萧何
The authorship of the law is most commonly attributed to Xiao He. The Book of Han noted that after the Han Dynasty was established at 206 BC, emperor Liu Bang thought the wartime three treaty laws are inadequate for the crimes, and the Book of Jin recorded that Chancellor Xiao He adapted law code from the Qin Dynasty code and added 3 more chapters. The law got its name from the 6 chapters adopted from the Canon of Laws and 3 new chapters covering family register, conscription and livestock.
