British musician George Rogers Waters was one of the founders of Pink Floyd. He formed the group in 1965 and kept up the momentum, even as frontman and key songwriter Syd Barrett left the group in 1968 due to mental health and drug issues.

Studying architecture in London, Waters got to know Nick Mason and Rick Wright in 1964. They founded the cover band Sigma 6, later changing the name to The Tea Set. In 1965, Syd Barrett changed it yet again to the Pink Floyd Sound - named after blues musicians Pink Anderson and Floyd Council. This photo captures Waters (22), Mason (22), Barrett (21) and Wright (21) in March 1967 in London.

While Barrett had defined the band's early psychedelic sound, his successor Dave Gilmour - with Rogers Waters - rapidly shifted the style in a more progressive direction, influenced by blues, jazz, classical, and avant-garde music. By 1973, Waters (pictured) had become the band's central figure, contributing all lyrics until his eventual departure in 1985.

The band's catapult to stardom came with the concept album "The Dark Side of the Moon" in 1973. While Rogers conceived the idea, all four members contributed compositions and it remains the most successful album from the group. From 2006-2008 Waters went on to tour the album as a solo artist. The album's laser prism artwork has become truly iconic.

The concept for the stage show of "The Wall" from 1979 draws on Waters' own life. It tells of the loneliness of a rock singer, struggling to deal with the death of his father. The work is largely biographical as Waters' own father died in World War II. The bestselling double album of all time, it's also widely considered the band's last great work.

While working on "The Wall," the first major cracks began to appear between band members. Richard Wright would leave the band after making of album, leaving Roger Waters with the rights to the music. From 2010-2013 Waters toured the record around the world once again. This picture was captured at Berlin's Olympia Stadium in September 2013.

But the most famed concert would take place on July 21, 1990, after the fall of the Berlin Wall, in the "no-man's-land" between Potsdamer Platz and the Brandenburg Gate. Historically, it is the only concert to ever have taken place in two states simultaneously. Waters was joined by Van Morrison, Bryan Adams, Cyndi Lauper, Sinéad O’Connor, and Scorpions. All artists waived their fees.

The success of "The Wall" couldn't reverse internal conflicts within the group - and the situation quickly deteriorated. The dispute between Waters and Gilmour escalated and in 1985 Waters declared the band finished. However, Gilmour, Mason and Wright would continue to tour and write music as Pink Floyd.

Meanwhile, tensions between the existing members have died down. In 2010, Waters and Gilmour appeared together to show their support for the Palestinians in the West Bank - with Waters shown here writing the words "no thought control" on the border with Bethlehem. In 2011, Gilmour and Mason both made appearances in Waters' world tour - although there are few signs of a genuine Pink Floyd reunion.
