Daniel Peter (1836–1919) was a famous Swiss chocolatier. He was the first person to make a milk chocolate bar, in 1875.[1] M. Peter began his career as a candle maker in his native Vevey, Switzerland, but soon demand fell due to the emergence of oil lamps.
When Peter invented the process of making milk chocolate in 1857,[1] he had a problem with removing the water from the milk, which caused mildewing. Not till he enlisted the cooperation of Henri Nestlé, then a baby-food manufacturer, was he finally able to bring the product onto the market in 1875, after seven years of working on it. Later, in 1879, the two went on to form the Nestlé Company.
