Claude Gernade Bowers (November 20, 1878 in Westfield, Indiana – January 21, 1958 in New York City) was a newspaper columnist and editor, author of best-selling books on American history, Democratic Party politician, and President Franklin D. Roosevelt's ambassador to Spain (1933–1939) and Chile (1939–1953). His histories of the Democratic Party in its formative years from the 1790s to the 1830s helped shape the party's self-image as a powerful force against monopoly and privilege. Bowers was a sharp critic of Republicans and their Reconstruction policies for African American voting rights and civil rights.
