The Suchard chocolate factory took off thanks to his son Philippe (1834–1883), then to his son-in-law Carl Russ (1838–1925), who ran the chocolate company from 1884 to 1924. After Philippe's death in 1884 in Neuchâtel, his daughter, Eugénie Suchard and her husband Carl Russ-Suchard, took over the functioning of his factory. Carl Russ-Suchard opened the first Suchard factory abroad in 1880 in Germany, at
Lörrach. The Suchard factory used
hydropower of the nearby river to run the mills. A grinding mill consisting of a heated
granite plate, and several granite rollers moving forwards and backwards were used to produce chocolate. This design, the
melanger, is still used to grind
cocoa paste. As a result, chocolate became more affordable. Before opening his factory, Suchard realized that a small tablet sold at a pharmacy was worth three days' wages. However, chocolate was still an expensive product, therefore limiting the number of potential customers. Suchard struggled financially early in his career as a
chocolatier. His success came in 1842, with a bulk order from
Frederick William IV, king of Prussia, who was also the prince of
Neuchâtel. This triggered a boom, and soon his chocolates won prizes at the London
Great Exhibition of 1851 and the Paris
Universal Exposition of 1855. By the end of the 19th century, Suchard had become the largest chocolate producer. In 1896, inspired by the success of
Daniel Peter, Carl Russ-Suchard created a first milk chocolate bar. In 1901, the company mechanized its production and launched the
Milka chocolate brand for the Swiss market. Carl Russ-Suchard combined an unusual purple packaging with a
Simmental cow symbolizing their use of milk. Having become a public limited company in 1905, Suchard was transformed into a holding company in 1930, marking the end of the family business after Willy Russ had sold his shares. Suchard continued its development abroad as well as on the Serrières site (30 kg of chocolate per day in 1826, 60 tons in 1924; 100 workers in 1875, 920 at the end of the 1960s) and diversified its products with various brands such as Suchard Express (a chocolate drink) and
Sugus (fruit candies). ==Mergers==
