Detroit Observatory
From Wikipedia, the free encyclopedia
The Detroit Observatory was built in 1854 at the University of Michigan in Ann Arbor, Michigan. It provided a number of astronomical tools for study, including a 6-inch (15 cm) Pistor & Martins meridian circle and a 12⅝-inch (32 cm) Henry Fitz, Jr. refracting telescope, which in their day were among the largest in the world.
In 2005, the Detroit Observatory became a division of the Bentley Historical Library.
