Hermann Steiner of Sonneberg and Neustadt, Germany and in Bavaria, entered the doll market at the end of the German bisque doll era and began producing dolls around 1920. They are probably best know for their character baby or infant dolls, which were the doll of choice, at that time. A 1921 registered trademark name is My Pearl doll.
Hermann Steiner appears to have supplied dolls to Moses Kohnstam & Company, as their MOKO mark plus the HS Steiner mark have been found on dolls. H. Steiner's London agent was Boult, Wade & Tennant and in the USA the distributor was Roth, Baitz & Lipsitz.
In 1926 the company name was changed to Porzellanfabrik Hermann Steiner.
H. Steiner produced bisque, composition and celluloid doll heads with glass or painted eyes, molded hair or wigged with a body of cloth, kid leather or composition, black or white dolls.
