Chocolate bars

In 1847, Joseph Fry discovered a way to mix melted cacao butter with cocoa powder and sugar to create a molded chocolate bar. Adding to this several years later, Milton S. Hershey installed in his factory a chocolate-making machine he saw on display at the 1893 World's Fair and produced the first chocolate bars. Hershey began selling the first mass produced candy bar, the Hershey Bar, in 1900.
