Alessandro Volta's theory of contact tension considered that the emf, which drives the electric current through a circuit containing a voltaic cell, occurs at the contact between the two metals. Volta did not consider the electrolyte, which was typically brine in his experiments, to be significant.

The wire was supposed to be suspended at 15 degrees, but a last minute change made for an even steeper challenge.
