As a young graduate student at the University of Berlin in 1912, Eugen Teuber (1889-1958) was hired to help establish the Anthropoiden Station auf Teneriffa (Tenerife Primate Station) for the Prussian Academy of Sciences, the first field station devoted to behavioral research on primates. As its first director, Teuber played a crucial role in setting up the facilities and acclimating the chimpanzees to their new environment, and he was a co-participant in the first trials of Wolfgang Köhler's famous experiments to evaluate the intelligence of apes. The papers of Eugen Teuber document the founding and earliest years of the Anthropoiden Station auf Teneriffa. A small (0.5 linear feet), tightly focused collection, it contains a series of official documents relating to the establishment of the Station, approximately 20 letters between Teuber and officials in Berlin, including Wilhelm Waldeyer and Max Rothmann, some research notes, and over 100 photographs of the chimpanzees and facilities. The collection includes Teuber's notes on the first trial of Wolfgang Köhler's famous "fruit basket" experiment in December 1913.

Wolfgang Köhler was an internationally recognized leader in experimental psychology. Along with Max Wertheimer and Kurth Koffka, he was a founder of Gestalt psychology, which strongly affected the development of psychology for more then half a century. The Wolfgang Köhler Papers consist of 8 linear feet and are arranged into eight series: correspondence, grant material, lectures, manuscripts, notes, reports of assistants, research notebooks, and photographs and slides. The material relates to Köhler's career as one of the founders of Gestalt Psychology, and work as a experimental researcher.
