Samuel Christian Hollmann, professor of philosophy and natural theology, was Haller’s friend and colleague at the University of Göttingen. Their surviving correspondence consists of fourteen letters by Hollmann and two letters and a fragment of another by Haller. Hollmann’s first three, from the years 1745–46, focus on Haller’s activity as book reviewer and journalist. The exchange grows more intense following Haller’s return to Bern in the spring of 1753 and his announcement that he had decided to accept a post there. That surprising decision and Haller’s subsequent change of mind is an urgent theme in several letters. The progress and ultimate failure of the journalist Christoph Mylius’s planned scientific expedition to America, for which Haller served as director, soon becomes the main subject until the end of the correspondence, in January 1755. The two men also devote a bit of space to their own activities and to news from the republic of letters.
