Willa Cather, in full Wilella Sibert Cather, (born December 7, 1873, near Winchester, Virginia, U.S.--died April 24, 1947, New York City, New York), American novelist noted for her portrayals of the settlers and frontier life on the American plains.
... Cather's first novel, Alexander's Bridge (1912), was a factitious story of cosmopolitan life. Under the influence of Sarah Orne Jewett's regionalism, however, she turned to her familiar Nebraska material. With O Pioneers (1913) and My ntonia (1918), which has frequently been adjudged her finest achievement, she found her characteristic themes--the spirit and courage of the frontier she had known in her youth. One of Ours (1922), which won the Pulitzer Prize, and A Lost Lady (1923) mourned the passing of the pioneer spirit.
In her earlier Song of the Lark (1915), as well as in the tales assembled in Youth and the Bright Medusa (1920), including the much-anthologized "Paul's Case," and Lucy Gayheart (1935), Cather reflected the other side of her experience--the struggle of a talent to emerge from the constricting life of the prairies and the stifling effects of small-town life.
A mature statement of both themes can be found in Obscure Destinies (1932). With success and middle age, however, Cather experienced a strong disillusionment, which was reflected in The Professor's House (1925) and her essays Not Under Forty (1936).
Her solution was to write of the pioneer spirit of another age, that of the French Catholic missionaries in the Southwest in Death Comes for the Archbishop (1927) and of the French Canadians at Quebec in Shadows on the Rock (1931). For the setting of her last novel, Sapphira and the Slave Girl (1940), she used the Virginia of her ancestors and her childhood. ... (britannica.com)
