Frédéric Justin Collet

Frédéric Justin Collet (April 28, 1870 - 1966) was a French pathologist and otolaryngologist. In 1894 he earned his doctorate from the University of Lyon. Later he became a professor of pathology in Lyon, and in 1927 a professor of otolaryngology.

Collet is remembered for providing a description of a disorder he called glossolaryngoscapulopharyngeal hemiplegia, which was later to be named Collet's syndrome. This disorder is caused by a lesion of cranial nerves IX, X, XI, and XII, and results in the paralysis of the tongue, vocal cords, palate, trapezius muscle, et al. Sometimes this condition is referred to as the Collet-Sicard syndrome, which was named in conjunction with Jean-Athanase Sicard, who also provided a description of the disorder independent of Collet.

In 1910, along with André Chantemesse (1851-1919) and Antonin Poncet (1849-1913), he founded the Bibliothèque de la Tuberculose, which was a collection of monographs regarding tuberculosis. In his treatise L'odorat et ses troubles, Collet discusses the correlation between the sense of smell and feminine sexual arousal.
