Named in memory of Carl Bosch (1874-1940), outstanding German chemist, inventor of high-pressure ammonia synthesis, 1931 Nobel laureate in chemistry and enthusiastic amateur astronomer. During the 1920s he built a well-equipped private observatory on his estate at Heidelberg, where he carried out spectroscopic and photometric studies. He was an important patron of science, supporting especially the Heidelberg-Königstuhl Observatory, the Astronomische Gesellschaft and the Einstein Foundation. Name proposed by the first discoverer, endorsed by G. Klare and H. Mandel.
