Daniel G Chase had two brothers named Oliver and Silas. Oliver had a pharmacy which in those days would use a lot of sugar to enhance the taste of medicine. As part of his business he make lozenges from gum Arabic, peppermint and brown sugar. In order to expedite his production in 1847 he invented the very first candy manufacturing machine in the United States. It was called a Lozenge Cutter. Then in 1850 Oliver invented a machine that would pulverize sugar. His candy business began to grow rapidly. He enlisted his brother, Silas joined him in this new candy manufacturing enterprise. The two brothers formed the “Chase and Company”, which later became the New England Confectionery Company, or NECCO Wafer.
Daniel G. Chase joined his brothers in their candy company. According to the company history web page he invented the method of printing on candy hearts, which has become a standard during February’s Valentine season.!!!
