Helium was discovered in 1868 as a new spectral line in light

from the sun by French astronomer Jules Janssen during a total

solar eclipse in Guntur, India. In the same year, Norman Lockyer,

an English Astronomer concluded that the new spectral line was

caused by an element in the Sun unknown on Earth and named it


In 1882, Italian physicist Luigi Palmieri detected helium on

Earth for the first time.

March 26, 1895 Sir William Ramsay, a Scottish chemist, isolated

helium on Earth.
