Besides Nestlé, several notable chocolate companies had their start in the late 19th and early 20th centuries. Rowntree's of York set up and began producing chocolate in 1862, after buying out the Tuke family business. Cadbury was manufacturing boxed chocolates in England by 1868. Manufacturing their first Easter egg in 1875, Cadbury created the modern chocolate Easter egg after developing a pure cocoa butter that could easily be molded into smooth shapes. In 1893, Milton S. Hershey purchased chocolate processing equipment at the World's Columbian Exposition in Chicago, and soon began the career of Hershey's chocolates with chocolate-coated caramels.
