Date context
1745–1827
From Como to university research
Born in Como, Volta began much of his scientific work outside regular university institutions. He later taught experimental physics and worked in Pavia, investigating electricity, gases and measuring instruments. His research connected improved apparatus with explanations of physical effects.

The dispute over frog-leg experiments
Galvani associated contracting frog legs with electricity in the animal. Volta repeated and modified the experiments, emphasizing combinations of different metals and moist conductors. Their competing interpretations prompted further investigation and should not be reduced to a simple story of one side being wholly correct.

The pile of 1800
Volta stacked dissimilar metals with separators containing conducting liquid to produce the pile announced in 1800. Unlike a brief electrostatic discharge, the apparatus could supply sustained current through a circuit, changing the experiments available to investigators.
A power source for further experiments
The pile enabled investigations of current and its chemical effects and became a starting point for other electrical devices. Volta demonstrated his research in Paris in 1801. His invention should be distinguished from the later discoveries made by researchers using such power sources.
