Charles Unsinger (June 11, 1823 - March 7, 1891) was a French printer and typographer. He was born in Strasbourg and apprenticed under the printer Gustave Silbermann, who sent him to Paris in 1851. There, Unsinger worked as a proofread at the publisher Plon. From 1867 to 1871, he managed the Berger-Levrault printing workshops in Metz and Nancy. Returning to Paris in 1873, he took over the management of Jules Claye's machine workshops. In 1877, upon Claye's retirement, he set up his own business on the Rue du Bac and was assisted by his son-in-law Frédéric Emile Kapp (1851 - 193?). who also had his own firm specializing in letterpress and chromolithography.
