He was and has been criticized as a “mere burrower into archives”; as a dry man without any ideas; as a painter of miniatures rather than of broad portraits; as a conservative by liberals, and insufficiently dogmatic by conservatives; as motivated by the Lutheran religion of his forebears, but also as a scholar set against teleology and mysticism. This was Leopold von Ranke, born in 1795, dying in Berlin in 1886. Over his long life, he not only influenced the historical world by his writings, but by his students, and their students. Through his teaching and his examples, he altered not only the historical profession in Germany, but in the United States as well through the horde of Americans who passed through faculties of history whose members had been trained by Ranke, or by one of his students. He did  not invent the footnote or the insistence upon using primary sources, but arguably more than anyone else established them as part of the apparatus of history as a social science. With me to talk about Leopold von Ranke is Suzanne Marchand, Boyd Professor of European Intellectual History at Louisiana State University. This September, she was elected to the Presidency of the American Historical Association for 2026. This is her fourth appearance on Historically Thinking; she was last with us as part of our continuing series on intellectual humility and historical thinking.
