Charles–Amédée Kohler (1790–1874) was a grocer in Lausanne, Switzerland, who began his career by trading ready–made chocolate. He eventually moved into manufacturing in 1830. Like Cailler and Suchard (two other brands of Swiss chocolate), he too strove constantly for improvements in the types of chocolate commonly available. One of his attempts gave rise to an important innovation: hazelnut chocolate. Together with his sons he produced this new speciality in Lausanne. This poster (ca. 1960) is an advertisement for one of Kohler´s best sellers, Chocolate with almonds and nuts.
