Eidograph

An eidograph is an brass instrument for copying, reducing and enlarging illustrations. This example was made around 1860, probably by Alexander Adie & Son, scientific instrument makers based in Edinburgh.

30" copying eidograph in brass with brass-cased lead-weighted base, lead counter weight and fitted case, signed by Adie and Son, Edinburgh, c. 1860

The eidograph was an improved version of the simple pantograph which was invented in 1821 by William Wallace, Professor of Mathematics at Edinburgh University.
