who experimented with him, discovered electrical fire, and invented an electrical machine for producing the electrical spark. Franklin discovered what is now known as “positive” and “negative” electricity. He also attempted to explain, in his letters to Collinson, thunder and lightning as phenomena of electricity; and, in 1759, sent him a paper announcing his invention of the lightning-rod, and an explanation of its purpose and action. He also suggested an experiment that would prove that lightning was a form of electricity; and to show that lightning was attracted by points he proposed that a man should stand on a tall steeple, or tower, with a pointed rod and draw electricity from the thunder-clouds. The experiment was tried in France and England, and Franklin was proclaimed the discoverer of the identity of lightning with electricity. Some of the scientists used a tall metal rod. Franklin now thought of the kite experiment, because there were no steeples in Philadelphia tall enough.
