About César Cui
César Antonovich Cui (Russian: Цезарь Антонович Кюи, romanized: Tsezar Antonovich Kyui; IPA: [ˈt͡sjezərʲ ɐnˈtonəvʲɪt͡ɕ kʲʊˈi]; French: Cesarius Benjaminus Cui; 18 January [O.S. 6 January] 1835 – 26 March 1918) was a Russian composer and music critic, member of the Belyayev circle and The Five – a group of composers gathered by the idea of creating a specifically Russian type of music. As an officer of the Imperial Russian Army, he rose to the rank of engineer-general (equivalent to full general), taught fortifications in Russian military academies and wrote a number of monographs on the subject. Throughout his rather long and active musical life, Cui won many accolades. Shortly after the staging of Le flibustier in Paris, Cui was elected as a correspondent member of the Académie Française and was awarded the cross of the Légion d'honneur.
