Herbert Baxter Adams was an American educator and historian who brought German rigor to the study of history and social science in America. He was a founding member of the American Historical Association, and one of the earliest educators using the seminar for teaching history. With a fresh PhD from the Heidelberg University in Germany, Johns Hopkins University brought Adams in as a teaching fellow in history during their inaugural year. Adams stayed with Johns Hopkins until his health failed.

Thomas Frederick Dixon Jr. was an American Baptist minister, politician, lawyer, lecturer, writer, and filmmaker. Referred to as a "professional racist", Dixon wrote two best-selling novels, The Leopard's Spots: A Romance of the White Man's Burden—1865–1900 (1902) and The Clansman: A Historical Romance of the Ku Klux Klan (1905), that romanticized Southern white supremacy, endorsed the Lost Cause of the Confederacy, opposed equal rights for black people, and glorified the Ku Klux Klan as heroic vigilantes. Film director D. W. Griffith adapted The Clansman for the screen in The Birth of a Nation (1915). The film inspired the creators of the 20th-century rebirth of the Klan.
