William Wallace's Chorograph (1839): A Rare Mathematical Instrument (2010)

unapi

In 1839, William Wallace, Edinburgh University's newly retired professor of mathematics, invented the chorograph, a mathematical instrument for use in cartography and navigation. This instrument, owned by a descendant of Wallace, has recently come to light. As it failed to replace the station pointer, no other copies are known to have survived. Its mode of operation and its merits and demerits are here described.
