The Casa Vicens by Antoni Gaudí, under the lens of David Cardelús

Antoni Gaudí i Cornet, (25 June 1852 – 10 June 1926)  was born in 1852 in Riudoms or Reus, to the coppersmith Francesc Gaudí i Serra (1813–1906) and Antònia Cornet i Bertran (1819–1876). He was the youngest of five children, of whom three survived to adulthood: Rosa (1844–1879), Francesc (1851–1876) and Antoni. Gaudí's family originated in the Auvergne region in southern France. One of his ancestors, Joan Gaudí, a hawker, moved to Catalonia in the 17th century; possible origins of Gaudí's family name include Gaudy or Gaudin.

Gaudí's work was influenced by his passions in life: architecture, nature, and religion. He considered every detail of his creations and integrated into his architecture such crafts as ceramics, stained glass, wrought ironwork forging and carpentry. He also introduced new techniques in the treatment of materials, such as trencadís which used waste ceramic pieces.

Under the influence of neo-Gothic art and Oriental techniques, Gaudí became part of the Modernista movement which was reaching its peak in the late 19th and early 20th centuries. His work transcended mainstream Modernisme, culminating in an organic style inspired by natural forms. Gaudí rarely drew detailed plans of his works, instead preferring to create them as three-dimensional scale models and moulding the details as he conceived them. Gaudí's work enjoys global popularity and continuing admiration and study by architects. His masterpiece, the still-incomplete Sagrada Família, is the most-visited monument in Spain.

On 7 June 1926, Gaudí was taking his daily walk to the Sant Felip Neri church for his habitual prayer and confession. While walking along the Gran Via de les Corts Catalanes between Girona and Bailén streets, he was struck by a passing tram and lost consciousness. Assumed to be a beggar because of his lack of identity documents and shabby clothing, the unconscious Gaudí did not receive immediate aid. Eventually some passers-by transported him in a taxi to the Santa Creu Hospital, where he received rudimentary care. By the time that the chaplain of the Sagrada Família, Mosén Gil Parés, recognised him on the following day, Gaudí's condition had deteriorated too severely to benefit from additional treatment. Gaudí died on 10 June 1926 at the age of 73 and was buried two days later.
