Object Details
- August Lingke & Co.
- Description
- This is a German theodolite, quite unlike those made in England or the United States. Albert Joseph Seligman (1859-1935) probably bought it in the late 1870s, when he studied mining engineering at Freiberg, and he probably donated it to the Rensselaer Polytechnic Institute, his alma mater, around 1899, when he obtained a seat on the New York Stock Exchange.
- The horizontal circle is beveled, silvered, graduated to 20 minutes, and read by opposite verniers to single minutes. The vertical circle is silvered, graduated to 20 minutes, and read by opposite verniers to single minutes. The inscription reads "AUGUST LINGKE & CO FREIBERG IN SA NO 4265."
