Maurice Duruflé
Maurice Duruflé  (born Louviers, 11 January 1902;  died Louveciennes,   16 June 1986) was a French composer and organist.  He was very self-critical and destroyed any of his compositions that he thought were not really good.  This is why we now only have a small number of his works.  He wrote choral music and music for the organ.  His most famous work is his Requiem.
