Gibb began to sing with his brothers at just 6 years old, performing in local theatres and appearing during intermissions at cinemas in Manchester during the mid-1950s. They continued performing in Australia, achieving their first Australian number one single with 'Spicks and Specks' in 1965. Shortly afterwards, the band returned to the UK and signed a record deal with Polydor, achieving their first international hits with 'New York Mining Disaster 1941' and 'To Love Somebody'.
There were reported tensions during this early period of success, which ultimately led to Gibb leaving the group as he believed his brother Barry was being favoured as lead vocalist. After brief solo success with 'Saved by the Bell' he soon reunited with the band, who then achieved their biggest US hit at the time with 'Lonely Days' in 1970.
During the late 1970s, the Bee Gees departed from their classic pop sound and embraced disco - arguably enjoying the greatest success of their career as a result. They launched a chart comeback with 'Jive Talkin', then produced the multi platinum-selling soundtrack for Saturday Night Fever - spawning major international hits such as 'Night Fever', 'Stayin' Alive', 'You Should Be Dancing' and the often-covered 'How Deep is Your Love'.
Gibb re-established himself as a solo artist again during the 1980s, and also made no secret in interview of his enjoyment of writing music for others. He was credited as a co-writer on material for artists including Celine Dion, Kenny Rogers and Barbra Streisand. Along with the Bee Gees, Gibb also co-wrote Diana Ross's international hit 'Chain Reaction' and Dionne Warwick's 'Heartbreaker'.
The Bee Gees were inducted into the Rock and Roll Hall of Fame in 1997, and received a Brit award that same year recognising their outstanding contribution to the music industry. Honoured with CBEs in a 2004 ceremony at Buckingham Palace, the Bee Gees' worldwide record sales are estimated to be in the region of 220 million.
In his later years, Gibb became known as a prominent supporter of the British armed forces and the Royal British Legion's Poppy Appeal. He served as a judge on the BBC's Fame Academy in 2003, and as a guest mentor on the Australian version of The X Factor two years ago.
In 2009, he collaborated with Sir Tom Jones and Gavin and Stacey actors Ruth Jones and Rob Brydon on a new version of 'Islands in the Stream' for Comic Relief.
Gibb most recently penned his first classical work with son Robin-John to mark the centenary of the RMS Titanic's sinking. The piece, Titanic Requiem, premiered in April this year while Gibb was receiving treatment in hospital. He also took part in a concert at the London Palladium in February in aid of British soldiers returning home from active service in Afghanistan.
Gibb passed away on Sunday, May 20 2012 after a long battle with cancer. His family released a short statement which read: "The family of Robin Gibb, of the Bee Gees, announce with great sadness that Robin passed away today following his long battle with cancer and intestinal surgery. The family have asked that their privacy is respected at this very difficult time."
Gibb is survived by his older brother Barry, his second wife Dwina Murphy Gibb and his children. Gibb's twin brother Maurice died in January 2003 at the age of 53.
