Franklin's electrostatic machine on display at the Franklin Institute. Franklin's electrostatic machine is a high-voltage static electricity-generating device used by Benjamin Franklin in the mid-18th century for research into electrical phenomena.
Experiments and Observations on Electricity is a treatise by Benjamin Franklin based on letters that he wrote to Peter Collinson, who communicated Franklin's ideas to the Royal Society. [ 1 ] [ 2 ] The letters were published as a book in England in 1751, and over the following years the book was reissued in four more editions containing ...
Franklin Hiram King (8 June 1848 – 4 August 1911) was an American agricultural scientist who was born on a farm near Whitewater, Wisconsin, attended country schools, and received his professional training first at Whitewater State Normal School, graduating in 1872, and then at Cornell University.

Benjamin Franklin pioneered the study of electricity by being the first to describe positive and negative charges, [61] as well as advancing the principle of conservation of charge. [62] Franklin is best known for the apocryphal feat of flying a kite in thunderstorm to prove that lightning is a form of electricity which, in turn, led to the ...
Benjamin Franklin Drawing Electricity from the Sky, an artistic rendition of Franklin's kite experiment painted by Benjamin West, c. 1816 The BEP engraved the vignette Franklin and Electricity (c. 1860) which was used on the $10 National Bank Note from the 1860s to 1890s.
In 1843, John Lawes and Joseph Henry Gilbert began a set of long-term field experiments in agronomy at Rothamsted Research Station in England; some of them are still running. [13] In 1905, Sir Albert Howard, studied agronomy and focused on organic agriculture processes. In 1943, Howard published his book on An Agriculture Testament. [3]
Franklin's observations aided later scientists [citation needed] such as Michael Faraday, Luigi Galvani, Alessandro Volta, André-Marie Ampère and Georg Simon Ohm, whose collective work provided the basis for modern electrical technology and for whom fundamental units of electrical measurement are named.
Based on these observations, Franklin developed the idea of the lightning rod. The lightning rod consists of a metal rod or conductor, typically made of copper or aluminum, that is mounted on the roof of a building and connected to the ground by means of a conductive wire.
