Cai Lun

Cai Lun (simplified Chinese: 蔡伦; traditional Chinese: 蔡倫; pinyin: Cài Lún; Wade–Giles: Ts'ai Lun) (ca. 50 AD – 121), courtesy name Jingzhong (敬仲), was a Chinese eunuch. He is traditionally regarded as the inventor of paper and the papermaking process, in forms recognizable in modern times as paper (as opposed to Egyptian papyrus). Although paper existed in China before Cai Lun (since the 2nd century BC), he was responsible for the first significant improvement and standardization of paper-making by adding essential new materials into its composition.
