Short answers, pulled from the story.
Salvador Dalí was born on the 11th of May 1904, eight months after his older brother died of gastroenteritis on the 1st of August 1903. The family named the newborn Salvador to honor the dead child, creating a psychological burden that haunted the artist for the rest of his life.
Salvador Dalí developed a technique called the paranoiac-critical method to access the subconscious and create hallucinatory images with the precision of a classical master. This process involved inducing a self-induced paranoid state to interpret reality in multiple ways simultaneously, resulting in double images and optical illusions.
Salvador Dalí was expelled from the Surrealist group in 1939 because André Breton claimed he had espoused race war and that his paranoiac-critical method was a repudiation of Surrealist automatism. The conflict intensified when Dalí publicly supported the Francoist regime after the Spanish Civil War and refused to denounce fascism.
Nuclear Mysticism is a style Salvador Dalí developed after returning to Spain in 1948 that fused classical art, Catholic mysticism, and recent scientific developments. He sought to synthesize Christian iconography with images of material disintegration inspired by nuclear physics and incorporated DNA strands and atomic particles into his paintings from the mid-1950s.
Salvador Dalí died of cardiac arrest on the 23rd of January 1989 and is buried in the crypt below the stage of his Theatre-Museum. The museum is located in his hometown of Figueres and opened in 1974 as the centerpiece of his later life.
