Yeats, W(illiam) (B)utler 1865-1939. Irish poet. He was a leader of the Celtic revival and a founder of the Abbey Theatre in Dublin. His early work was romantic and lyrical, as in the poem `The Lake Isle of Innisfree' and plays The Countess Cathleen 1892 and The Land of Heart's Desire 1894. His later books of poetry include The Wild Swans at Coole 1917 and The Winding Stair 1929. He was a senator of the Irish Free State 1922-28. Nobel prize 1923. Yeats was born in Dublin. His early poetry, such as The Wind Among the Reeds 1899, is romantically and exotically lyrical, and he drew on Irish legend for his poetic plays, including Deirdre 1907, but broke through to a new sharply resilient style with Responsibilities 1914. In his personal life there was also a break: the beautiful Maude Gonne, to whom many of his poems had been addressed, refused to marry him, and in 1917 he married Georgie Hyde-Lees, whose work as a medium reinforced his leanings towards mystic symbolism, as in the prose work A Vision 1925 and 1937. His later volumes of verse include The Tower 1928 and Last Poems and Two Plays 1939. His other prose works include Autobiographies 1926, Dramatis Personae 1936, Letters 1954, and My Theologies 1959.
