Bartko, Frank (Allegheny Observatory)
Manuscripts
The collection deals primarily with the professional activities of Olin C. Wilson, who was most active from the mid-1930s into the 1980s. Wilson corresponded frequently with astronomers from a variety of universities in the United States and abroad, and the collection is representative of the deeply international and collaborative nature of astronomical and astrophysical research in the second half of the twentieth century. It also contains valuable and insightful material related to the schism between Mount Wilson and CalTech in the 1970s and 1980s, and the near-demise of Mount Wilson during that decade.

Stereographic photographs of the moon and two observatories
Manuscripts
A group of 12 stereoscopic photographs of the moon, and two stereoscopic photographs of observatories. The stereographs are on card mounts containing two images, which, when viewed through a stereoscope, produce a 3D image. The stereographs were produced by various photographers and publishers, including: "Anthony's Stereoscopic Views," made by E. & H. T. Anthony and Co.; John P. Soule; Joseph Ward; C. Bierstadt (from negatives taken by Prof. H. Draper); Bierstadt Bros. (from negatives by L. M. Rutherford. Taken 1864.); Joseph L. Bates; and H. C. Smith. There is an image of an observatory in Cambridge, Massachusetts, and another showing two men with telescopes outside an observatory in Northfield, Minnesota.
