Born in South Korea, Ha Chong-Hyun emerged as a significant voice in the Korean avant-garde during the 1960s. His early career was marked by experimentation with geometric abstraction and a persistent interest in challenging the traditional boundaries of painting and material application.

He is most widely recognized for his Conjunction series, which he began in 1974 and continues to develop today. This body of work is defined by his signature technique of pushing oil paint through the back of coarse hemp canvas, creating textured, monochromatic surfaces that emphasize the physical interaction between medium and support.

Ha remains a central figure in contemporary art, with his work receiving sustained international attention. Recent institutional focus includes a major six-decade survey at Lisson Gallery in London, which highlights the evolution of his practice from early geometric compositions to his mature, material-focused abstractions.
