- This telescopic level has a horizontal circle that is silvered, graduated to 20 minutes, and read by opposite verniers with magnifiers to single minutes. Albert Joseph Seligman (1859-1935) probably bought it in the late 1870s, when he studied mining engineering at Freiberg. 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. A German silver tag on the box reads "Albert J. Seligman New York." The inscription on the level reads "AUGUST LINGKE & CO FREIBERG IN SA NO 2000."
