Ball lightning kills Richmann,1753. Artwork of the German physicist Georg Wilhelm Richmann (left,1722-1753),of Saint Petersburg,Russia,being killed in his laboratory by ball lightning during a thunderstorm on 6 August 1753. The previous year,following Franklin's proposals to use metal rods to investigate lightning,several such experiments had been carried out,including one by Dalibard in France (May 1752) and Franklin's kite- flying experiment (June 1752). Several attempts to replicate these experiments proved fatal. Richmann rushed home during a thunderstorm to carry out the experiment,but the force of the lightning singed his clothes,blew open his shoes,knocked out his engineer Sokoloff (right),ripped the door off its hinges,and killed Richmann,leaving a red mark on his forehead.
