The medical career of Erwin Bälz within the Kingdom of Württemberg and later Tokyo spanned twenty-seven years, marking him as the longest-serving foreign government advisor in his field. Born in 1849 in Bietigheim-Bissingen, he became a central figure in the integration of Western internal medicine and anthropology into Japanese scientific institutions during a period of rapid state development.
Professional Tenure in Tokyo
Bälz completed his medical doctorate at the University of Tübingen before working at the University of Leipzig. In 1876, he accepted a contract with the Medical College of Tokyo Imperial University. Throughout his career, he taught more than 800 students and served as personal physician to Emperor Meiji and influential government figures, including Prime Ministers Itō Hirobumi and Yamagata Aritomo. His extended presence earned him the distinction of being the longest-serving Oyatoi gaikokujin advisor.
Anthropological and Medical Contributions
Beyond his teaching duties, Bälz conducted ethnological investigations across Korea in 1899 and 1903 alongside Richard Wunsch. He gained recognition for identifying the Mongolian spot in infants, which he attributed to Mongolian origins. Furthermore, his clinical observation of skin conditions led him to create a glycerin-based hand treatment known as Bälz Water, which was subsequently listed in the Japan Pharmacopoeia.

Bälz championed the therapeutic value of the volcanic springs in Kusatsu, comparing the site to the European resort of Karlsbad to promote it as a health destination. In addition to his medical work, he practiced kenjutsu under Kenkichi Sakakibara and explored jujutsu, later helping introduce judo to Germany. An avid collector, he gathered Japanese works now preserved at the Linden Museum in Stuttgart.
Final Years and Honors
After returning to Germany in 1905, Bälz continued his work until his death from heart disease in Stuttgart in 1913. He received high honors, including the Order of the Rising Sun, 1st class, and the Order of the Sacred Treasure, 1st Class. He is buried at the Stuttgart Forest Cemetery, and his posthumously published diary serves as a primary record of his decades spent abroad.
