Sigismond Jaccoud

Swiss physician (1830–1913)

The publication of a three-volume pathology work in 1883 totaling nearly 3,000 pages established Sigismond Jaccoud as a primary authority in French internal medicine. Born in Geneva in 1830, he navigated a career path that transitioned from early studies in music and literature to a central role in the medical faculties and hospital networks of nineteenth-century Paris.
