Jacob Winslow was a Dutch born, French naturalized anatomist and physician whose contributions to medicine are abundant. His importance to medicine is undisputed. His personal life included a religious crisis that resulted in his estrangement from his family, but afforded him patrons in Paris to continue his work. Following this conversion, he changed his name to that of his catechist and was rechristened Jacques Benigne Wilson. His respect as an expert was well deserved, and he held several prominent positions during his career in Paris. His main work, Exposition anatomique de la structure du corps humain, was published in 1732 and is considered the first purely anatomical treatise. This review highlights his contributions to anatomy and medicine through the course of his career.
