Chladni was a physicist whose work focused on experimental acoustics. He invented the “Chladni figure” and various instruments. Until his death, he continued to travel and present his inventions and findings to a wide audience.
Franz Max Osswald, born in Winterthur, graduated as a mechanical engineer in 1905 at the Swiss Federal Institute of Technology (E.T.H.). In 1924, he installed a laboratory for applied acoustics at E.T.H. After completing his habilitation in 1928, he served as the first acoustician at a polytechnic, teaching as a "Privatdozent." Osswald described his discipline as an indispensable complement to architecture, technology, and hygiene.
Colladon was an important physicist working in Switzerland and France. His experiments on the compression of air and liquids, the speed of sound in acoustic signals, and atmospheric electricity brought him academic success and made him a sought-after consulting engineer for gas factories and tunnel construction.
