Antoni Gaudí i Cornet (Catalan pronunciation: [ənˈtɔni ɣəwˈði]; 25 June 1852 – 10 June 1926) was a Catalan architect from Reus and the best known practitioner of Catalan Modernism. Gaudí’s works reflect an individualized and distinctive style. Most are located in Barcelona, including his magnum opus, the La Sagrada Família.
Gaudí’s work was influenced by his passions in life: architecture, nature, and religion. Gaudí 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 Modernism, 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 molding the details as he conceived them.
