Alexander Stewart Herschel, DCL, FRS (5 February 1836 – 18 June 1907) was a British astronomer.
Although much less well known than his grandfather William Herschel or his father John Herschel, he did pioneering work in meteor spectroscopy.Шаблон:SfnШаблон:Sfn He also worked on identifying comets as the source of meteor showers.Шаблон:Sfn The Herschel graph, the smallest non-Hamiltonian polyhedral graph, is named after Herschel due to his pioneering work on Hamilton's Icosian game.
Early life and education
The second son and fifth child of Sir John and Lady Margaret Herschel's twelve children,Шаблон:SfnШаблон:Sfn Herschel was born on 5 February 1836 at Feldhausen, near Cape Town, South Africa, where they had been since 1834 for John's astronomical work. His older brother was Sir William Herschel, 2nd Baronet, and his younger brother John Herschel the Younger was born in 1837.Шаблон:Sfn The family left for England on 11 March 1838, returning a few weeks before Queen Victoria's coronation.Шаблон:Sfn
After some private education, Alexander was sent to Clapham Grammar School in London in 1851, of which Charles Pritchard, who would later become Savilian Professor of Astronomy, was headmaster.Шаблон:Sfn In 1855, he proceeded to Trinity College, Cambridge, where he graduated B.A. as twentieth wrangler in 1859, proceeding M.A. in 1877.Шаблон:Sfn While an undergraduate he helped James Clerk Maxwell with his illustrations of the mechanics of rotation by means of the apparatus known as "the devil on two sticks."Шаблон:Sfn From Cambridge Herschel passed in 1861 to the Royal School of Mines in London, and began the observation of meteors which he continued to the end of his life.Шаблон:SfnШаблон:Sfn He early wrote, chiefly on meteorological subjects, papers for the British Meteorological Society, and between 1863 and 1867, he contributed many articles to the Intellectual Observer.Шаблон:Sfn
Career
From 1866 to 1871, Herschel was lecturer on natural philosophy, and professor of mechanical and experimental physics in the Andersonian University of Glasgow.Шаблон:Sfn From 1871 to 1886, he was the first professor of physics and experimental philosophy in the University of Durham College of Science, Newcastle upon Tyne.Шаблон:Sfn At the Durham College, Herschel provided, chiefly by his personal exertions, apparatuses for the newly installed laboratory, some being made by his own hands. When the college migrated as Armstrong College to new buildings, the new Herschel Physical Laboratory was named after him.Шаблон:Sfn
Herschel made accurate records of his observations of shooting stars in a long series of manuscript notebooks. He also accomplished important work in the summation, reduction, and discussion of the results of other observers with whom he corresponded in all parts of the world. With Robert P. Greg he formed extensive catalogues of the radiant points of meteor streams, the more important of these being published in the Reports of the British Association for 1868, 1872, and 1874. A table of the radiant points of comets computed by Herschel alone is in the Report for 1875. He was reporter to the committee of the British Association on the 'observations of luminous meteors,' and from 1862 to 1881 drew up annually complete reports of the large meteors observed, and of the progress of meteoric science. For the British Association (1874–81) he prepared reports of a committee, consisting of himself, his colleague at Newcastle, George A. Lebour, and John T. Dunn, which was formed to determine the thermal conductivities of certain rocks. For the Monthly Notices of the Royal Astronomical Society, he prepared the annual reports on meteoric astronomy each February from 1872 to 1880 and contributed many other important papers to the Notices.Шаблон:Sfn In a June 1872 paper, he showed the connection between meteors (the Andromedids) and comets (Biela's Comet), and he predicted the shower which recurred on 27 November of that year.Шаблон:Sfn Herschel acquired great precision in noting the paths of meteors among the stars. From his determination of the radiant point of the November Leonids, Giovanni Schiaparelli deduced the identity of their orbit with that of Tempel's Comet of 1866, 55P/Tempel–Tuttle.Шаблон:SfnШаблон:Sfn In 1864 and 1873 he observed the bright green colour of two respective Geminid meteors.Шаблон:Sfn
Besides meteoric astronomy, Herschel was interested in many branches of physical science, and became a member of the Physical Society of London in 1889 and of the Society of Arts in 1892. He contributed frequently to Nature, an article on "The Matter of Space" in 1883 being specially noteworthy. He worked much at photography, and in 1893 the Amateur Photographic Association presented an enlarged carbon print portrait of Alexander Herschel to the South Kensington Museum for the British Museum Portrait Gallery.Шаблон:Sfn
Herschel became fellow of the Royal Astronomical Society in 1867,Шаблон:Sfn and on 12 June 1884 was elected Fellow of the Royal Society, an honour already conferred on his grandfather, his father, and his younger brother John. In 1886, he gave up his professorship, and was made Doctor of Civil Law of Durham University.[1] In 1888, with other members of his family, he reoccupied the house in Slough, now called Observatory House, where his grandfather, Sir William Herschel, had lived. Here he resided until his death, absorbed in study, but late in life he made a journey to Spain to observe the solar eclipse of 1905.Шаблон:Sfn
Death
He died unmarried at Observatory House on 18 June 1907[1]Шаблон:Sfn and was buried in Church of St Laurence, Upton-cum-Chalvey, in the chancel of which his grandfather lies.Шаблон:Sfn
