Chocolate's patent was granted by George ii in 1728 to Walter Churchman a pharmacist from Bristol, England. Chocolate had been drunk for many years (from 1000BC by the Aztecs) and it was recommended by pharmacists for its medicinal properties and used to mask the flavour of other medicines. The manufacture of chocolate on a commercial scale began in Bristol in 1756 and was the brain child of Dr Joseph Fry who took over Walter's shop on the death of his son Charles Churchman. Fry's chocolate later merged with Cadbury's in 1919. Cadburies still produce some Fry's bars but to much altered (sweeter)recipies.
