Bildnummer 11598313
| Benjamin Franklin,scientist,inventor,and US Founding Father (January 17 1706 - April 17 1790). Steel engraving by J. Thompson 1834 with later colouring,after 1778 painting by Duplessis. Dubbed "the First American" he may thus also be considered the first American scientist. His studies of electricity earned him the Royal Society Copeley Medal in 1753 and in 1756 he was elected Fellow of the Royal Society. After an honorary doctorate from Oxford in 1762 he became "Doctor Franklin". He helped demonstrate the unity of electrical phenomenon,and the existence of positive and negative charge. His celebrated kite flying in storms was designed to show that lightning was electrical. Being struck would be lethal,so he only suggested collecting charge to show that it performed in the same way as laboratory electrical charge. Among his many inventions is the first lightning rod and bifocals | |
