Günter Tembrock (1918-2011) was the founder of the first German “Research Center for Animal Psychology” in Berlin in 1948 and is considered the most important researcher in the field of behavioural biology in the GDR. Even though he worked on a comprehensive understanding of the fundamentals of animal behaviour, his special interest was in mammals. He conducted his first behavioural studies on a female chimpanzee at the Berlin Zoo, which formed the basis for his book “Grundzüge der Schimpansen-Psychologie” (Fundamentals of Chimpanzee Psychology), published in 1949.
Leo Leroy Beranek was born on September 15, 1914, in Solon, Iowa, and died on October 10, 2016, in Westwood, Massachusetts. Beranek was an acoustics expert and a founder of the company Bolt, Beranek and Newman.
Son of a musician and a voice teacher, Pierre Schaeffer received a Catholic education, practiced theater as a boy scout, and learned to play the cello at the conservatory in Nancy. He chose to pursue engineering, gaining admission to the Polytechnique in 1929, where he continued his work in theater, followed by studies at the Supélec (top-ranked graduate school for electrical engineering).
Cornelis Zwikker was a Dutch physicist and one of the initiators of the Dutch Sound Foundation. After studying chemistry, mathematics, and physics in Amsterdam, he worked with Philips in Eindhoven until 1929, when he was appointed professor of theoretical and applied physics at the Delft University of Technology. Zwikker was responsible for the acoustic design of many buildings, among them the studios of the Dutch broadcasting organization AVRO.
Peter Paul Kellogg was professor of ornithology and biological acoustics at Cornell University. Together with Arthur Allen and Albert Brand, he developed new techniques and instruments for recording animal (particularly bird) vocalizations. As director of the Cornell Library of Natural Sounds in the 1950s, he continued to play a role in consolidating bioacoustics as a new discipline and promoting popular understanding of acoustics in the natural world.
Georg von Békésy was a Hungarian-American biophysicist who worked on physiology of hearing.
After studying chemistry in Bern, in 1923 Békésy was awarded a PhD in physics at the University of Budapest. He entered the service of the Hungarian Post Office, where he worked at the research laboratory on problems of long-distance telephone transmission.
H. J. L. Struycken was a Dutch otolaryngologist, phonetician, and acoustician. After studying medicine in Groningen, in 1893 he started working at the Voorburg psychiatric hospital near Vught, where he attempted to distinguish psychiatric conditions from neurological speech disorders. His interest in phonetics and acoustics took Struycken to France and Germany, to visit clinics and approach instrument makers who could produce tuning forks for him to use in his clinical research.
Hallowell Davis was born on August 31, 1896, in New York City and died on August 22, 1992, in St. Louis, Missouri. He was a physiologist and otolaryngologist, and his research contributed to the development of electroencephalography (EEG). Davis was also a pioneer in the physiology of hearing, the inner ear, and the auditory nerve’s electrical responses.
