Yu Kil-chun

Yu was born on November 21, 1856 in Seoul, Joseon.[1] He is of the Gigye Yu clan.[2][1] He was born the second son of Yu Jin-su and his second wife, Lady Yi of the Chungju Yi clan.

At an early age, he learned the Chinese classics from his father and his maternal grandfather, Yi Gyeong-jik. In 1870, at age fourteen, Yu joined the circle of Park Gyu-su who was also a trusted friend of the late Crown Prince Hyomyeong, a leading scholar of Bukhak (북학; 北學; lit. northern studies), a school within the Silhak social reform movement.[2][3] The movement advocated for learning from abroad in order to reform the country, which was an unconventional idea in Joseon at the time. He quickly adopted an interest in reading foreign books.[3]

In 1881, he was sent to Japan as an attendant of a Joseon foreign mission. While there, he was allowed to remain in Japan and study abroad for a year at the Keiō School (later "Keiō University").[3][2] This made him the first Korean exchange student to Japan.[2] When the Imo Incident occurred in 1882, Min Yeong-ik recommended that Yu return to Korea, which he did in January 1883.[2]

Yu was among the first Koreans to ever set foot in North America.[2] In July 1883,[2] Yu traveled as an attendant to Min as part of the first Korean mission to the United States. While there, he again remained to study abroad. He stayed for around a year and a half thanks to the patronage of the American zoologist Edward S. Morse, whom he had previously met while in Japan.[3][2] In Fall 1884,[2] he enrolled in the Governor Dummer Academy in Byfield, Massachusetts.[3][2] This also made him the first Korean to study abroad in the United States. However, his studies were once again halted due to another incident in his home country: the Gapsin Coup. He halted his studies in December 1884, and returned to Korea via Europe.[2] He stopped by a number of major European countries along the way.[2][3]

However, upon his return to Korea, he was viewed with suspicion due to his association with members of the pro-reform Gaehwa Party. Yu was then arrested. With the assistance of Han Kyu-seol, Yu was eventually able to escape a verdict of capital punishment, and was allowed to serve his sentence at Han's house until 1892.[2]

While in detention, Yu wrote a book on his experiences entitled Observations on Travels in the West (서유견문; 西遊見聞; Seoyu Gyeonmun) and published it in 1895. The book is nearly 600 pages long,[4] and is written in a mix of hangul and hanja, and introduces Western civilization to Korean audiences. It advocates for a number of reforms, including the establishment of a constitutional monarchy, military reforms, international trade, and a modern currency and tax system. It also discussed ideas such as the social contract. These ideas later became a significant inspiration for the Gabo Reform.[2][4]

At the end of the Donghak Peasant Revolution and the First Sino-Japanese War that followed, Yu worked in the government as part of a pro-Japanese faction.[2] From 1894 to 1895, Yu worked for the government under Prime Minister Kim Hong-jip, who intended to modernize Korea. In 1895, he became Vice Minister of State for the Home Office.

In 1895, he published the first Korean dictionary and grammar book.[lower-alpha 1][1]

In October 1895, following the assassination of Empress Myeongseong, Yu contacted Inoue Kaoru, the Japanese Minister for Foreign Affairs, to discuss the incident. In February 1896, during Gojong's internal exile to the Russian legation, the pro-Japanese faction collapsed, and Yu fled to Japan. Yu and a group of young Korean graduates of the Imperial Japanese Army Academy attempted to execute a coup d'état against the Korean government, but the attempt failed. This sparked a diplomatic row between the two countries, and Yu was subsequently imprisoned on the Ogasawara Islands. Yu was eventually allowed to return to Korea in 1907, when Gojong was dethroned. Yu then served as the vice chair of the Young Korean Academy.[2][1]

In 1909, Yu wrote and published a book on Korean grammar.[2][lower-alpha 2]

When Korea was annexed by Imperial Japan in 1910, Yu opposed the annexation. He declined the Danshaku title he was awarded by the Japanese government.[2][lower-alpha 3] He then fell into a depression.[2][1]

On September 30, 1914, he died from complications of a kidney disease.[1]
