Series I. Correspondence of Directors/Acting Directors, 1850-1977

Subseries 1. Samuel Pierpoint Langley, 1850-1896, 1899

Scope and Content Notes:

Samuel Pierpoint Langley was born in Roxbury, MA, on August 22, 1834 and was Director of the observatory from 1867-1887. After graduating from the Boston Latin School, he studied civil engineering and architecture. His first employment was as an assistant in the Observatory at Harvard University; soon afterwards he became an instructor at the United States Naval Academy at Annapolis. In 1867 Langley became the Director of the Allegheny Observatory which had been transferred from private hands to the Western University of Pennsylvania; at the same time he was elected to the chair of Astronomy and Physics at the University.

Langley's main field of interest was the sun. He made detailed drawings of sunspots, invented the bolometer (an instrument to measure the amount of heat in different parts of the sun's spectrum), and obtained accurate time by using the telescope and positions of the stars. He also made accurate time available to Pittsburgh, City Hall, and to local railroads--even the U.S. Naval Observatory used his system (Allegheny System) to supply the correct time to the nation. During his term Mr. William Thaw contributed much money to the Observatory as did Andrew Carnegie who stated: "This was my first considerable gift to an institution of learning." Langley left to become first assistant secretary and then secretary to the Smithsonian Institute. He remained in that position until his death in 1906. Samuel Pierpont Langley died in Aiken, South Carolina, on February 26, 1906.

Subseries 4. John Alfred Brashear, 1866-1903

Scope and Content Notes:

John Alfred Brashear was Director Pro Tem from 1898-1900. Brashear was originally a mill worker, but, encouraged by his friend S.P. Langley and financially supported by William Thaw, he became a renowned lens-maker, setting up the Brashear Company which constructed both the 30-inch Thaw Memorial Telescope and the James E. Keeler Memorial Telescope. In 1867 Brashear raised matching funds from Thaw and Carnegie and he and Keeler drew up plans for a new observatory and equipment. In 1898, Keeler declared "The Observatory's usefulness is at an end" due to antiquated equipment, the encroachment of homes, factories, and the smoky, hazy atmosphere which obscured vision. Brashear spoke eloquently for aid in constructing a new "Temple of the Skies," but both the Panic of 1893 and the War of 1898 hampered the raising of funds. Discouraged, Keeler left for Lick Observatory at the University of California.

When Keeler died in 1906, his ashes were placed in the crypt of the memorial telescope built for him. Brashear persevered in his efforts to build a new observatory, eventually raising the $300,000 needed and securing a plot of land in Riverview Park. Appropriately, when the new observatory was dedicated in 1912, he was master of ceremonies (as he had been at the laying of the cornerstone in 1900). Upon their deaths, the ashes of both Brashear and his wife were also enclosed in the crypt (with Keeler's ashes) of the Keeler Memorial Telescope--the tablet bears the inscription "We have loved stars too fondly to be fearful of the night," words chosen by Brashear from "The Old Astronomer to His Pupil," a poem by Sarah William.

Subseries 5. F.L.O. Wadsworth, 1894-1905, 1907

Scope and Content Notes:

F.L.O. Wadsworth was Director from 1900-1905. It was during Wadsworth's directorship on October 20, 1900 that the cornerstone of the new building was laid. Modifying and adding to the plans he was mostly concerned with the supervision of the construction of the new buildings and instruments. He also exerted his influence, along with Brashear and the Observatory Committee, in raising the needed funds. The Observatory was completed in 1905, but the work of equipping it delayed dedication until 1912.

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.

Subseries 9. Nicholas E. Wagman, 1930-1970

Scope and Content Notes:

Nicholas Emory Wagman was Acting Director from 1941-1947, then Director from 1947-1970. Wagman became an astronomer at the Observatory in 1930 and became acting director in 1941 upon Dr. Jordan's death. In 1946 he announced one of the rarest finds of modern astronomy: a dark star in the constellation Ophiucus, which he named "Alpha Opiuchi C." As a result of this discovery, he was appointed Director in 1947. He investigated stellar and astrometric binaries and undertook a comprehensive program of modernization. He played a leading role in the disseminating of information on astronomy to the Pittsburgh public community. He served as lecturer at Buhl Planetarium and conducted forums at the YMCA. He was prominent as a member of the American Astronomical Society and the American Association for the Advancement of Science. He left the Allegheny Observatory in 1970.
