Boyer was a French optical company based in Paris. It was founded in 1885 by Antoine Boyer, then sold in 1925 to André Levy (1890-1965), a former sales manager at the Lacour-Berthiot company. His wife, Suzanne Lévy-Bloch (1894-1974), was a brilliant mathematician and optician, graduated from the École Supérieure d'Optique where she attended Henri Chrétien's classes. From then on, she was the chief designer of the Boyer lenses (according to D. Fromm and E. Beltrano). After bankruptcy at the beginning of the 1970s, the factory was bought out by M. Kiritis and the former owner of the Roussel optical company. It lasted a decade more with reduced workforce and production, then definitively closed in 1982.
