Baron Charles Gustave Martin de Chassiron (1818-1871) was a French diplomat of the 19th century.
He travelled to China and Japan as one of the two Attachés of the French Embassy under Baron Gros, with the title of "Detaché extraordinaire en Chine et au Japon" from 1858 to 1860,[1] together with Marquis Alfred de Moges.
Chassiron wrote an account of his travels Notes sur le Japon, la Chine et l'Inde: 1858-1859-1860.
[2][3] During his travels, Chassiron built a large collection of Japanese and Chinese artifacts which are displayed today at the Orbigny-Bernon Museum in La Rochelle.
After his death his widow remarried that same year with a wealthy Englishman, John Lewis Garden, and had two daughters from him.
