In 1751 Benjamin Franklin published “Experiments and Observations on Electricity, Made at Philadelphia in America.”
Experiments summarized in this booklet determined the existence of positive and negative charges, and the difference between insulators and conductors. This work led to the invention of the lightning rod. Its complete construction was popularized in Poor Richard’s Almanack in 1753. This is the first practical engineering application of electricity.
A unifying theory covering static electricity, lightning, and stored charge was invented.
