Answer by taking a quote from the following article:

George Gideon Oliver Osborne  (born 23 May 1971) is a British Conservative Party politician, who was Member of Parliament (MP) for Tatton from June 2001 until he stood down on 3 May 2017. He served as Chancellor of the Exchequer under Prime Minister David Cameron from 2010 to 2016. He has been editor of the London Evening Standard since May 2017. Osborne worked briefly as a freelancer for The Daily Telegraph before joining the Conservative Research Department in 1994 and becoming head of its political section.

George Osborne was born in Paddington, London, as Gideon Oliver Osborne; he decided when he was 13 to be known by the additional first name of 'George'. In an interview in July 2005, he said: "It was my small act of rebellion. I never liked it [the name 'Gideon']. When I finally told my mother she said, 'Nor do I'. So I decided to be George after my grandfather, who was a war hero. Life was easier as a George; it was a straightforward name." He is the eldest of four boys. His father Sir Peter Osborne co-founded the firm of fabric and wallpaper designers Osborne & Little. His mother is Felicity Alexandra Loxton-Peacock, the daughter of Hungarian-born artist Clarisse Loxton-Peacock (nee Feher).  Osborne was educated at independent schools: Norland Place School, Colet Court and St Paul's School. In 1990 he was awarded a demyship at Magdalen College, Oxford, where in 1993 he received a 2:1 bachelor's degree in Modern History. Whilst there, he was a member of the Bullingdon Club. He also attended Davidson College in North Carolina for a semester, as a Dean Rusk Scholar.  In 1993, Osborne intended to pursue a career in journalism. He was shortlisted for, but failed to gain a place on, The Times' trainee scheme; he also applied to The Economist, where he was interviewed and rejected by Gideon Rachman. In the end, he had to settle for freelance work on the Peterborough diary column of The Daily Telegraph. One of his Oxford friends, journalist George Bridges, alerted Osborne some time later to a research vacancy at Conservative Central Office.
