The Full Story
Helium was first isolated on Earth in 1895 by Scottish chemist William Ramsay in London. He obtained the gas while investigating cleveite, a uranium-bearing mineral, and found that its spectral lines matched the helium seen in the Sun. The work was a major milestone because it confirmed that helium existed naturally on Earth as well as in space. Ramsay went on to isolate several other noble gases, transforming the understanding of the periodic table.
