Alexander_Stewart_Herschel

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. He also worked on identifying comets as the source of meteor showers. The Herschel graph, the smallest non-Hamiltonian polyhedral graph, is named after Herschel due to his pioneering work on Hamilton's Icosian game.
