Li Shicai, a famous physician of Ming Dynasty had a large number of students. Shen Langzhong, who was a student of Li Shicai, was the teacher of Ma Yuanyi, and one of Ma's student was You Zaijing. This inheritance pedigree was called "Li Shicai School" in academic communities. There were little of study on its later physicians after You Zaijing. This paper collated the medical works, genealogy, local chronicles and medical records of Li Shicai and doctors of different generations. We clarified the academic inheritance genealogy of the past four hundred years. Up to now, there have been twelve generations totally.
明末著名医家李士材，门人众多，其学术一传沈朗仲，二传马元仪，三传尤在泾，学界称之为"李士材学派"。既往学者对李士材学术传承谱系研究限于四代之内，自尤在泾之后未有涉猎，不够系统全面。整理李氏及各代门人医家的医著、家谱以及地方志、医人志等文献资料，厘清400年间的学术传承谱系，至今有12代。.
