 She received the Pulitzer Prize for Poetry in 1923, the third woman to win the award for poetry, and was also known for her feminist activism.

 The poet Richard Wilbur asserted, "She wrote some of the best sonnets of the century."
John Butler Yeats (16 March 1839 – 3 February 1922) was an Irish artist and the father of William Butler Yeats, Lily Yeats, Elizabeth Corbett "Lolly" Yeats and Jack B. Yeats.
 He is probably best known for his portrait of the young William Butler Yeats which is one of a number of his portraits of Irishmen and women in the Yeats museum in the National Gallery of Ireland.
 His portrait of John O'Leary (1904) is considered his masterpiece (Raymond Keaveney 2002).
The Richard Wilbur Award is named in honor of the American poet Richard Wilbur and was established at the University of Evansville under the direction of William Baer.

Richard Purdy Wilbur (born March 1, 1921) is an American poet and literary translator.
 He is considered by many to be one of the greatest of the 20th century.
 Working primarily in traditional forms, his work is marked by its wit, charm, and gentlemanly elegance.
 Wilbur was appointed the second Poet Laureate Consultant in Poetry to the Library of Congress in 1987, and twice received the Pulitzer Prize for Poetry, in 1957 and again in 1989.
Candide is an operetta with music composed by Leonard Bernstein, based on the 1759 novella of the same name by Voltaire.
 The operetta was first performed in 1956 with a libretto by Lillian Hellman; but since 1974 it has been generally performed with a book by Hugh Wheeler which is more faithful to Voltaire's novel.
 The primary lyricist was the poet Richard Wilbur.
 Other contributors to the text were John Latouche, Dorothy Parker, Lillian Hellman, Stephen Sondheim, John Mauceri, John Wells, and Bernstein himself.
 Maurice Peress and Hershy Kay contributed orchestrations.
 Although unsuccessful at its premiere, "Candide" has now overcome the unenthusiastic reaction of early audiences and critics and achieved enormous popularity.
 It is very popular among major music schools as a student show because of the quality of its music and the opportunities it offers to student singers.
William Butler Yeats ( ; 13 June 186528 January 1939) was an Irish poet and one of the foremost figures of 20th century literature.

 Yeats was a driving force behind the Irish Literary Revival along with Lady Gregory, Edward Martyn and others.

A Sense of Wonder is the fifteenth studio album by Northern Irish singer-songwriter Van Morrison released in 1984.
 On first release, original pressings had to be recalled when the W. B. Yeats estate refused to allow Morrison's musical version of the poem "Crazy Jane on God" to be included, as they believed his poems should only be set to classical music.
 Morrison substituted "If You Only Knew" for the Yeats' recording.
 (Later, perhaps due to Morrison's efforts, Yeats poems would be put to rock settings on a whole album).
