George N. Saegmuller

George N. Saegmuller (1847-1934) was an instrument maker in the Washington, D.C. area. He is best known at the Naval Observatory for manufacturing the mounting of the 12-inch refractor, which stands atop its main building today. The mounting had been completed in November, 1892, but because the 12-inch lens was not yet completed, the old 9.6-inch refractor was mounted first. On December 19, 1895 the 9.6-inch objective was replaced with the 12-inch lens, with a focal length of 15 feet. The 12-inch refractor with Saegmuller's mounting is used today by numerous visitors on the popular Monday night tours. Gift of Saegmuller Family
