The Philip Fox papers, comprising one box, include correspondence, astronomical notes and calculations, notes and drafts of publications, and lists compiled by Fox of outstanding scientists.
The general correspondence covers the years from 1904 to 1941. Of interest are the four letters written in 1909 urging the purchase of the Simon Newcomb Library for the Astronomy Department at Northwestern. The standard equinox correspondence records Fox's interest in 1915 in establishing such a standard internationally.
In 1923 there occurred a traditional “class fight” between the freshman and sophomore classes at Northwestern. Members of each class attempted to carry off students from the rival class. In the course of one such episode, a high speed automobile chase through Evanston and Wilmette ended tragically with the death of Louis Aubere, who had been riding on the running board of one of the cars. Fox was a member of the committee of which investigated the incident. His detailed notes, three reports, and a chart of the events are included in the papers.
Also included are miscellaneous astronomical notes and calculations, unrelated to specific publications, followed by notes and drafts of several papers on flocculi (cloudlike shapes of calcium, hydrogen, or other elements, revealed in the solar atmosphere by the spectroheliograph).
Fox's publications (1911 to 1928) are listed in reports he sent to the president of Northwestern from 1922 to 1928. A few articles and offprints of publications by Fox are included in the papers, followed by the minutes of the 19th meeting of the American Astronomical Society in 1916, when Fox served as secretary.
The major publication of Fox, aside from volumes one through three of the Annals of the Dearborn Observatory, is the Rotation of the Sun (1921) which is found both as a rough draft and as a galley. Also included is his Paper on the Rotation of the Sun. The Catalogue of Stellar Parallaxes was compiled in the spring of 1939. The biographies of scientists were written by Fox in 1940, perhaps as a result of his investigations in connection with compiling a list of great scientists.
The remainder of the files consist of lists of astronomers, physicists, and other scientists. The correspondence which accompanies the lists of great astronomers was compiled for the Planetarium, and the list of physicists, astronomers, chemists, and mathematicians, was compiled for the Museum of Science and Industry.
The addition is comprised of thirty-six postcards, to and from Fox or the Dearborn Observatory. Each postcard carries a picture of an astronomical observatory. The addition has been incorporated into the Philip Fox Papers as Folder 22 of Box 1.
