Derbyshire (ⁱ/ˈdɑrbɨʃə/ DAR-bi-shər or /ˈdɑrbɪʃɪər/ DAR-bi-sheer; abbreviated Derbys. or Derbs.) is a county in the East Midlands of England. A substantial portion of the Peak District National Park lies within Derbyshire. The southern extremity of the Pennine range of hills extends into the north of the county. The county contains within its boundary of approximately 225 miles part of the National Forest. It borders on Greater Manchester to the northwest, West Yorkshire to the north, South Yorkshire to the northeast, Nottinghamshire to the east, Leicestershire to the southeast, Staffordshire to the west and southwest and Cheshire also to the west. In 2003 the Ordnance Survey placed Church Flatts farm, near Coton in the Elms, as the furthest point from the sea in Great Britain.

The city of Derby is now a unitary authority area, but remains part of the ceremonial county of Derbyshire. The non-metropolitan county contains 30 towns with between 10,000 and 100,000 inhabitants. There is a large amount of sparsely populated agricultural upland: 75% of the population live in 25% of the area.^{[citation needed]}

John Derbyshire (born June 3, 1945) is a British-American writer, journalist and commentator. He formerly wrote a column in National Review. He has also written for the New English Review. These columns cover a broad range of political-cultural topics, including immigration, China, history, mathematics, and race. Derbyshire's 1996 novel, Seeing Calvin Coolidge in a Dream, was a New York Times "Notable Book of the Year". His 2004 non-fiction book, Prime Obsession, won the Mathematical Association of America's inaugural Euler Book Prize. A new political book, We Are Doomed: Reclaiming Conservative Pessimism, was released in September 2009.

Derbyshire attended the Northampton School for Boys and graduated from University College London, where he studied mathematics. Before turning to writing full-time, he worked on Wall Street as a computer programmer.

Derbyshire has differed from his fellow writers at National Review on many subjects. For example, Derbyshire supported Michael Schiavo's position in the Terri Schiavo case, ridiculed George W. Bush's "itty-bitty tax cut, paid for by dumping a slew of federal debt on your children and grandchildren", has derided Bush in general for being too sure of his religious convictions and for his "rich-kid-ness", dismisses small-government conservatism as unlikely to ever take hold (although he is not unsympathetic to it), has called for immediate U.S. withdrawal from Iraq (but favored the invasion), opposes market reforms or any other changes in Social Security, is pro-choice on abortion, supports euthanasia in a fairly wide range of circumstances, and has suggested that he might (in a time of international crisis) vote for Hillary Clinton as president.

Delia Ann Derbyshire (5 May 1937 – 3 July 2001) was an English musician and composer of electronic music and musique concrète. She is best known for her electronic realisation of Ron Grainer's theme music to the British science fiction television series Doctor Who and for her work with the BBC Radiophonic Workshop.

Derbyshire was born in Coventry, daughter of Emma (née Dawson) and Edward Derbyshire. of Cedars Avenue, Coundon, Coventry, a sheet-metal worker. She had one sibling, a sister, who died young. Her father died in 1965 and her mother in 1994.

During the Second World War, immediately after the Coventry Blitz in 1940, she was moved to Preston, Lancashire for safety, where her parents had moved from and where most of her surviving relatives still live. She was very bright and, by the age of four, was teaching others in her class to read and write in primary school, but said "The radio was my education". Her parents bought her a piano when she was eight years old. Educated at Barr's Hill Grammar School from 1948 to 1956, she was accepted at both Oxford and Cambridge, "quite something for a working class girl in the 'fifties, where only one in 10 (students) were female", won a scholarship to study mathematics at Girton College, Cambridge but, apart from some success in the mathematical theory of electricity, she claims she did badly and after one year switched to music, graduating in 1959 with an MA in Mathematics and Music and specialising in medieval and modern music history. Her other principal qualification was LRAM in pianoforte.

Matthew Anthony "Matt" Derbyshire (born 14 April 1986) is an English footballer who plays for Nottingham Forest. He is a striker, who played for Blackburn Rovers for five years, and had loan spells with Plymouth Argyle, Wrexham and Olympiacos, before joining the latter club on a permanent basis in 2009.

Derbyshire was born in Blackburn and attended Our Lady and St John R.C. High School in the town. He played football as a youngster for Darwen before joining Great Harwood Town in 2002. He scored his first goal for the club's first team as a 16-year-old, in October 2002, and by the time he left in November 2003, he had scored 26, of which 21 had come in the North West Counties League, and 18 in his last nine appearances.

He joined his boyhood club, Blackburn Rovers, in November 2003 for a £20,000 fee, a club record for Great Harwood. He had previously worked in the club's community department, coaching young children. He rejected a move to Manchester United in favour of Blackburn as he felt his first team opportunities would be greater there.
