Catherine Tate (born Catherine Ford on 12 May 1968) is an English actress, writer and comedienne. She has won numerous awards for her work on the sketch comedy series The Catherine Tate Show as well as being nominated for an International Emmy Award and seven BAFTA Awards. Following the success of The Catherine Tate Show, Tate played Donna Noble in the 2006 Christmas special of Doctor Who and later reprised her role, becoming the Doctor's companion for the fourth series in 2008. In 2011, she began a recurring role as Nellie Bertram on The Office.

Tate was born in Bloomsbury and brought up in the Brunswick Centre. Her mother, Josephine, was a florist, and Tate has said that the character of Margaret in The Catherine Tate Show, who shrieks at the slightest of disturbances, is based largely on Josephine.

Tate never knew her father, as he left very early on in her life, and consequently, she was brought up in a female-dominated environment, being cared for by her mother, grandmother and her godparents. As a child, Tate suffered from an obsessive-compulsive disorder which centred on word association. For example, Tate was not able to leave a jumper on the floor or it might have brought misfortune to her mother whose name began with the letter "J" like jumper.

Born to a working class Irish migrant family in Birkenhead, O'Grady went through various jobs in his youth, including working in various bars, for the civil service and for social services, moving around the country to do so. It was whilst living in London in 1978 that he first turned his hand to drag, developing the character of Lily Savage based upon various female relatives of his.

Nancy "Nan" Goldin (born, September 12, 1953, Washington, D.C.) is an American photographer.

Goldin was born in Washington, D.C., and grew up in the Boston, Massachusetts suburb of Lexington, to middle class Jewish parents whose ideas, moderately liberal and progressive, were put to the test when on April 12, 1965 their eldest daughter Barbara Holly, at the age of eighteen, committed suicide. After attending the nearby Lexington High School, she enrolled at the Satya Community School in Lincoln, where a teacher introduced her to the camera in 1968. Goldin was then fifteen years old. Her first solo show, held in Boston in 1973, was based on her photographic journeys among the city's gay and transsexual communities, to which she had been introduced by her friend David Armstrong. Goldin graduated from the School of the Museum of Fine Arts, Boston/Tufts University in 1977/1978, where she had worked mostly with Cibachrome prints.
