The speaking chocolate was a joint development of the American inventor Thomas Alva Edison and the German chocolate producer Ludwig Stollwerck : a phono Graf , the record of chocolate was happening.
history
Edison and Stollwerck met in 1893 during the World's Columbian Exposition in Chicago. Stollwerck was enthusiastic about Edison's inventions, Edison liked Stollwerck's marketing ideas and the “chocolate temple”, which showed a 12 m high replica of the Germania of the Niederwald monument made from 300 quintals of chocolate.
Thomas Alva Edison and Ludwig Stollwerck founded the "Deutsche Edison Phonograph Compagnie" with other shareholders in 1895, based in Cologne. Together they developed the “Talking Chocolate”, a play phonograph made especially for children from sheet metal that played music from a chocolate record.
This phonograph was produced in 1903 under the name Eureka . It was a sensation in the Christmas business and was downright ripped out of the dealers' hands. The model A , with a hand crank, cost 1 mark, the model K , with a windable clock mechanism, cost 6 marks, the chocolate record in "Quality Extra-Tender" and with over 100 different songs cost 60 pfennigs each.
Ludwig Stollwerck had already acquired utility model protection from the Viennese mechanic Theodor Lotha in 1902 via a phonograph plate "which is coated on both sides with a thin layer of a material suitable for registering and reproducing sound waves".
In 1904 Stollwerck produced a successor model with an elegant wooden case and brass fittings that could also play hard rubber records. Both phonographs are coveted collector's items today.
