Yun Gi-jeong (1903 – 1955) participated in the proletarian literature movement as a novelist, literary critic, arts activist, and organizer. Born in Seoul, Yun was educated at the Boin School. He made his literary debut in 1921 with the publication of his short story “Memories of a Christmas” in the daily newspaper Joseon Ilbo. He participated in the leftist literary organization Yeomgunsa after its creation in September of 1922. After joining the Seoul Youth Group (Seoul Cheongnyeonhoe) in 1924, he worked with Ch’oe Seung-il, Song Yeong, Bak Yeong-hui, and others to unite the two leftist literary organizations Yeomgunsa and PASKYULA into a single entity. As the result of his efforts, he was appointed in 1925 as the inaugural secretary director and central committee member of the united group KAPF (Korea Artista Proletaria Federacio).
