Roderick Aldon Walcott, OBE (23 January 19306 March 2000), was a St Lucian playwright, screenwriter, painter, theatre director, costume and set designer, lyricist and literary editor.
 As a dramatist he "has been recognised as one of the most committed figures in the effort to develop a distinctive Caribbean theatre in the region".
 He was the twin brother of Nobel laureate Derek Walcott.
Omeros is an epic poem by Caribbean writer Derek Walcott, first published in 1990.
 The work is divided into seven "books" containing a total of sixty-four chapters.
 Many critics view "Omeros" as Walcott's "major achievement."
 Soon after its publication in 1990, it received praise from publications like "The Washington Post" and "The New York Times Book Review", the latter of which chose the book as one of its "Best Books of 1990" and called it "one of Mr. Walcott's finest poetic works."
 The book also won the WH Smith Literary Award in 1991.
 In 1992, Walcott was also awarded the Nobel Prize for Literature, and the Nobel committee member who presented the award, Professor Kjell Espmark, singled out Walcott's most recent achievement at the time, "Omeros", recognizing the book as a "major work".
 Walcott painted the cover for the book, which depicts some of his main characters at sea together in a boat.
 In 2004, the critic Hilton Als of "The New Yorker" called the book "Walcott's masterpiece" and characterized the poem as "the perfect marriage of Walcott’s classicism and his nativism".
This is a list of Danish Nobel laureates.
 Since the Nobel Prize was established per the will of Swedish inventor Alfred Nobel in 1895, 12 of the prize winners have been from Denmark.
 The first Danish Nobel laureate was Niels Ryberg Finsen, who won a Nobel Prize for medicine in 1903 for his work in using light therapy to treat diseases.
 The most recent Danish Nobel Prize winner was Jens Skou who won the prize in chemistry for his discovery over the enzyme, Na+/K+-ATPase in 1997.
 To date, of the 13 Nobel Prizes won by Danish people, 5 have been for medicine, 3 have been for physics, 3 have been for literature, 1 has been for chemistry and one has been for peace.
Trinidad Theatre Workshop was founded in 1959, by 1992 Nobel Laureate Derek Walcott, with his twin brother Roderick Walcott and performers including Beryl McBurnie, Errol Jones and Stanley Marshall, and started at the Little Carib Theatre before moving to other venues in Port of Spain.
 Derek Walcott was the founding director, from 1959 to 1971.
 In its inaugural season, the Workshop presented "The Blacks" by Jean Genet, Eric Roach's "Belle Fanto", and "The Road" by Wole Soyinka.
 The company continues to produce works by Walcott and others (including such diverse dramatists as Dario Fo, Tennessee Williams, Anton Chekhov, Ntozake Shange, Neil Simon, and Athol Fugard among many others), and in recent years has offered educational programs and community outreach in the region in addition to its production schedule.
Sir Derek Alton Walcott, KCSL, OBE, OCC (23 January 1930 – 17 March 2017) was a Saint Lucian poet and playwright.
 He received the 1992 Nobel Prize in Literature.
 He was Professor of Poetry at the University of Essex from 2010 to 2013.
 His works include the Homeric epic poem "Omeros" (1990), which many critics view "as Walcott's major achievement."
 In addition to winning the Nobel Prize, Walcott received many literary awards over the course of his career, including an Obie Award in 1971 for his play "Dream on Monkey Mountain", a MacArthur Foundation "genius" award, a Royal Society of Literature Award, the Queen's Medal for Poetry, the inaugural OCM Bocas Prize for Caribbean Literature, the 2011 T.

 Her other novels have similar themes and most are set in the deep South.
The Member of the Wedding is a 1946 novel by Southern writer Carson McCullers.
 It took McCullers five years to complete, although she interrupted the work for a few months to write the short novel "The Ballad of the Sad Café".
The Poetry and People International Poetry Prize is an annual international lifetime achievement award given to poets around the world by the poetry magazine Poetry and People and its founder Huang Lihai.
