An attempt to replicate the experiment killed Georg Wilhelm Richmann in Saint Petersburg in August 1753; he was thought to be the victim of ball lightning. [4] Franklin himself is said to have conducted the experiment in June 1752, supposedly on the top of the spire on Christ Church in Philadelphia. However, the spire at Christ Church was not ...
Georg Wilhelm Richmann (Russian: Георг Вильгельм Рихман; 22 July [O.S. 11 July] 1711 – 6 August [O.S. 26 July] 1753) was a Russian physicist of Baltic German origin who did pioneering work on electricity, atmospheric electricity, and calorimetry. [1]
A 300-foot kite raised antenna increased their radio range from 60 or 70 miles to 110 miles. [7] The United States Navy conducted kite antenna experiments on the torpedo boats USS Stringham and USS Bailey in 1911. [8] Some Signal Corps units conducted kite antenna experiments independently, often constructing their own kites. In June 1907 the ...
The son of George II of Great Britain and father of George III died of a pulmonary embolism, but was commonly claimed to have been killed by being struck by a cricket ball. [20]: 105 [21] Professor Georg Wilhelm Richmann: 6 August 1753
The kite experiment was repeated by Romas, who drew from a metallic string sparks 9 feet (2.7 m) long, and by Cavallo, who made many important observations on atmospheric electricity. Lemonnier (1752) also reproduced Franklin's experiment with an aerial, but substituted the ground wire with some dust particles (testing attraction).
Franklin's experiment, in its initial conception, depended on the completion of Christ Church in Philadelphia, whose steeples would be sufficiently high as to attract a lightning strike. Franklin then conceived of an alternative experiment that involved flying a kite during a thunderstorm with a metal key attached to the string. [3]
Researchers have given their lives for this vision; Georg Wilhelm Richmann was killed by ball lightning (1753) when attempting to replicate the 1752 kite-flying experiment of Benjamin Franklin. [101] If an experiment cannot be repeated to produce the same
