Kim Tschang-yeul (, 24 December 1929 – 5 January 2021) was a South Korean artist known for his abstract paintings of water droplets. He formed part of the Modern Artists' Association () in South Korea and joined the Art Informel movement of the 1950s and 60s. From the late 1960s, Kim Tschang-yeul presented works in international stages, studied in the United States, and eventually relocated to Paris in 1969, where he developed his signature water droplet paintings.

He is the father of French artist Oan Kim.

Early life Kim Tschang-yeul was born in Maengsan County, Heian'nan-dō, Korea, Empire of Japan in 1929. From the age of 5, Kim learned calligraphy from his grandfather and this experience later greatly impacted his artworks.Lewis Biggs, "Working with Nature", in Working with Nature: Traditional Thought in Contemporary Art from Korea (Seoul: Tate Gallery Liverpool, 1992), 11. He was also taught to sketch by his maternal uncle and decided to pursue a career as an artist.Yang, Hye-gyeong (January 2017). "Mulbang-ul, gil eul geotda majuchin jonjae". Supil sidae. 12 (72): 210. – via DBpia. After his hometown was taken over by the Soviet Civil Administration in 1946, he was arrested for possession of an anti-communist pamphlet, and left high school before graduating. After being held for 10 days, he fled to Seoul, which was under US control, and lived in a refugee camp for a year.

Art education After leaving school, Kim Tschang-yeul moved to Seoul, where he entered various private painting studios. He first joined Gyeongseong Painting Studio (Gyeongseong Misul Yeon-guso, 경성미술연구소) in 1947 to train under sculptor Lee Guk-jeon (이국전, 李國銓, 1915-?), but when the studio closed down, he learned painting from Lee Quede (이쾌대, 李快大, 1913–1965) at Seongbuk Painting Studio (Seongbuk Hoehwa Yeon-guso, 성북회화연구소).Hong, Yunri (March 2015).

Supil sidae. 12 (72): 211. – via DBpia Wanting to further his training, he enrolled in College of Fine Arts, Seoul National University, in 1948, but the onset of the Korean War in 1950 put a stop to his formal art education during his second year.Emma Patterson, "Anti-Art in Postwar Korea and Japan" (Master's thesis, London, Sotheby's Institute of Art, 2022), 17.Lewis Biggs, "Working with Nature", in Working with Nature: Traditional Thought in Contemporary Art from Korea (Seoul: Tate Gallery Liverpool, 1992), 8.

Post-war activities in South Korea and Art Informel As a result of the Korean War, Kim lost his sister, more than half of his classmates, and suffered from economic hardship for more than a decade.

Using his family's affiliation with the South Korean police force, Kim volunteered into the police force in 1951, and continued to work as a policeman until 1961.Kim, Chang-hwal (2016).

During this time, he was able to indirectly experience contemporary European Art Informel movement through Japanese painting albums, magazines, and art books. Even while working in the force, he submitted poems, paintings, and illustrations to the Police Academy's magazine, Gyeongchal sinjo ().Byeoldabi Kim and Yeong-mi Lee, "Kim Tschang-yeul ui 1950 nyeondae balgul jakpum gwa geu segye: Gyeongchal sinjo pyojihwa reul jungsim euro", Geundae seoji hakhoe, no. 21 (June 2020).Yun-jeong Lee, "Saero chajeun Kim Tschang-yeul ui geul 2 pyeon: Supil Inkeu, seutaendeu, heohwasoron Sigak eoneo raneun geot", Geundae seoji, no. 23 (2021): 184–93.

Kim Tschang-yeul was also the founding member of Hyeondae Misulga Hyophoe (현대미술가협회, Contemporary Artists Association, 1957) that demanded reform of the conservative Korean art field and the government-hosted National Art Exhibition of Korea (대한민국미술전람회, 大韓民國美術展覽會, also referred to as Gukjeon, 국전).Kyunghee Pyun, Jung-Ah Woo (2021). Interpreting Modernism in Korean art: Fluidity and Fragmentation. New York: Routledge. pp. 31. . Rejecting what was considered a "feudal and premodern system ruled by conservative juries," the group experimented with European Art Informel and American Abstract Expressionism, and labelled their exhibitions as the "anti-National Art Exhibition of Korea." While such Western movements had been motivated by the collective trauma of World War II, Kim Tschang-yeul argued that the suffering young Korean artists' experienced during the Korean War transposed foreign modes of expression into a unique Korean context.Kyunghee Pyun, Jung-Ah Woo (2021). Interpreting Modernism in Korean art: Fluidity and Fragmentation. New York: Routledge. pp. 31, 167. .

