLeaks published a series of leaks provided by Chelsea Manning. These leaks included the Collateral Murder video (April 2010), the Afghanistan war logs (July 2010), the Iraq war logs (October 2010), and CableGate (November 2010). Following the 2010 leaks, the federal government of the United States launched a criminal investigation into WikiLeaks and asked allied nations for assistance.
Context: Assange was born in Townsville, Queensland, to Christine Ann Hawkins (b. 1951), a visual artist, and John Shipton, an anti-war activist and builder. The couple had separated before Assange was born.  When he was a year old, his mother married Richard Brett Assange, an actor, with whom she ran a small theatre company. They divorced around 1979. Christine Assange then became involved with Leif Meynell, also known as Leif Hamilton, a member of Australian cult The Family, with whom she had a son before the couple broke up in 1982. Assange had a nomadic childhood, and had lived in over thirty Australian towns by the time he reached his mid-teens, when he settled with his mother and half-brother in Melbourne, Victoria.  He attended many schools, including Goolmangar Primary School in New South Wales (1979-1983) and Townsville State High School, as well as being schooled at home. He studied programming, mathematics, and physics at Central Queensland University (1994) and the University of Melbourne (2003-2006), but did not complete a degree.  While in his teens, Assange married a woman named Teresa, and in 1989 they had a son, Daniel Assange, now a software designer. The couple separated and initially disputed custody of their child. Assange was Daniel's primary caregiver for much of his childhood. In an open letter to French President Francois Hollande, Assange stated his youngest child lives in France with his mother. He also said that his family had faced death threats and harassment because of his work, forcing them to change identities and reduce contact with him.

Answer: 

Background: Buffalo Springfield was a Canadian-American rock band active from 1966 to 1968 whose most prominent members were Stephen Stills, Neil Young, and Richie Furay. The band released three albums and several singles, including "For What It's Worth". The band combined elements of folk and country music with British invasion and psychedelic-rock influences, and, along with the Byrds, were part of the early development of folk-rock. With a name taken from a brand of steamroller, Buffalo Springfield formed in Los Angeles in 1966 with Stills (guitar, keyboards, vocals), Dewey Martin (drums, vocals), Bruce Palmer (electric bass), Furay (guitar, vocals), and Young (guitar, harmonica, piano, vocals).
Context: Neil Young and Stephen Stills met in 1965, at the Fourth Dimension in Thunder Bay, Ontario. Young was there with the Squires, a Winnipeg group he had been leading since February 1963, and Stills was on tour with The Company, a spin-off from the Au Go Go Singers. When Stills' band broke up at the end of that tour, he moved to the West Coast, where he worked as a session musician and auditioned unsuccessfully for, among other bands, the Monkees. Told by record producer Barry Friedman there would be work available if he could assemble a band, Stills invited fellow Au Go Go Singers alumnus Richie Furay and former Squires bass player Ken Koblun to come join him in California. Both agreed, although Koblun chose to leave before very long and joined the group 3's a Crowd.  In early 1966 in Toronto, Young met Bruce Palmer, a Canadian who was playing bass for a group called the Mynah Birds. In need of a lead guitarist, Palmer invited Young to join the group, and Young accepted. The Mynah Birds were set to record an album for Motown Records when their singer Ricky James Matthews--James Ambrose Johnson, Jr., later known as Rick James--was tracked down and arrested by the U.S. Navy for being AWOL. With their record deal canceled, Young and Palmer headed for Los Angeles, where they encountered Stills.  Drummer Dewey Martin, who had played with garage rock group the Standells and country artists such as Patsy Cline and the Dillards, joined at the suggestion of the Byrds' manager, Jim Dickson. The group's name was taken from a brand of steamroller made by the Buffalo-Springfield Roller Company. The new group debuted on April 11, 1966, at The Troubadour in Hollywood. A few days later, they began a short tour of California as the opening act for the Dillards and the Byrds.
