The Swiss artist HR Giger gained worldwide fame with his biomechanical style, especially through his Oscar for the groundbreaking design in the science fiction film "Alien." The book, conceived as a biography, emerged from over two years of collaboration with HR Giger and was intended from the outset to highlight Giger's significance in art and media history, not only for fantastic art but also for the persistent subversion of the demarcations between high and popular culture.
