Huggins, Sir William

(1824-1910) Astronomer. Pioneer in astronomical photography, spectroscopy, and spectrum analysis, did noted research on the chemical stellar composition, discovered spectroscopically that luminous gas composed the irregular and planetary nebulae, proved that cometary light was mainly derived from incandescent carbonic vapors, made the first investigation with a spectroscope of a temporary star, and proved the presence of calcium in the chromosphere and solar prominences.
