R. (Rudolf) Bommeli

Born in Berg, Thurgau, on May 26, 1859, Rudolf Bommeli trained as a teacher and later studied natural science in Zurich under Arnold Dodel. Reference works describe him as the son of a modest artisan, and note that he remained unmarried.

From about 1890 onward, he published popular science books with the socialist publisher J. H. W. Dietz in Stuttgart. His materialist and socialist views reportedly made it hard for him to keep teaching posts, and he later lived in Geneva before settling in Stuttgart, where he worked as a writer and translator. He died in Zurich on July 31, 1926.

Bommeli is remembered less as an academic specialist than as a gifted popularizer of natural history. Works listed under his name show a strong interest in geology, prehistory, evolution, and the broader story of life on Earth, written for readers curious about science beyond the classroom.
