Abstract

ArgumentOne of the first high-altitude observatories was a hotel. Established in 1823, the chalet on Mount Faulhorn became a highpoint of nineteenth-century science. In this paper, I take this mountain as my entry point into the examination of the special attraction that mountains exerted on scientists. I argue that Mount Faulhorn stood for three different conceptions of the usefulness of the mountain in science: (1) in observation networks, stations were usually chosen for pragmatic rather than scientific reasons, but mountains representedsingularspots in such networks, which deserved special attention; (2) the mountain also was amicrocosmwhere altitude differences were thought to capture essential features of latitude differences; (3) the mountain was sometimes no more than amacro-toolfor the pursuit of science, just a middle ground between the heaven and the earth.
