2. Benjamin Franklin
Benjamin Franklin (January 17, – April 17, 1790) was one of the Founding Fathers of the United States. A renowned polymath, Franklin was a leading author, printer, political theorist, politician, freemason, postmaster, scientist, inventor, civic activist, statesman, and diplomat.

3. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove.

4. Inventions and scientific inquiries
In 1750, he published a proposal for an experiment to prove that lightning is electricity by flying a kite in a storm that appeared capable of becoming a lightning storm. On May 10, 1752, Thomas-François Dalibard of France conducted Franklin's experiment using a 40-foot-tall (12 m) iron rod instead of a kite, and he extracted electrical sparks from a cloud.

5. On June 15 Franklin may possibly have conducted his well known kite experiment in Philadelphia, successfully extracting sparks from a cloud. Franklin's experiment was not written up with credit until Joseph Priestley's 1767 History and Present Status of Electricity.

6. Franklin was careful to stand on an insulator, keeping dry under a roof to avoid the danger of electric shock. Others, such as Prof. Georg Wilhelm Richmann in Russia, were indeed electrocuted during the months following Franklin's experiment.

7. End of the life
Benjamin Franklin died from pleuritic attack at his home in Philadelphia on April 17, 1790, at age 84. Approximately 20,000 people attended his funeral.
