The theodolite was developed in the 18th century to provide very accurate location of points in space, an essential tool for surveying and mapping. Wikipedia has a comprehensive article on theodolites history and use. This model is based on the David Whites Instrument Company’s LT 8300 model, probably made in the late 1930s by the company in Milwaukee, WI, USA.
