孫繼沖

Sūn Jìchōng, grandson of 刁質明 Diāo Zhìmíng; supplied a brief verse-postface to KR3em038 Hóukē jiāxùn 喉科家訓 dated mid-November 1924 from the family clinic Yánshòu yīshì 延壽醫室.

Note: the prefatorial signature gives “Sūn Jìchōng” — sūn 孫 here meaning “grandson” rather than the surname Sūn — so the figure’s surname is likely Diāo. The conventional Persons-file name 孫繼沖 is retained for stable wikilinks.
