Hú Jìtáng 胡季堂 (1729–1800), Qiánlóng-period official; son of 胡煦 Hú Xù (1655–1736). After the loss of his father’s 99-juàn original Zhōuyì hán shū manuscript through pupil 李學裕 Lǐ Xuéyù’s premature death, Hú Jìtáng reconstructed the surviving material into the three component works that became the Sìkù-preserved Hú Xù Yì-corpus, including KR1a0145 Zhōuyì hán shū yuē cún.
