Wàn Sītóng 萬斯同 (1638–1702), zì Jìyě 季野, hào Shíyuán 石園. Native of Yīnxiàn 鄞縣 (modern Níngbō 寧波, Zhèjiāng). Major early-Qīng historian and Míng-loyalist; pupil of Huáng Zōngxī 黃宗羲 (1610–1695) and a leading representative of the Zhèdōng shǐxué 浙東史學 (“Eastern Zhè historical school”). Younger son of Wàn Tài 萬泰 (字履安), a major late-Míng official. Wàn Sītóng held no Qīng office (a deliberate refusal as a Míng yímín) but was widely consulted in his role as the principal bùyī (commoner-scholar) advisor to the Kāngxī-era Míngshǐ guǎn 明史館 from 1680. He composed (without remuneration and without putting his name to the official text) the bulk of what became the early-Qīng draft Míngshǐ gǎo 明史稿 — a text that became the principal foundation for the imperial Qīndìng Míngshǐ (KR2a0026) of 1739; the substantial overlap was much commented on by Qīng kǎozhèng scholars. His own published works include the Míngshǐ gǎo 明史稿 (in 416 juǎn; the unofficial draft), the Lìdài shǐbiǎo 歷代史表 (KR2d0021) supplying biǎo for the histories that lacked them, the Rúlín zōngpài 儒林宗派 (a doxographic work on the Confucian schools), and the Qúnshū yíbiàn 群書疑辨 (textual-critical notes). Substantial epitaph (shéndào bēi) by Qián Dàxīn 錢大昕; Huáng Zōngxī’s preface to the Lìdài shǐbiǎo (1692) is preserved in the WYG witness. CBDB id 34178, dates 1638–1702 (confirmed). The Sìkù tíyào of KR2d0021 gives the lifedates from his zì Jìyě as deriving from Yīnxiàn; the catalog meta agrees.
