The genesis of the Wheatstone bridge

In the paper in the Philosophical Transactions of the Royal Society in which Wheatstone described the DC bridge that now bears his name, he attributes the idea of the bridge to S.H. Christie. French and German translations published the following year and possibly prepared from a preprint of the paper do not carry this attribution and this may explain why the bridge does not bear Christie´s name. This paper discusses the work of both Christie and Wheatstone and why the term Wheatstone bridge and not Christie bridge is used
