The discovery of helium

Helium was discovered by the French astronomer Pierre Jules Cesar Janssen during a total solar eclipse in Guntur, India, in 1868. The same spectral emission lines were noted by the English astronomer Norman Lockyer, also in 1868, who proposed the name "helium," after Helios, the Sun God of Greek mythology.

In 1895 Sir William Ramsay separated for the first time helium from air in laboratory; the same year this experiment was repeated independently by Per Theodor Cleve and Nils Langlet in Sweden.
