William Huggins was born at Cornhill, Middlesex, in 1824. In 1875, he married Margaret Lindsay, daughter of John Murray of Dublin, who also had an interest in astronomy and scientific research.[2]
She encouraged her husband's photography and helped to put their research on a systematic footing.[citation needed]
Huggins built a private observatory at 90 Upper Tulse Hill, London, from where he and his wife carried out extensive observations of the spectral emission lines and absorption lines of various celestial objects.[citation needed]
On 29 August 1864, Huggins was the first to take the spectrum of a planetary nebula when he analysed NGC 6543.[3][4]
He was also the first to distinguish between nebulae and galaxies by showing that some (like the Orion Nebula) had pure emission spectra characteristic of gas, while others like the Andromeda Galaxy had the spectral characteristics of stars.[citation needed]
Huggins was assisted in the analysis of spectra by his neighbor, the chemist William Allen Miller. Huggins was also the first to adopt dry plate photography in imaging astronomical objects.[2]
With observations of Sirius showing a redshift in 1868, Huggins hypothesized that a radial velocity of the star could be computed.[5]
Huggins won the Gold Medal of the Royal Astronomical Society in 1867, jointly with William Allen Miller. He later served as President of the Royal Astronomical Society from 1876 to 1878, and received the Gold Medal again (this time alone) in 1885. He served as an officer of the Royal Astronomical Society for a total of 37 years, more than any other person.[6]
Huggins was elected a Fellow of the Royal Society in June 1865, was awarded their Royal Medal (1866), Rumford Medal (1880) and Copley Medal (1898) and delivered their Bakerian Lecture in 1885.
He then served as President of the Royal Society from 1900 to 1905. For example, his Presidential Address in 1904 praised the fallen Fellows and distributed the prizes of that year.[7]
He died at his home in Tulse Hill, London, after an operation for a hernia in 1910 and was buried at Golders Green Crematorium.
In 1856 Huggins acquired a 5-inch diameter aperture telescope by Dollond.[8][9] In 1858 an 8-inch telescope by Clark was added.[9][8] These were both refracting telescopes.[9] They had glass objectives.
In 1871 Huggins acquired an 18-inch (0.46 m) speculum reflecting telescope from the Grubb Telescope Company.[10][9]
