Karl Vorländer (1860, Marburg - 1928) was a German neo-Kantian philosopher who taught in Solingen. He published various studies and editions of the works of Kant, including studies of the relation between Kantian thought and socialist thought, and of the influence of Kant on the work of Johann Wolfgang Goethe. His 1924 biography of Kant became a classic of Kant scholarship for much of the twentieth century (see Herbert Schnädelbach, Kant. Leipzig: Reclam, 2005, p. 152).
