Subseries 6. Frank Schlesinger, 1899-1920, 1907

Scope and Content Notes: Frank Schlesinger was Director from 1905-1920. Originally from Yerkes Observatory in Williams Bay, Wisconsin, Schlesinger was also president of the American Astronomical Society. His main research interest was the improvement of parallax measurements, a method of determining the distances to stars. The results of his investigations are world-renowned and he was considered an authority in that area of research. On the afternoon of Wednesday, August 28, 1912, the new observatory (Mr. Billquist was the chief architect) was dedicated and presented to the University of Pittsburgh. In the fall of 1907 Mrs. Christopher Lyman Magee donated funds to the Observatory for the purpose of establishing a publication for the research conducted by the Observatory which had been scattered throughout a variety of scientific periodicals. The first volume of the Allegheny Observatory came out in 1912 under the editorship of Frank Schlesinger. In 1920 Schlesinger left to assume the directorship of Yale Observatory.
