Joseph Guichard Duverney

Shortly afterwards, he relocated to Paris where he was active in the circle of Abbé Pierre Michon Bourdelot where he came into contact with Claude Perrault.

He began to dissect and compare a wide range of animals including fish with Philippe de La Hire.

Some of his students included Pierre Dionis (1643-1718), Jacques-Bénigne Winslow (1669-1760), Jean-Baptiste Sénac (1693-1770) and François-Joseph Hunauld (1701-1742).

[8] Duverney's theory of hearing (which he conceived with the help of physicist Edme Mariotte)[9] was fundamentally similar to what physiologist Hermann von Helmholtz (1821–1894) later proposed in the mid-19th century, except that he thought that high frequency would resonate near the apex of the cochlea, and low frequencies near the base (Domenico Cotugno had to turn this around in 1760).

He realized the importance of the Eustachian tube and its role in adjusting air pressure in the tympanic cavity.
