Zhāng Zìchāo 張自超 (1660–1717), zì Yítàn 彝歎, native of Gāochún 高淳 (Yìngtiān fǔ 應天府, modern Jiāngsū). Kāngxī guǐwèi (1703) jìnshì. He was an early-Qing exponent of Chūnqiū studies along orthodox Zhū Xī lines but tempered by sober evidential reading; the Sìkù editors note that his work is “no mere disciple-collected miscellany” but the product of independent scholarship. His Chūnqiū zōng zhū biàn yì 春秋宗朱辨義 (KR1e0109) was the principal source mined by Fāng Bāo 方苞 in writing his Chūnqiū tōng lùn (KR1e0110) and Chūnqiū zhí jiě / Chūnqiū bǐ shì mù lù — a fact registered in the Sìkù tiyao. The catalog has no birth/death dates; CBDB gives 1660–1717, followed here.
