German physiologist and speech scientist

Ludimar Hermann (October 31, &#; June 5, ) was a German physiologist and speech scientist who used the Edisonphonograph to test theories of vowel production, particularly those of Robert Willis and Charles Wheatstone.

He coined the word formant, a term of importance in modern acoustic phonetics. The Hermann grid is named after him; he was the first to report the illusion in scientific literature.

Physiology research

Hermann was born in Berlin. In addition to his work in phonetics, he was influential as a physiologist. He opposed the notion, propounded by Emil du Bois-Reymond, that muscles contained an ordered series of "electromotive molecules" in favor of a theory of chemical activity.^[1] Hermann showed that the entire surface of an uninjured muscle was electrically equipotential.

His discoveries in this field were instrumental to the modern use of the electrocardiograph as a diagnostic tool.^[2&#
