In 1809, Humphry Davy invented the very first electric light. He did this by connecting two wires to a single battery and then attatching a charcoal strip between the other two ends of the wires. The charged carbon then glowed, making the very first arc lamp. He later invented the minerâs safety lamp in 1815.
Strontium metal was first isolated in 1808 by Sir Humphry Davy working in London using electrolysis. Davy had built a very large 600-plate battery, which he used to pass electricity through salts, breaking them down in order to isolate new elements. He mixed magnesium oxide to a paste with (probably) strontium sulfate.
