Although Wilhelm Wundt (1832–1920) was not the first to address psychological questions with scientific means, he was the first to establish a scientific laboratory devoted specifically to psychology. This was done in 1879 at the University of Leipzig. Ernst Weber (1795–1878), Hermann Helmholtz (1821–1894), and Gustav Fechner (1801–1887) had all made important contributions to our understanding of sensation and perception prior to this, but none of them considered himself a psychologist per se. Wundt, in contrast, was specifically focused upon establishing psychology as a science.
