February 9th celebrates the world of Milton S. Hershey and the introduction of the Hershey bar. From the humble beginnings of a caramel manufacturer, Hershey paved the way to mass produce milk chocolate bars. It all started with a visit to the J. M. Lehmann exhibition of milk chocolate during the 1893 Chicago Fair. Hershey recognized an opportunity and purchased all the assembly equipment. After the close of the fair, the equipment was then shipped to Lancaster, Pennsylvania where he built his plant and town. Hershey stopped production of his caramels to focus solely milk chocolate production. After a lot of trial and error, by 1900 the first Hershey bar was introduced. Ahhh, sweet success.
