Who was the first female artist to achieve a UK number-one with a self-written song?

Catherine "Kate" Bush, CBE (born 30 July 1958) is an English singer-songwriter, musician and record producer. She first came to note in 1978 when, at the age of 19, she topped the UK Singles Chart for four weeks with her debut single "Wuthering Heights", becoming the first female artist to achieve a UK number-one with a self-written song. She has since released twenty-five UK Top 40 singles, including the top ten hits "The Man with the Child in His Eyes", "Babooshka", "Running Up That Hill", "Don't Give Up" (a duet with Peter Gabriel) and "King of the Mountain". She has released ten studio albums, all of which reached the UK Top 10, including the UK number-one albums Never for Ever (1980) and Hounds of Love (1985).

Bush has received widespread critical acclaim for her eclectic and idiosyncratic music as well as her theatrical performances. She has been nominated 13 times for British Phonographic Industry accolades, and in 1987 she won a Brit Award for Best British Female Artist. During the course of her career, she has also been nominated for three Grammy Awards. In 2002, she was recognised with an Ivor Novello Award for Outstanding Contribution to British Music. Bush was appointed Commander of the Order of the British Empire (CBE) in the 2013 New Year Honours for services to music.
