Hans Ruedi Giger (/ˈɡiːɡər/ GHEE-gər; German: [ˈɡiːɡɐ]; 5 February 1940 – 12 May 2014) was a Swiss artist best known for his airbrushed images that blended human physiques with machines, an art style known as "biomechanical".

His style has been adapted to many forms of media, including album covers, furniture, tattoos and video games.

[6][7] He is also well known for artwork on several music recording albums including Danzig III: How The Gods Kill by Danzig, Brain Salad Surgery by Emerson, Lake & Palmer, Attahk by Magma, Heartwork by Carcass, To Mega Therion by Celtic Frost, Eparistera Daimones and Melana Chasmata by Triptykon, Deborah Harry's KooKoo, Atomic Playboys by Steve Stevens, and Frankenchrist by the Dead Kennedys.

For most of his career, he worked predominantly in airbrush, creating monochromatic canvasses depicting surreal, nightmarish dreamscapes.

[2] Giger's most distinctive stylistic innovation was that of a representation of human bodies and machines in cold, interconnected relationships, which he described as "biomechanical".

Giger was also influenced by Polish sculptor Stanislaw Szukalski, and by painters Austin Osman Spare and Mati Klarwein,[16] and was a personal friend of Timothy Leary.

Giger created furniture designs, particularly the Harkonnen Capo Chair for a film of the novel Dune that was to be directed by Alejandro Jodorowsky.

At The Limelight in Manhattan, Giger's artwork was licensed to decorate the VIP room, the uppermost chapel of the landmarked church, but it was never intended to be a permanent installation and bore no similarity to the bars in Switzerland.

On the one year anniversary of his death, the Museum of Arts and Design in New York City staged the series The Unseen Cinema of HR Giger in May 2015.

[29] Dark Star: H. R. Giger's World, a biographical documentary by Belinda Sallin, debuted 27 September 2014 in Zurich, Switzerland.
