Gerhard Sessler
Gerhard Martin Sessler (born February 15, 1931 in Rosenfeld , Baden-Württemberg ) is professor for electroacoustics at the TU Darmstadt , as well as the inventor of the electret microphone and the silicon microphone .
Life
Sessler was born on February 15, 1931 as the son of the veterinarian Dr. Martin Sessler was born in Rosenfeld. He studied physics in Freiburg, Munich and Göttingen, where he obtained his diploma in 1957. In 1959 Sessler received his doctorate in Göttingen on the subject of sound propagation in partially dissociated, gaseous nitrous oxide. Shortly after completing his doctorate, he moved to the USA and did research at Bell Labs , where he was head of the Acoustics Research Department from 1967 to 1975. Together with his colleague James E. West , he invented the foil electret microphone in 1962, for which a patent was granted in 1964. Electret microphones now make up 90% of all microphones produced and can be found in camcorders and cell phones, for example. In 1975, Sessler became professor for electroacoustics in the electrical engineering and information technology department of the TU Darmstadt . It was there that he and his colleagues developed the silicon microphone in the 1980s. Even after his retirement in 1999, he heads the electroacoustics research group in the electrical engineering and information technology department at TU Darmstadt.
Sessler was Dean of the Faculty of Electrical Engineering and Information Technology in 1976 and 1977 and 1989–1990.
Sessler is a member of the German Academy of Science and Engineering (Acatech) and the Heidelberg Academy of Sciences .
He is widowed and has three children.