In the fourth Hyeondaejeon Exhibition () hosted by the Contemporary Artists Association in 1958, Kim exhibited his works alongside fellow members of the Contemporary Artists Association, such as Kim Seo-bong (김서봉, 金瑞鳳, 1930–2005) Kim Cheong-gwan (김청관, 金靑鱹, ?-?), Na Byeong-jae (나병재, 羅丙哉, ?-?), Lee Myeong-ui (이명의, 李明儀, 1925–2004), Lee Yang-no (이양노, 李亮魯, 1929–2006), Park Seo-bo (1931–), An Jae-hu (안재후, 安載厚, 1932–2006), Jang Seong-sun (장성순, 張成筍, 1927–2021), Jeon Sang-su (전상수, 田相秀, 1929-), Jo Dong-hun (조동훈, 趙東薰, ?~?), Ha In-du (하인두, 河麟斗, 1930-1989).Yun Jin-seop, "1970 nyeondae Hanguk Dansaekhwa ui taedong gwa jeon-gae", in Danseakhwa, mihak eul malhada: Chaeugo dasi biwonaen hoehwa (Paju: Maronie bukseu, 2015), 73. The exhibition gained immense attention and was interpreted by art critic Bang Geun-taek (방근택, 方根澤, 1929–1992) as the collective emergence of Korean Art Informel.Yun, Jin-seop (2000). Hanguk Modeonism misul yeon-gu (in Korean). Seoul: Jaewon. p. 29. .

Although Kim left the Korean art scene in the 1960s, he is still credited as forming part of the first generation of Korean Dansaekhwa artists, and has participated in various Dansaekhwa group exhibitions, both in South Korea and abroad.Seo Jin-su, "Dachaeroun Dansaekhwa misul sijang, gyeongmae sijang, hwarang jeonsi, ateu peeo", in Danseakhwa, mihak eul malhada: Chaeugo dasi biwonaen hoehwa (Paju: Maronie bukseu, 2015), 35–46.Jeong Yeon-sim.

International art scene After leaving the police force, Kim worked as a teacher at Seongru Art School () and gradually turned to the international art scene. He continued to submit works to the second and third Paris Biennale in 1961 and 1963, and the São Paulo Biennale in 1965, and received a grant from the Rockefeller Foundation to study as a member of the Art Students League of New York from 1966 to 1968.

Kim Tschang-yeul was then able to participate in the Paris Avant Garde Festival with the help of Paik Nam June in 1969, after which he permanently relocated to Paris and married Frenchwoman Martine Gillon.Lim, Kate (2014). Park Seo-bo, from Avant-garde to Ecriture. Singapore: Booksactually. p. 184. .

Kim Tschang-yeul's participation in the Salon de Mai in Paris, 1972, was the most critical turning point in his career. For this exhibition, he submitted the famous water droplet painting, Event of Night (Événement de la nuit, 1972), which gained critical acclaim.

For the rest of his career and life, Kim continued to produce series of water droplet paintings that incorporated "water droplets set against stark, neutral, monochromatic backgrounds in a way that conjoins figuration, hyperrealism, and abstraction."

The attention received from the water droplet paintings was a great reward after almost a decade of inconspicuousness in the French art field. In a 1974 letter to friend and fellow artist Park Seo-bo, Kim Tschang-yeul wrote: "I have not had a single show for the last 10 years, but now all of a sudden so many shows are scheduled."

Indeed, throughout the 1970s, Kim Tschang-yeul participated in numerous group exhibitions as well as holding solo shows, which continuously built up his recognition in Europe, America, Canada, and Japan, and his works were represented at prominent art fairs like Art Cologne and Art Basel.Lee Ufan, "Current Status of Korean Contemporary Art: Interview with Lee Ufan", in Dansaekhwa 1960s-2010s: Primary Documents on Korean Abstract Painting (Seoul: Korea Arts Management Service, 2017), 60.

In the 1980s, Kim Tschang-yeul engaged in several prominent types of water-drop series, including the Poem of 100 Characters () and Recurrence ().Lee Sang-gyu, "Hanguk bigusang gyeyeol jakga ui 2005 nyeon ihu gyeongmae donghyang", Misulsa wa munhwa yusan 9 (December 2020): 106.

Water droplet paintings Critical analyses of Kim Tschang-yeul's paintings often refer to the subject of water droplets as multi-layered images of cleansing, purification, and "the evanescence of individual life." In deciphering the water droplet paintings, Biggs explains that the trompe l'oeil or ultra-realist painting technique used in Kim Tschang-yeul's works "is counter-balanced by his use of canvas (or newspaper) to represent itself" as the "strange cubist mixture of the real standing for itself and the painted standing for something else is complicated further in the works with Chinese characters, where the characters act as ground but the 'ground' has a message far more graphic and elaborate (for those who can read it) than the painted representations."

Lee Il (이일, 李逸, 1932–1997), a celebrated art critic known for his works on Korean Dansaekhwa, similarly underscored the significance of both the canvas and the image sketched on it: "The Chinese calligraphy of The Poem of 1000 Characters and the water drop images form an intimate and reciprocal relation. In other words, the Chinese characters are not simply laid out as a (back)ground, but actually serves as a cover for the water drop images."Lee Il, "Preface, HyunDai Gallery Catalogue September 1990" in Working with Nature: Traditional Thought in Contemporary Art from Korea (Seoul: Tate Gallery Liverpool, 1992), 51.

The active employment of background of the canvas, paper, or any other material, in the formation of artistic expression, rather than a mere surface, is a common interest among Dansaekhwa artists. In Kim Tschang-yeul's works, "the water drops are not merely attached to the surface of a canvas, but rather fully entrusted to the canvas."Nakahara Yusuke, "Facets of Modern Korean Art", in Dansaekhwa 1960s-2010s: Primary Documents on Korean Abstract Painting, trans. Ahn Won-chan (Seoul: Korea Arts Management Service, 2017), 89–90.
