Document 5: Richard Wright (author): Richard Nathaniel Wright (September 4, 1908 – November 28, 1960) was an American author of sometimes controversial novels, short stories, poems, and non-fiction. Much of his literature concerns racial themes, especially related to the plight of African Americans during the late 19th to mid-20th centuries, who suffered discrimination and violence in the South and the North. Literary critics believe his work helped change race relations in the United States in the mid-20th century.
Document 6: James Baldwin: James Arthur "Jimmy" Baldwin (August 2, 1924 – December 1, 1987) was an American writer and social critic. His essays, as collected in "Notes of a Native Son" (1955), explore palpable yet unspoken intricacies of racial, sexual, and class distinctions in Western societies, most notably in mid-20th-century America. Some of Baldwin's essays are book-length, for instance "The Fire Next Time" (1963), "No Name in the Street" (1972), and "The Devil Finds Work" (1976). An unfinished manuscript, "Remember This House", was expanded upon and adapted for cinema as the Academy Award-nominated documentary film "I Am Not Your Negro".
Document 7: Ralph Ellison: Ralph Waldo Ellison (March 1, 1913 – April 16, 1994) was an American novelist, literary critic, and scholar. Ellison is best known for his novel "Invisible Man", which won the National Book Award in 1953. He also wrote "Shadow and Act" (1964), a collection of political, social and critical essays, and "Going to the Territory" (1986). For "The New York Times", the best of these essays in addition to the novel put him "among the gods of America's literary Parnassus." A posthumous novel, "Juneteenth", was published after being assembled from voluminous notes he left after his death.
Document 8: Graham Greene: Henry Graham Greene (2 October 1904 – 3 April 1991), better known by his pen name Graham Greene, was an English novelist regarded by many as one of the great writers of the 20th century. Combining literary acclaim with widespread popularity, Greene acquired a reputation early in his lifetime as a major writer, both of serious Catholic novels, and of thrillers (or "entertainments" as he termed them). He was shortlisted, in 1966 and 1967, for the Nobel Prize for Literature. Through 67 years of writings, which included over 25 novels, he explored the ambivalent moral and political issues of the modern world, often through a Catholic perspective.
Document 9: African-American literature: African-American literature is the body of literature produced in the United States by writers of African descent. It begins with the works of such late 18th-century writers as Phillis Wheatley. Before the high point of slave narratives, African-American literature was dominated by autobiographical spiritual narratives. The genre known as slave narratives in the 19th century were accounts by people who had generally escaped from slavery, about their journeys to freedom and ways they claimed their lives. The Harlem Renaissance of the 1920s was a great period of flowering in literature and the arts, influenced both by writers who came North in the Great Migration and those who were immigrants from Jamaica and other Caribbean islands. African-American writers have been recognized by the highest awards, including the Nobel Prize to Toni Morrison. Among the themes and issues explored in this literature are the role of African Americans within the larger American society, African-American culture, racism, slavery, and social equality. African-American writing has tended to incorporate oral forms, such as spirituals, sermons, gospel music, blues, or rap.
Document 10: Chicago Black Renaissance: The Chicago Black Renaissance (also known as the Black Chicago Renaissance) was a creative movement that blossomed out of the Chicago Black Belt on the city's South Side and spanned the 1930s and 1940s before a transformation in art and culture in the mid-1950s through the turn of the century. The movement included such famous African-American writers as Richard Wright, Margaret Walker, Gwendolyn Brooks, Arna Bontemps, and Lorraine Hansberry, as well as musicians Thomas A. Dorsey, Louis Armstrong, and Earl Hines. During the Great Migration, which brought tens of thousands of African-Americans to Chicago's South Side, African-American writers, artists, and community leaders began promoting racial pride and a new black consciousness, similar to that of the Harlem Renaissance in New York City. Unlike the Harlem Renaissance, the Chicago Black Renaissance did not receive the same amount of publicity on a national setting. This was due to several factors, including the lower profile participants in the movement, the lack of wealthy patrons investing in the movement, and a geographical distance from New York as a publishing center.
Document 11: John O'Hara: John Henry O'Hara (January 31, 1905 – April 11, 1970) was an American writer, best remembered as a keen observer of social status and manners in early to mid 20th century America and pre-eminent among his contemporaries at depicting social realism. He first earned a reputation for short stories and later became a best-selling novelist before the age of 30 with "Appointment in Samarra" and "BUtterfield 8".
Document 12: Uncle Tom's Children: Uncle Tom's Children is a collection of novellas and the first book published by African-American author Richard Wright, who went on to write "Native Son" (1940), "Black Boy" (1945), and "The Outsider" (1953). When it was first published in 1938, "Uncle Tom's Children" included only four novellas: "Big Boy Leaves Home," "Down by the Riverside," "Long Black Song," and "Fire and Cloud." "The Ethics of Living Jim Crow" and "Bright and Morning Star," which are now the first and final pieces, respectively, were added when the book was republished in 1940. The book's title is derived from Harriet Beecher Stowe's "Uncle Tom's Cabin," an anti-slavery novel published in 1852.
Document 13: Henry Green: Henry Green was the pen name of Henry Vincent Yorke (29 October 1905 – 13 December 1973), an English author best remembered for the novels "Party Going" and "Loving".
Document 14: The Outsider (Wright novel): The Outsider is a novel by American author Richard Wright, first published in 1953. "The Outsider" is Richard Wright's second installment in a story of epic proportions, a complex master narrative to show American racism in raw and ugly terms. The kind of racism that Wright knew and experienced, a racism from which most black people of his own time could not escape, remained the central element in his fiction. "The Outsider" appeared during the height of McCarthyism in the United States and the advent of the Cold War in Europe, two events which had a significant bearing on its initial reception.
Document 15: Henry Petowe: Henry Petowe (1575/6–1636?) was a minor Elizabethan poet, best known today, perhaps, for "The Second Part of "Hero and Leander", Containing their Further Fortunes," his sequel to Christopher Marlowe's "Hero and Leander".
