He married Sophie Mau while at Heidelberg. It was during this period that Wundt offered the first course ever taught in scientific psychology, all the while stressing the use of experimental methods drawn from the natural sciences, emphasizing the physiological relationship of the human brain and the mind. His background in physiology would have a great effect on his approach to the new science of psychology. His lectures on psychology were published as Lectures on the Mind of Humans and Animals in 1863-1864. He was promoted to Assistant Professor of Physiology at Heidelberg in 1864.[10] Weber (1795–1878) and Fechner (1801–1887), who worked at Leipzig, inspired Wundt's interest in neuropsychology.
