Summary
Updated 2026-07-21

Udagawa Yōan was a 19th-century Japanese scholar of Western studies, or "Rangaku". In 1837, he published the first volume of his Introduction to Chemistry , a compilation of scientific books in Dutch, which describes a wide range of scientific knowledge from the West. Most of the Dutch original material appears to be derived from William Henry's 1799 Elements of Experimental Chemistry. In particular, the book contains a very detailed description of the electric battery invented by Volta forty years earlier in 1800. The battery itself was constructed by Udagawa in 1831 and used in experiments, including medical ones, based on a belief that electricity could help cure illnesses.
