 Kuhn’s Structure of Scientific Revolutions (1962/1970a) was the original manifesto of historicist philosophy of science and remains the primary reference point. His work thus provides the most useful platform for recounting early historicist efforts—and the difficulties they faced. We shall then take a briefer look at other major contributors. Kuhn had been anticipated in quite diverse ways by Kant, Hegel, William Whewell, Émile Meyerson, Ernst Cassirer, Alexandre Koyré, Philipp Frank, Gaston Bachelard, Ludwik Fleck, Hans Reichenbach, Rudolf Carnap, W.V. Quine, Michael Polanyi, Hesse, Toulmin, and Hanson and was immediately followed by Lakatos, Feyerabend, Shapere, Laudan, and others (see the entry on  Thomas Kuhn;  also Hoyningen-Huene [1989] 1993 and Rheinberger [2007] 2010b).
