from Zurich. Located in the Konvikt building, many of Wundt's demonstrations took place in this laboratory due to the inconvenience of transporting his equipment between the lab and his classroom. Wundt arranged for the construction of suitable instruments and collected many pieces of equipment such as tachistoscopes, chronoscopes, pendulums, electrical devices, timers, and sensory mapping devices, and was known to assign an instrument to various graduate students with the task of developing uses for future research in experimentation. Between 1885 and 1909, there were 15 assistants. In 1879, Wundt began conducting experiments that were not part of his course work, and he claimed that these independent experiments solidified his lab's legitimacy as a formal laboratory of psychology, though the university did not officially recognize the building as part of the campus until 1883. The laboratory grew and encompassing a total of eleven rooms, the Psychological Institute, as it became known, eventually moved to a new building that Wundt had designed specifically for psychological research. Wundt's teaching in the Institute for Experimental Psychology The list of Wundt's lectures during the winter terms of 1875–1879 shows a wide-ranging programme, 6 days a week, on average 2 hours daily, e.g. in the winter term of 1875: Psychology of language, Anthropology, Logic and Epistemology; and during the subsequent summer term: Psychology, Brain and Nerves, as well as Physiology. Cosmology, Historical and General Philosophy were included in the following terms. Wundt's doctoral students Wundt was responsible for an extraordinary number of doctoral dissertations between 1875 and 1919: 184 students included 70 foreigners (of which 23 were from Russia, Poland and other east-European countries and 18 were from America). Several of Wundt's students became eminent psychologists in their own right. They include: the Germans Oswald Külpe (a professor at the University of Würzburg), Ernst Meumann (a professor in Leipzig and Hamburg and pioneer in pedagogical psychology), Hugo Münsterberg a professor in Freiburg and at Harvard University, a pioneer in applied psychology), Willy Hellpach (in Germany known for cultural psychology). The Americans listed include James McKeen Cattell (the first professor of psychology in the United States), Granville Stanley Hall (the father of the child psychology movement and adolescent developmental theorist, head of Clark University), Charles Hubbard Judd (Director of the School of Education at the University of Chicago), Walter Dill Scott (who contributed to the development of industrial psychology and taught at Harvard University), Edward Bradford Titchener,
