In 1847 J.J Fry yes him of Fry's Turkish Delight he invented the chocolate bar as we know it to-day but I think it was the Cadbury brothers who first wrapped them. I know for sure that they were the first to present boxes of chocolates that was for Valentines Day in 1861 nad they came in a heart shaped box. Hope this answers your question.

There are two people who the most often credited with creating the first wrapped chocolate bar. Who really did, no one knows. And whether there was chocolate of a wrapped kind not in a bar form prior to this isn't really known. But this period, well, bar shape or not, chocolate is generally referred to as a bar, because it's when people began creating chocolate that could be eaten. Before this period, chocolate was for drinking really. The two differing stories: The Freia company, credited with creating the first wrapped chocolate bar (and it's still being produced), the Freia Melkesjokolade, in Norway, 1906. The Ganong Brothers. Arthur Ganong is credited with being the first to make any sort of a wrapped chocolate bar; selling the first chocolate bars in 1910. In 1920 they began using the brand name "Pal-O-Mine" for their chocolate bar. But, they are only two of many people in a line credited with inventing the chocolate bar. They're actually last in the line--the line starts with Francois-Louis Cailler in 1819. Practically a century earlier. None of the other people who created the chocolate bar have a mention, that I know of, of wrapping the chocolate, at least not until much later when they went into different types of production. See my answer at this question (http://www.answerbag.com/q_view/741784) for the long explanation as to who invented the chocolate bar. Basically, in answer in your question, the Ganong Brothers and the Freia company are the two most commonly credited with creating the first wrapped chocolate bar. Whether one of the chocolate bars that existed before then was wrapped in some fashion, how it was if it was, no one knows. Or they do, but it's in an anecdote somewhere really random and will take chocolate historians years to find.
