蔡伦
In China, the early material was animal bones, later silk, bamboo and wooden slips, until the 2nd century when paper was invented. The invention of paper is attributed to a eunich of the imperial court called Cai Lun in 105 A.D. However, paper wasn't introduced to Europe for another thousand years following a battle in 751 A.D. where a few paper-makers were captured and thus the technology spread from Baghdad westward, only reaching Spain in the 12th century.
