 In the field of psychology, Stumpf’s name is also associated with the famous case of Clever Hans, which aroused great interest in the early twentieth century, and which represented a significant step in the development of experimental psychology. (H. Baranzke, 2001 W. Prinz, 2006 H. Gundlach, 2006) We know that Stumpf’s assistant, O. Pfungst devoted an entire book to the case of Clever Hans in which he presented the results of the investigation that he and Stumpf conducted. (Stumpf, 1907a, pp. 7–15) Similarly, Stumpf contributed to the foundation of the anthropoid station in Tenerife where Köhler (1925) conducted his well-known research on chimpanzees. Stumpf was also interested in other similar phenomena, such as the study of child prodigies like Pepito Arriola and many others. He founded in 1901 the Society for Child Psychology and contributed two studies on that topic (Stumpf, 1900, 1901)
