Yi Bingheogak (24 February 1759 — 3 March 1824[1]) (floruit 1809), was a Korean writer.
She was born on 24 February 1759 into the Jeonju Yi clan (전주 이씨, 全州 李氏), when Yeongjo was in his 35th year of reign, to a family of scholars. Her father, Yi Chang-su, was a 13th great-grandson of King Sejong through his 12th great-grandfather, Prince Yeonghae. Her father was a gamsa (監司) who dealt with the administrative affairs of Pyongyang. Her mother was Lady Ryu of the Jinju Ryu clan, aunt of writer Ryu hui who was known for his work Muntong (文通).
Yi married writer Seo Yu-bon at the age of 15 in 1773. Seo's family on his maternal side was part of the political faction Soron. It is recorded in Seo's work Jwasosaninmunjip (左蘇山人文集) that Yi's talent in poetry was at a level where the two could exchange Chinese poetry with each other.[2] Life grew harder for Yi as a result of Seo's early retirement amidst political troubles, so she cultivated a tea garden to get out of poverty.[2] Her work Gyuhap chongseo was written then.[2] After Seo died in 1822, she wrote Jeomyeongsa (絶命詞), a poem about the end of life (in this case her husband's) for her husband. She did not comb her hair or wash her face and remained in her house. She died in 1824 at age 66, 2 years after Seo's death.[2]
She published the women's encyclopedia Gyuhap chongseo about household tasks in 1809. She was one of very few published women in Joseon-dynasty Korea, alongside poet Seo Yeongsuhap (1753–1823), and Confucian philosopher Im Yunjidang.
