François-Louis(-Ferdinand) Henry (12 May 1786 – 22 February 1855) was a French baritone, who sang for about 35 years with the Opéra-Comique in Paris, where he created numerous leading roles. His stage name was Henri (or Henry). He has also been referred to as Henry Deshaynes.
He was born in Versailles with the family name of Deshayes. Relatively little is known about his life, and during his career at the Opéra-Comique he was only identified as Henry or Henri. However, it is as good as certain that he is identical with François-Louis Henry, who attended, and later taught at, the Conservatoire de Paris.
Henry first attended the conservatory as a supernumerary, beginning on 13 May 1803. He became a coach (répétiteur) without pay on 23 May 1808 and professor of singing preparation (préparation au chant) on 1 July, again without pay. He was a student of Charles Simon Catel, a professor of harmony, and won a second prize in harmony in 1810.
On 1 April 1816 Henry was appointed to a paid position as professor of vocalization (vocalisation). Among his students were Julie Dorus (c. 1821) and Cornélie Falcon (c. 1827–1828), who both later became leading sopranos at the Paris Opera. He became a professor of singing (chant) for a two-year trial (prior to 9 June 1835) and received his permanent position as professor of singing on 1 January 1837. He retired on 15 November 1842.
The first record of Henry having sung at the Opéra-Comique is on 29 June 1813 in the premiere of Boieldieu's opera Le nouveau seigneur de village. The singer's most noteworthy creations there included Gaveston in Boieldieu's La dame blanche (1825) and Sergeant Sulpice in Donizetti's La fille du régiment (1840). He also sang at the premiere of George Onslow's opera Le duc de Guise. He continued to appear regularly with the company until 1849.
