Peirce and Astronomical Photography Aud Sissel Hoel Taking its point of departure from the current digitisation of the Harvard Astronomical Plate Collection, this article follows the plates back to the time when the status of photography as a research tool for astronomers was still to be established. It focuses on Charles S. Peirce, who, while employed by the US Coast Survey, made astronomical observations and contributed to the deliberation over visual and photographic methods. Particular attention is paid to Peirce’s involvement in early explorations of photography’s potential as a measurement tool.

First, photographic methods afford comparability across time and space; they transcend the limited scale of individual observers situated firmly in the here and now. Second, they involve a peculiar repeatability – peculiar because what they repeat is not strictly speaking ‘the same’: what today’s astronomers are able to see and detect by way of the plates is not the same as astronomers saw and detected at the time the astronomical views were taken. The latter characteristic connects with a third – namely, that the revealing powers of photographic methods transcend the intentions and uses envisioned by the people who devised the instruments and produced the photographs. Taking its point of departure from the current digitisation and use of the Harvard Astronomical Plate Collection, this article explores the problem of photography’s revealing powers by following the plates back to the time when the status of photography as a research tool for astronomers was yet to be established. In this context, the choice of the term ‘tool’ is no coincidence. What I hope to show is that approaching photo- graphy as a tool, rather than as a sign or representation, offers new inroads into the old problem of photography’s realism.
