Slides of Moon Photographs


This is a set of thirteen large glass slides depicting images of the moon. Each 12cm x 16.5cm slide appears to be a copy of a page of a photographic atlas called “Photographie Lunaire” by Maurice Loewy and Pierre Puiseux (1910). Many of the slides have a red and white sticker stuck to one corner; this has a number in the corner. These range from 25 to 33.

The slides are contained in a cardboard box that originally held unexposed glass slides.

It is unknown when these slides were produced, or why. They may be associated with teaching at the Department of Astronomy, or with work done at the David Dunlap Observatory. If the latter, they were likely moved from the David Dunlap Observatory in Richmond Hill in 2008, upon the sale of the observatory. It was stored at the Department of Astronomy and Astrophysics until 2017, when it was moved to a new storage location in McLennan Physical Laboratories.
