Slides of Moon Photographs

Astronomy

Accession Number: 2018.ast.97

Description:

These are a set of eighteen large glass slides showing images of the lunar surface (16) taken through a telescope and photographs of the photographers (2). This is a set of eight 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).

They are kept in a stack inside a cardboard plate box that has two red and white stickers affixed in order to identify the contents.

Primary Materials: Glass, Cardboard

Markings:

Handwritten on the box over the original label: “J. N. L. Clark [?]
Finished Plate”

Written on the red and white stickers: “Photographie Lunaire
Plates 25-36.”

Dimensions (cm):

Length = 17.9, Width = 13.8, Height = 3.1

Function:

These slides were likely produced and used for demonstration or teaching purposes.

Condition:

Very Good: The majority of slides are in good condition, although they are slightly chipped around the edges, and some of the images are peeling towards the edge. Two of the slides, have been broken, one in half. The one broken in half has been crudely stuck back together with black fabric tape.

The box is intact, but very worn, particularly around the edges and on the corners.

Provenance:

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.
