Kämmer & Reinhardt
Information taken from: https://www.dollreference.com/kammer_reinhardt_dolls.html
The Kämmer & Reinhardt doll company was formed in 1886 in Waltershausen, Thuringia, Germany by Ernst Kämmer and Franz Reinhardt.
Early K & R dolls were made of wax. K & R bisque doll heads and bodies were designed by them, but most heads were manufactured by Simon & Halbig which is why heads bear both marks. They also purchased heads from Kling and Schutzmeister & Quendt.
From 1886 to 1909 K & R made only dolly faced dolls with a bisque head on a composition ball jointed or kid body, many with an open mouth and teeth. After 1909 they made many types of dolls; bisque, composition or celluloid heads and even cloth costume dolls with wired bodies dressed in various professions.
K & R supplied some bisque heads used to make Emile Berliner's gramophone talking dolls in 1890-1894. In 1902 K & R purchased the Heinrich Handwerck doll company and about 1920 they acquired the Simon & Halbig company as well.
K & R is probably best known for character baby and child dolls.
