Nineteenth century Paris was home to two important families of optical workers that had very similar surnames, Chevallier and Chevalier. Many published histories mix the two families together, incorrectly assuming that they were close relatives or, even, the same people. The family Chevallier, spelled with two “LL”, was made famous by Jean Gabriel Augustin Chevallier( 1778-1848), who was Optician to the King, and often signed his products “L’Ingéneur Chevallier”. The family Chevalier, spelled with one “L”, consisted of the father-son-grandson trio of Vincent Chevalier (1770-1841), Charles Chevalier 1804-1859), and Arthur Chevalier (1830-1872).
