Benjamin Franklin performed his experiment on atmospheric
electricity on May 10, 1752. In the actual experiment he stayed under a shed
to protect himself from the rain. He had almost decided that the experiment
was a failure when he noticed that the fibers of the kite-string were standing
up. When he presented his knuckles to a metallic key attached to the end of
the string, he received a strong spark. After receiving other sparks, he
charged a Leiden jar with the electric fluid from the cloud.
Fortunately for bifocaled readers of the Saturday
Evening Post who received their copy in the mail, he did not kill himself.
The experimenter Georg Wilhelm Richmann of St. Petersburg was killed in the
following year doing the experiment.
