"Edmé Samson (b Paris, 1810; d Paris, 1891), founder of the porcelain firm Samson, Edmé et Cie (commonly known as Samson Ceramics), was a famous copyist ...
(and perhaps forger) of porcelain and pottery. The firm produced high-quality copies or imitations of earlier styles of porcelain, mainly 18th-century European and Chinese and Japanese porcelain, but also earlier styles such as Italian maiolica." - (Wikipedia (en) 31.08.2022)
"Edmé Samson (1810-1891) founded the ceramics firm with the intention of making reproductions of ceramics on display in museums and private collections. The firm did not set out to deceive and claimed that all the reproductions they produced were distinctly marked to avoid confusion. The porcelain decorator partnered with his sone Emile (1837-1913) and opened a warehouse in Montreuil where between 1864 and 1870, they began to produce porcelain. During the nineteenth century they reproduced ceramics from a variety of sources including Italian faience and majolica, Persian style dishes, Hispano-Moresque pottery, Pallissy copies and the Meissen, Sevres, Chelsea, Worcester and Derby factories. They also copied early Quing dynasty famille rose, famille vert Chinese porcelains and Japanese 'Imari' wares. Samson wares were produced in hard-paste porcelain, while many of the originals would have been in soft-paste porcelain. They also used an 'Ss' mark to distinguish Samson pieces from genuine objects. Nevertheless, in later years many Samson productions have been confused with their originals, especially if the mark has been removed. They continued to produce porcelain and pottery until 1969, and sold the works and contents in 1980." (https://www.britishmuseum.org/collection/term/BIOG78030, 31.08.2022)
