Storm Thorgerson, the British visual artist known for his iconic album covers, has died after a battle with cancer, the BBC reports. He was 69.

Thorgerson's most famous work was for Pink Floyd, with whom he collaborated for decades. He designed the legendary covers of The Dark Side of the Moon (pictured above), Wish You Were Here, and more. He also designed the art for Led Zeppelin's Houses of the Holy and In Through the Out Door, as well as albums by Peter Gabriel, Muse, the Mars Volta, Ween, and countless others. He was a member of the pioneering design collective Hipgnosis.

Thorgerson was a longtime friend of the members of Pink Floyd. In a statement on his website, David Gilmour said, "He has been a constant force in my life, both at work and in private, a shoulder to cry on and a great friend. The artworks that he created for Pink Floyd from 1968 to the present day have been an inseparable part of our work. I will miss him."

Thorgerson's death comes at a time when fans are paying especially close attention to his most famous work-- last month marked the 40th anniversary of The Dark Side of the Moon, which inspired many tributes and related coverage.
