Yu Hyeong-won

He was a Neo-Confucianist and science scholar of the Korean Joseon Dynasty.

He was a Korean pioneer of the early silhak ("practical learning") school[1][2] as well as a social critic and scholar of the late Joseon period.

He was the disciple of Misu Heo Mok and second cousin of the silhak scholar Seongho Yi Ik.

His work, Bangyesurok, became influential during the reign of King Yeongjo, who was made aware of it in 1741 and authorised its printing in 1770.
