Deirdre of the Sorrows is a three-act play written by Irish playwright John Millington Synge, first performed at the Abbey Theatre by the Irish National Theatre Society in 1910.
 The play is based on Irish mythology, in particular the myths concerning Deirdre and Conchobar.
 The work was unfinished at the author's death in 1909, but was completed by William Butler Yeats and Synge's fiancée, Molly Allgood.
Jonny Steinberg is a South African writer and scholar.
 He is the author of several books about everyday life in the wake of South Africa’s transition to democracy.
 Two of them, "Midlands" (2002), about the murder of a white South African farmer, and "The Number" (2004), a biography of a prison gangster, won South Africa’s premier non-fiction award, the "Sunday Times" Alan Paton Award.
 In 2013, he was among the inaugural winners of the Windham-Campbell Literature Prizes, awarded by Yale University.
 Steinberg’s books also include "Three-Letter Plague" ("Sizwe’s Test" in the United States), which chronicles a young man’s journey through South Africa’s AIDS pandemic.
 It was a "Washington Post" Book of the Year and was shortlisted for the Wellcome Trust Book Prize, among others.
 Steinberg is also the author of "Thin Blue" (2008), an exploration of the unwritten rules of engagement between South African civilians and police, and "Little Liberia: An African Odyssey in New York" (2011), about the Liberian civil war and its aftermath in an exile community in New York and described as an "extraordinary, stylistically varied mix of reportage, history and biography".
 Steinberg's 2015 book, "A Man of Good Hope", was described as "superb" by "Observer" reviewer Ian Birrell, who wrote: "On the surface, it is simply the biography of a lonely young migrant who dreams of a decent life, hardening his shell and hustling to survive in hostile human environments.
 Yet it is really an epic African saga that chronicles some fundamental modern issues such as crime, human trafficking, migration, poverty and xenophobia, while giving glimpses into the Somali clan system, repression in Ethiopia and lethal racism in townships."
The Playboy of the Western World is a 1962 film version of the 1907 play written by John Millington Synge.
 It was directed and co-written by Brian Desmond Hurst and stars Gary Raymond and Siobhán McKenna.
 Filmed in County Kerry, the film features many of the Abbey Players.
 The film was produced by the Four Provinces company created in 1952 by Hurst and Michael Morris, 3rd Baron Killanin who had previously produced John Ford’s "The Rising of the Moon" and "Gideon's Day".
(William) Denis Johnston (18 June 1901 – 8 August 1984) was an Irish writer.
 Born in Dublin, he wrote mostly plays, but also works of literary criticism, a book-length biographical essay of Jonathan Swift, a memoir and an eccentric work on cosmology and philosophy.
 He also worked as a war correspondent, and as both a radio and television producer for the BBC.
 His first play, "The Old Lady Says "No!""
, helped establish the worldwide reputation of the Dublin Gate Theatre; his second, "The Moon in the Yellow River", has been performed around the globe in numerous productions featuring such actors as Jack Hawkins, Claude Rains and Errol Flynn, although not all in the same production.
 He played a role in the 1935 film version of John Millington Synge's "Riders to the Sea".
Alan Stewart Paton (11 January 1903 – 12 April 1988) was a South African author and anti-apartheid activist.
 His works include the novels "Cry, the Beloved Country" and "Too Late the Phalarope".
Too Late the Phalarope is the second novel of Alan Paton, the South African author who is best known for writing "Cry, the Beloved Country".
 It was published in 1953, and was the last novel he published before "Ah, but Your Land is Beautiful" in 1981.
Ah, But Your Land is Beautiful is the third novel of Alan Paton, the South African author who is best known for writing "Cry, the Beloved Country".
 "Ah, but Your Land is Beautiful" is an anti-apartheid novel, in a similar vein to "Cry, the Beloved Country".
 It is a fictional reworking of Paton's own years working as a political activist and of the experience he gained working as the president of the South African Liberal Party.
Riders to the Sea is a play written by Irish Literary Renaissance playwright John Millington Synge.
 It was first performed on 25 February 1904 at the Molesworth Hall, Dublin, by the Irish National Theater Society.
 A one-act tragedy, the play is set in the Aran Islands, Inishmaan, and like all of Synge's plays it is noted for capturing the poetic dialogue of rural Ireland.
 The plot is based not on the traditional conflict of human wills but on the hopeless struggle of a people against the impersonal but relentless cruelty of the sea.
Edmund John Millington Synge ( ; 16 April 1871 – 24 March 1909) was an Irish playwright, poet, prose writer, travel writer and collector of folklore.
 He was a key figure in the Irish Literary Revival and was one of the co-founders of the Abbey Theatre.
 He is best known for his play "The Playboy of the Western World", which caused riots in Dublin during its opening run at the Abbey Theatre.
Peter Richard Dreyer (born November 15, 1939) is the author of "A Beast in View" (London: André Deutsch), "The Future of Treason" (New York: Ballantine), "A Gardener Touched with Genius: The Life of Luther Burbank" (New York: Coward, McCann & Geoghegan; rev. ed., Berkeley: University of California Press; new, expanded ed., Santa Rosa, CA: Luther Burbank Home & Gardens), and "Martyrs and Fanatics: South Africa and Human Destiny" (New York: Simon & Schuster; London: Secker & Warburg).
 He was born and brought up in South Africa, where he was involved in the anti-apartheid struggle, serving on the Cape Provincial Committee of the Liberal Party, founded and led by Alan Paton, and as secretary of the Western Province Press Association, which published the fortnightly "The Citizen" (not to be confused with the pro-apartheid tabloid of the same name launched in 1976), which introduced the concept of nonracial democracy in South Africa.
 At the time, the Liberal Party was the only unsegregated political party in South Africa.
 The African National Congress (ANC) restricted its membership to black Africans (excluding not only "whites" but "Coloured" and Indian South Africans too), and did not desegregate itself until many years later.
 Dreyer put forward the idea of nonracialism in a pamphlet titled "Against Racial Status and Social Segregation" (Claremont, Cape Town, 1958; now very rare, but to be found in the Bodleian Library at Oxford University and the Hoover Library at Stanford University).
 The Citizen Group also worked to establish nonracial trade unions, resistance to bus apartheid in Cape Town, and a nonracial theater project, which led to a production of Jean Genet's "The Blacks".
 On February 8, 1958, Patrick Duncan launched the Liberal Party fortnightly "Contact", with offices on Parliament Street in Cape Town.
 Dreyer worked closely with Duncan, and in "Contact", 1, no. 15, dated August 23, 1958, he published an article about the newly formed nonracial South African Meat Workers Union under the by-line “Contact Special Correspondent.”
 On the cover of the magazine, Duncan placed the Citizen group slogan “Forward to a South African patriotism based on non-racial democracy”—the first prominent demand for a nonracial answer to apartheid.
