The Handbuch der Ernährungstherapie, a two-volume reference on dietetic therapy, stands as a primary academic contribution of Ernst von Leyden. An internist and neurologist born in 1832, he built his career within the Kingdom of Prussia, eventually becoming a notable figure in pathology and internal medicine through his roles at the Charité and several major German universities.
Academic and Clinical Career
Ernst von Leyden received his education at the Humboldt-Universität zu Berlin and the Friedrich-Wilhelms-Institut. His training was shaped by professors Johann Lukas Schönlein and Ludwig Traube. Over his career, he held professorships at the universities of Königsberg, Strasbourg, and Berlin. At Königsberg, he collaborated with figures such as Otto Spiegelberg and Friedrich Daniel von Recklinghausen. His mentorship extended to Hermann Nothnagel and Hermann Ludwig Eichhorst.

In 1880, he co-founded the journal Zeitschrift für klinische Medizin with Friedrich Theodor von Frerichs, followed by the Gesellschaft für innere Medizin in 1881. He played a formative role in oncology by initiating the first international cancer conference in Heidelberg in 1906. By 1908, he facilitated the establishment of the first international association for cancer research in Berlin. His clinical work included advocating for improved hospital facilities specifically designated for tuberculosis patients.
Medical Eponyms and Research
The research conducted by von Leyden remains linked to specific medical conditions. He is credited with identifying Leyden's neuritis, characterized by the replacement of nerve fibers with fatty tissue. Collaborative work with peers led to the identification of Charcot–Leyden crystals, observed in asthma and colitis patients. Other conditions bearing his name include the Leyden–Möbius syndrome, a form of pelvic muscular dystrophy, and the Westphal–Leyden ataxia, a childhood-onset condition. His scholarly output included extensive articles on tabes dorsalis and poliomyelitis.
