Cai Lun
Cai Lun (c. 63-121 CE) was a court eunuch of China's Eastern Han dynasty who perfected the manufacture of paper from bark, hemp waste, old rags, and fishnets, presenting his invention to Emperor He in 105 CE. Known as 'Marquis Cai's paper,' his product was lighter than bamboo strips and cheaper than silk, transforming how humanity records and transmits knowledge.
