 Wilhelm Windelband (1848–1915) was a German neo-Kantian philosopher. He is considered the founding father of the Baden (or Southwest) school of Neo-Kantianism. The Baden school included his student and successor at Heidelberg, Heinrich Rickert (1863–1936), and Rickert’s student Emil Lask (1875–1915) as its core members. Alongside his contemporary Hermann Cohen (1842–1918)—the founder of the Marburg school of Neo-Kantianism—Windelband is a central proponent of the anti-psychologistic interpretation of Kant that became dominant in German academic philosophy from the 1880s onwards, and that constituted the backbone of “orthodox” neo-Kantianism in the late nineteenth century.
