Jeong Yak-yong (丁若鏞, August 5, 1762 (June 16, 1762) to April 7, 1836, 1836 (February 22, 1836) was a civil servant, writer, poet, philosopher, scientist, and engineer of the late Joseon Dynasty.
It contributed greatly to laying the foundation for modern engineering in the Joseon Dynasty. In addition, Jeong Yak-yong integrated the ideas of Silhak, which came down through the interests of Hyungwon and Seongho, into one body.
Books related to Neo-Confucianism, astronomy, geography, history, industry, and clothing, as well as "Gyeongse Youpyo," "Mokminsimseo," and "Humheum Sinseo" are all examples of social, economic, and ideological affairs, which can be said to be the result of "multi-academics."
In 2012, Jeong was selected as a UNESCO World Cultural Heritage along with Russo and Hesse.
