Born in Freudental, Württemberg, on December 16, 1861, he studied natural sciences in Stuttgart and Tübingen and earned his doctorate in 1885. He later built a varied career as a zoologist, entomologist, and museum specialist, publishing scientific work while also gaining a reputation as a skilled keeper and observer of animals.
A major part of his life was spent in what was then German East Africa, where he worked at the Biological-Agricultural Institute in Amani. There he carried out zoological and applied research, especially on insects, linking field science with practical agricultural concerns.
In his later years he became director of the Zoological Garden in Hamburg. Sources describe him as both a productive researcher and an able zoo professional, and note his success in keeping difficult animals alive in captivity for unusually long periods. He died in Hamburg on September 18, 1933.
