John Henry Reynolds (1874–1949) war ein britischer Astronom und von 1935 bis 1937 Präsident der Royal Astronomical Society. Sein Arbeitsgebiet war die Klassifikation von Sternen.[1][2][3]

John Reynolds war der Sohn von Alfred John Reynolds, zeitweise Lord Mayor von Birmingham und Inhaber einer Firma, die Nägel in einem Schnittverfahren herstellte.[4][5] Als Amateur wurde er im Jahr 1899, im Alter von 25 zum Mitglied der Royal Astronomical Society gewählt. Im Jahr 1907 finanzierte er den Bau des 30-Zoll Spiegelteleskops in Helwan, Ägypten, dem ersten größeren Teleskop zur Studie des südlicheren Himmels. Er baute zudem eigenhändig ein 28-Zoll Teleskop in Birmingham.[6][7]

John Henry Reynolds (1874–1949) was a British astronomer who served as the president of the Royal Astronomical Society between 1935 and 1937 and is known for his work on the classification of stellar bodies.[1][2][3] An amateur, he was the son of Alfred John Reynolds, the Lord Mayor of Birmingham, who owned a company which cut nails.[4][5] In 1899, at age 25, he was elected a Fellow of the Royal Astronomical Society and in 1907, he financed the construction of a 30-inch reflecting telescope in Helwan, Egypt, the first large telescope to study objects in the such southerly skies. He also hand-constructed a 28-inch telescope in Harborne.[6][7] Images from the Reynolds telescope was later used by Gérard de Vaucouleurs in his system of classifying galaxies; Reynolds also published his own classification for spiral galaxies in 1920. Edwin Hubble frequently corresponded with Reynolds, and some of his findings into the classification of stellar bodies seems at least inspired by his work.[8] The Hubble–Reynolds law, a formula for measuring the surface brightness of elliptical galaxies, is named after them.
