Discovered: Pierre Janssen first obtained evidence of the existence of helium during the solar eclipse of 1868 when he detected an unknown yellow line in the solar spectrum signature. Norman Lockyer and Edward Frankland later confirmed his observations and named the new element helium from the Greek word 'helios', meaning the sun. William Ramsay was first to isolate helium on Earth in 1895 by treating the uranium mineral cleveite with mineral acids.
