蒙恬
In 250 BC, the Chinese general Meng Tian invented the ink brush. Meng Tian is perhaps better known for supervising the construction of the Great Wall of China. Meng Tian's brush consisted of actual camel hair, or sometimes rabbit hair, lashed to a wooden handle with twine. This brush was a great step forward in writing. Writing became much easier and the spread of calligraphy in China created the need for a cheaper and more plentiful medium to write on. This came in 105 AD with the invention of paper which in turn paved the way for the invention of printing.
