Yáng Tǎn 楊倓 (1120–1185), zì Zǐmò 子默, of Dàijùn 代郡 (modern Yùxiàn 蔚縣, Héběi). Southern-Sòng official and medical compiler. Son of Yáng Cúnzhōng 楊存中 (c. 1102–1166), the senior Southern-Sòng military commander known posthumously as Héwǔ Gōngwáng 和武恭王. Yáng Tǎn took the civil-official track; his career included major prefectural and Hanlin Academy appointments, culminating in his service as Surveillance Commissioner (guānchá 觀察) at Dāngtú 當塗 (modern Ānhuī, also known as Gūshú 姑孰), where he compiled and printed his family’s medical collection. The family medical interest spans three generations; what he printed was a multi-generational accumulation supplemented with his own clinical experience.
