- Hans Heinrich Eggebrecht
(b Dresden, June 18, 1909; d Bad Reichenhall, June 13, 1997). German acoustician. After attending the Technische Hochschule in Dresden (1928–9), he studied at the universities of Kiel, Tübingen and Berlin (where he was a pupil of Biehle). His work with M. Grützmacher and Gurlitt during this period stimulated his later research. In 1935 he received a doctorate in physics at the University of Berlin with a dissertation on reed pipes. From 1936 to 1945 he worked first in the State Institute of Physics and Technology in Berlin-Charlottenburg and later was independently employed in the physics department of Tübingen University. In 1952 he began work in the Federal Institute of Physics and Technology in Brunswick, becoming administrative adviser in 1953, chief adviser and head of the acoustics laboratory in 1956, and in 1968 professor and director of the institute. He retired in 1971.
Lottermoser conducted extensive research into the acoustics of instruments, especially the organ and violin, and into the physiology of hearing them. Through his articles on differing architectural styles in churches he contributed to the study and improvement of spatial acoustics....
