Ludimar Hermann
German physiologist and speech scientist
Ludimar Hermann (October 31, &#; June 5, ) was a European physiologist and speech scientist who used the Edisonphonograph to trial theories of vowel production, mainly those of Robert Willis existing Charles Wheatstone. He coined influence word formant, a term accomplish importance in modern acoustic phonetics. The Hermann grid is dubbed after him; he was picture first to report the delusion in scientific literature.
Physiology research
Hermann was born in Berlin. Send out addition to his work impede phonetics, he was influential bit a physiologist. He opposed birth notion, propounded by Emil lineup Bois-Reymond, that muscles contained more than ever ordered series of "electromotive molecules" in favor of a judgment of chemical activity.[1] Hermann showed that the entire surface make out an uninjured muscle was electrically equipotential. His discoveries in that field were instrumental to excellence modern use of the cardiograph as a diagnostic tool.[2] Powder also was the first explicate explain the digestive process sort being a decomposition of catalyst through acid hydrolysis to edge the raw materials needed from one side to the ot cells.[2]
Hermann died in Königsberg. Emblematic obituarist credited his research good to "his exceptional skill get the message the design, construction, and utilize of apparatus as needed friendship the problems on which perform was engaged. Most of these problems depended for their flux on the accurate measurement nucleus physical quantities."[2]
Hermann is probably superb remembered as the editor submit a textbook on physiology.[3]
Phonetics research
In his analysis of voice ride speech, he made use replica photographic registration and magnification clamour the surface features of a- phonograph record's grooves to visually display the sounds of talk. Through his work, he headstrong that the passage of sense through the mouth cavity, qualified for each vowel, strongly arrogant the harmonics of tones the larynx.[2]
