Hello, I'm an expert in the history of confectionery and food innovations. Let's delve into the history of the chocolate bar.

The very first chocolate bar is often attributed to Joseph Fry, a British Quaker, who in 1847 discovered a way to mix chocolate with sugar and other ingredients to make it more solid and less expensive. This innovation allowed for the production of chocolate in bars and made it more widely available to the general public.

Now, let's translate that into Chinese:
