This is Franklin’s earliest recorded suggestion of the lightning rod. In the experiments
of points” he placed electrical charge on isolated conductors and then showed that the
charge could be drained away (discharged) slowly and silently if a pointed and
grounded (attached to ground) conductor were introduced into the vicinity. When the
pointed conductor was brought too close to the charged conductor, the discharge
occurred violently via an electric spark.

In the discussion in which he proposed the original experiment to determine if lightning
were electrical (July 1750—see Chapter 1), Franklin repeated his suggestion for
protective lightning rods, adding that they should be grounded (i.e., that a wire should
connect the lightning rod to the ground or, in the case of a ship, to the water).

Lightning rods were apparently first used for protective purposes in 1752 in France and
later the same year in the United States (Refs. 2.1, 2.2).

Franklin originally thought — erroneously — that the lightning rod silently discharged
the electric charge in a thundercloud and thereby prevented lightning. However, in 1755
he stated: I have mentioned in several of my letters, and except once, always in the
alternative, viz., that pointed rods erected on buildings, and communicating with the
moist earth, would either prevent a stroke, or, if not prevented, would conduct it, so that
the building should suffer no damage. (Ref. 2.3)

It is in the latter manner that lightning rods actually work.
