Denis Albert Bardou (15 February 1841 – 14 March 1893)[1] was a French manufacturer of precision optical instruments.
He was born in Paris, the son of Pierre Gabriel Bardou, optician, and Gertrude Aglaé Anna Guichard.
Denis Albert's grandfather had founded the Maison Bardou in 1819, an optical company in Paris, which had then passed to his father.
The company manufactured and sold astronomical telescopes, spyglasses, binoculars, microscopes and opera glasses.
[2] The Maison Bardou and its fellow Paris-based competitors the Secrétan and Mailhat companies were among the leading French precision optics manufacturers of the early twentieth century.
