Sextants and accessories
Description
An account of the resource
The "old astronomy" was dominated by the precise measurement of the positions of the stars and the determination of time. At Illinois, astronomy was first taught as part of the Civil Engineering department helping to develop the engineers' surveying skills. Specialized telescopes and procedures were developed for this purpose. As the "new astronomy" of astrophysics began to develop, positional astronomy was taught less and less. The one exception was the need for navigation by military ships and airplanes. In 1918 a Navigation course was offered for air service men. The course continued after WWI and was advertised as a course of interest to engineers and those thinking of working on merchant ships. This collection consists of sextants and other accessories such as artificial horizons that were used in positional astronomy, surveying, and navigation.

Description
An account of the resource
The Willis Pendulum Astrolabe was used primarily by the armed forces to determine latitudes and longitudes. The astrolabe is stored in a large green wooden box. It is marked “PENDULUM ASTROLABE David White Co. Milwaukee Wisc USA, No. 65649, M-5107, 1952, U.S.” The instrument was invented by John Willis> The advantage of the Willis pendulum was that it used a mirror instead of mercury as a reflecting surface. It was able to measure position on earth to within 20 feet. The David White Company was founded in 1895 and continues to provide precision optical tools used in surveying.
