Charles Lauth (born September 28, 1836 in Strasbourg , † December 2, 1913 in Nice ) was a French chemist.

Lauth studied chemistry in Strasbourg with Charles Frédéric Gerhardt and became an assistant (taxidermist) at the Conservatoire national des arts et métiers in Paris in 1856 . He worked at the Depouilly chemical factory in Clichy and then had a private laboratory in which he developed colorings and flavorings that he had produced in the factory of his friend Poirrier in St. Denis. From 1879 to 1887 he was director of the porcelain factory in Sèvres and from 1898 to 1905 director of the École supérieure de physique et de chimie industrielles de la ville de Paris, succeeding Paul Schützenberger .

In 1861 he developed the aniline dye methyl violet (Parisian violet), in 1871 methyl green and 1876 Lauth's violet. With Edouard Grimaux (1835–1900) he developed a method for the production of aromatic aldehydes in 1866, which he used to produce bitter almond oil, among other things. In 1866 he introduced copper sulfide as a catalyst in aniline black printing, which made the process of John Lightfood practicable.

In 1883 he was President of the French Chemical Society. In 1908 he became commander of the Legion of Honor .
