Jehan Ariste Alain (born February 3, 1911 in Saint-Germain-en-Laye, † 20 June 1940 in Petit-Puy Saumur) was a French organist and composer. From 1927 to 1939, he studied at the Conservatoire National Superieur in Paris, where he received first prize in harmony, fugue, counterpoint, organ and improvisation. In 1935, Alain was appointed organist at St. Nicolas de Maisons-Lafitte in Paris, where he would work for four years. After he was called up for military service in 1939, Jehan Alain fell in a skirmish at Saumur on June 20, 1940. His compositional work was not only influenced by the musical language of Claude Debussy and Olivier Messiaen, but also through its inclusion of Far Eastern and old music styles. He became one of the most interesting musicians in France during the first half of the 20th century. The work directory Alain (numbered, similar op.) Includes more than 140 compositions. He wrote music for piano and orchestra, and vocal and chamber music. However, he owes most of his fame to his organ works.
