About MeThe Eidograph was invented sometime about 1831 by William Wallace of Edinburgh. Wallace was a mathematician, born in Dysart in 1768. Similar to the pantograph the eidograph allows a draughtsman to copy drawings and plans to the same or different scales (enlarged or reduced). The Eidograph, although more complex than the pantograph is more stable hence given better accuracy. The maker of this model, Stanley made their first instruments in the 1860s and it continued to appear in the company's catalogues to the 1960s. This Eidograph was originally used in the Aberdeen firm Walker and Duncan, Chartered Engineers, Architects and Surveyor.
