Erskine Caldwell Erskine Preston Caldwell (December 17, 1903 – April 11, 1987) was an American novelist and short story writer. His writings about poverty, racism and social problems in his native Southern United States in novels such as "Tobacco Road" (1932) and "God's Little Acre" (1933) won him critical acclaim, but also made him controversial among Southerners of the time who felt he was deprecating the people of the region.
