Daniel Peter was born in 1836, in Vevey, Switzerland. He was the son of a butcher, and is credited as the inventor of milk chocolate.
Daniel started out as a candlemaker by trade, but the advent of the oil lamp in the 1860s caused a downturn in the popularity of candles, leading the entrepreneur to seek another use for his candle factory.
Before he unlocked the secret to mixing milk with chocolate, Daniel became smitten with the eldest daughter of Swiss chocolatier François-Louis Cailler, Fanny. They married, and Daniel became more curious about chocolate as a possibility in his factory.
