Main scientific work
Japanese scientists said that there were 921 species of Korean butterflies but he made a great effort to collect 160 mil of cabbage butterflies throughout the Korean peninsular and compared their patterns and measured the length of front wings with a ruler by himself. He drew a conclusion that even though the wing patterns are different, they might not be different species and got rid of many wrong scientific names posted by Japanese prematurely and proved that they are individually changed adapting to surroundings and classified Chosun butterflies into 248 species. He longed for Chosun independence so he set the first stone for the classification of Chosun butterflies through his enormous samples he labeled butterflies Korean name and add seok. Especially he named an undiscovered butterfly the Fluttering Butterfly of the Jirisan Mountain for the first time in the world. In 1940 ''A Synonymic list of butterflies of Korea'' was published by The Korea Branch of the Royal Asiatic Society. It was the first time for a Korean to be sponsored by the British Royal academy. After that, he was selected as a regular member of world entomology. Throughout his entire life, he had collected 750,000 butterflies samples and sorted and marked the locations on the Korean maps and world maps each way. When theLater activities and death
He wrote a small dictionary ''Lernolibro de Esperato Kun Vortaeto'' 1947 because he was deeply involved in international peace movement to resist Japanese imperialism. He didn't change his Korean name into Japanese name until liberation. He voluntarily transferred to the Jeju natural medicine laboratory in Seogwipo, Jeju Island in 1943. While he had been working here for two years, he was fascinated by particularity of Jeju culture and absorbed in Jeju exploration. Six general books: Jeju dialect, Jeju population, Jeju document, Jeju essay, history of Jeju insect, and Jeju data, were published. These are valuable resources for Jeju study. After liberation, he was in charge of zoology of the national museum. During the Korean War, he was mistaken as one of North Korea's People's Army and got shot by a drunken man, in front of a theater in Seoul while he was going to the national museum which was burnt by a bombing attack. It was said that just right before his death, he shouted "I know butterflies only!"Jeju Studies
Relationship between Seok Jumyeong and Jeju Island
:According to the historical records, Seok Jumyeong has visited Jeju-island three times. On his first visit, he went to catch butterflies for specimens from July 21st, 1936, for a month. This is recorded in his own book, Zephyrus, vol 7, page 150 to 174. Next Visit was for working 2 years at a Research Institute of Herbal Medicine attached toJeju studies by Seok Jumyeong
:He has stayed in Jeju Island from July 21, 1936 to August 22, 1936, collecting butterflies for a month. Zephyrus, vol.7, 1937 is the typical record of it. According to the records of that period, we could confirm that his interest wasn’t just the collection of butterflies, also the Jeju Island's urban and rural areas such as Gappa Island and Seop Island, and the nature of Jeju Island like 500 Generals, Halla Garden and Sanjung River. :On his second visit, Seok Jumyeong left Jeju Island in May 1945 and analyzed the data in Gaeseong and Seoul and organized it into six volumes of the Jeju Island series(제주도총서). The plan to publish the Jeju Island series is well documented in the preface of the "Jeju Island Data Collection," which he defected in June 1950. :Seok-Jumyeong wrote six books about Jeju Island. Of these books that have been issued since 1947, Jeju Island Dialect Vol. 1, Jeju Island Life Research Vol. 2, and Jeju Island-related Literature Vol. 3 were published by Seoul Newspaper during his lifetime. The purpose of this study is to review the significance of the publication of a series of studies on Jeju Island and the relationship between the book author"s Jeju Island studies and local research. Seok-Jumyeong read every resource on Jeju Island and thoroughly collected it in the course of writing his Jeju Island series.Significance of Jeju Island series written by Seok Jumyeong
:A look at the contents of this series indicates its consideration allowing us to get a wide knowledge of its field, as it provides collected and integrated resources pertaining to the same kind of knowledge regardless of any trace containing any resource. In addition, this series enables us to carry out comparative studies by arranging similarities or differences so that we can contrast them simultaneously. In the situation prior to 1950,when the concept of local research was not yet established in our country, a Jeju Island series by JuMyoung-Seok contributed to founding local studies into a single integrated body of knowledge now referred to as the "Jejudo Study."References
