When the Swiss invented milk chocolate in 1875, the expensive luxury had a short shelf life. That changed in 1899 when Milton Hersey developed a process to mass produce the delicacy. He then built a plant and town now called Hersey, Pennsylvania. This facility produces the branded syrup, Kiss, Mr. Goodbar, Krackel and later acquired Reese’s and Twizzlers. In 1973, Hersey’s Chocolate World opened as an amusement park. The attraction offers rides and a tour of the chocolate making process. This is a haven for kids in a candy store.
