His landmark 1962 novel, The Man in the High Castle, imagined an alternate history in which the Axis powers won World War II, earning him the Hugo Award. His 1968 masterpiece, Do Androids Dream of Electric Sheep?—the basis for the film Blade Runner—profoundly questioned what it means to be human. Other celebrated works include Ubik (1969), Flow My Tears, the Policeman Said (1974), and A Scanner Darkly (1977), a semi-autobiographical novel reflecting his struggles with drug addiction. His later VALIS trilogy blended Gnostic mysticism with autobiographical elements.
Though largely unrecognized during his lifetime, Dick's reputation soared after his death, with numerous adaptations such as Minority Report, Total Recall, and A Scanner Darkly. Today, he is regarded as one of the most influential and original figures in science fiction literature.
