Sir William Huggins (1824-1910) was an English astronomer best known for his pioneering work in astronomical spectroscopy. He built a private observatory in South London where he and his wife carried out extensive observations of the spectral emission lines and absorption lines of various celestial objects. He was the first to distinguish between nebulae and galaxies by showing that some had pure emission spectra charaterstics of gas, whilst others like the Andromeda Galaxy had spectra characteristics of stars. He was also the first to adopt dry plate photography in imaging astronomical objects. Between 1900 and 1905 he was president of the Royal Society.
