Emission spectra of helium.
Sir Joseph Norman Lockyer
English Astronomer
Chromosphere of a solar eclipse. Lockyer discovered helium while observing an eclipse.

Contribution to the Development of the Atomic Concept
Sir J. Norman Lockyer discovered and named helium in 1869 while observing a solar eclipse using a spectroscope.  He knew that he had discovered a new element because the spectral lines did not match up with other known elements. This was the first time that an element was discovered in space before it was identified on earth.
