Editing Ball lightning (section)

=== Georg Richmann ===
A 1753 report recounts lethal ball lightning when professor [[Georg Richmann]] of [[Saint Petersburg]], Russia, constructed a kite-flying apparatus similar to [[Benjamin Franklin]]'s proposal a year earlier. Richmann was attending a meeting of the [[Russian Academy of Sciences|Academy of Sciences]] when he heard thunder and ran home with his engraver to capture the event for posterity. While the experiment was under way, ball lightning appeared, travelled down the string, struck Richmann's forehead and killed him. The ball had left a red spot on Richmann's forehead, his shoes were blown open, and his clothing was singed. His engraver was knocked unconscious. The door-frame of the room was split and the door was torn from its hinges.<ref>{{cite book |last= Clarke |first= Ronald W. |author-link= Ronald W.
