STORM THORGERSON, whose album cover artwork includes Pink Floyd's The Dark Side of the Moon, has died aged 69, the band's management has confirmed.

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

He designed the cover showing a prism spreading a spectrum of colour for The Dark Side Of The Moon.

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

His family released a statement saying he died peacefully on Thursday surrounded by family and friends.

"He had been ill for some time with cancer though he had made a remarkable recovery from his stroke in 2003," it said.

Pink Floyd guitarist and vocalist Dave Gilmour released a statement in which he said the artworks Thorgerson created for the band had been "an inseparable part of our work".

He said: "We first met in our early teens. We would gather at Sheep's Green, a spot by the river in Cambridge and Storm would always be there holding forth, making the most noise, bursting with ideas and enthusiasm. Nothing has ever really changed.

"He has been a constant force in my life, both at work and in private, a shoulder to cry on and a great friend. I will miss him."

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 the prism spreading a spectrum of colour across The Dark Side Of The Moon.
