A childhood friend of the founding members of the band, he became their designer-in-chief, fashioning a string of eye-catching creations.

Most-famously he designed the prism spreading a spectrum of colour across The Dark Side Of The Moon.

His credits also include albums by Led Zeppelin, Peter Gabriel and Muse.

A statement on the Pink Floyd.com official site said: "We are saddened by the news that long-time Pink Floyd graphic genius, friend and collaborator, Storm Thorgerson, has died.

"Our thoughts are with his family and many friends."

Thorgerson began his career with UK design group Hipgnosis, founded in the late 1960s and his distinctive style made him one of the industry's most recognisable artists.

There was the mournful-looking cow on the front of Atom Heart Mother, the burning businessman on the sleeve of Wish You Were Here, the giant pig flying over Battersea Power Station and - most famously of all - the prism spreading a spectrum of colour across The Dark Side Of The Moon.

He told the BBC in 2009: "It's a nice but simple idea. Refracting light through a prism is a common feature in nature, as in a rainbow. I would like to claim it, but unfortunately it's not mine!"

The idea was sparked by Pink Floyd's keyboard player, the late Richard Wright, he explained.

"He said, somewhat provocatively, 'Let's not have one of your photos, we've had your photos before. Can't we have a change? A cool graphic - something smart, tidy, elegant.
