Person

Adriaan Daniël Fokker was a prominent Dutch theoretical physicist. He is known in theoretical physics for the Fokker-Planck equation and his work on the theory of relativity. In the years around 1930, however, Fokker also became interested in room acoustics and the tuning of musical instruments. He designed several sound reflectors, which amplify the sound reaching the audience, especially in churches, but his work on musical instrument tuning is what made him more widely known.

After travels in France and England and a voluntary year in the military, he started teaching at secondary schools in Berlin in 1905. Focusing more and more on phonetics and prosody, Doegen published teaching materials for language learning and pronunciation.

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.
