William Barlow FRS (8 August 1845 – 28 February 1934) was an English amateur geologist specialising in crystallography. He was born in Islington, in London, England. His father became wealthy as a speculative builder as well as a building surveyor, allowing William to have a private education. After his father died in 1875, William and his brother inherited this fortune, allowing him to pursue his interest in crystallography without a need to labour for a living. He served as the president of the English Mineralogical Society from 1915 until 1918. He died in Great Stanmore, Middlesex, England.

  • William Barlow FRS (8 August 1845 – 28 February 1934) was an English amateur geologist specialising in crystallography. He was born in Islington, in London, England. His father became wealthy as a speculative builder as well as a building surveyor, allowing William to have a private education. After his father died in 1875, William and his brother inherited this fortune, allowing him to pursue his interest in crystallography without a need to labour for a living. William examined the forms of crystalline structures, and deduced that there were only 230 forms of symmetrical crystal arrangements, known as space groups. His results were published in 1894, after they had been independently announced by Evgraf Fedorov and Arthur Schönflies, although his approach did display some novelty. His structural models of simple compounds such as NaCl and CsCl were later confirmed using X-ray crystallography. He served as the president of the English Mineralogical Society from 1915 until 1918. He died in Great Stanmore, Middlesex, England. (en)
  • William Barlow (* 8. August 1845 in Islington, London; † 28. Februar 1934 in Great Stanmore, Middlesex) war ein britischer Kristallograph, Geologe und Mineraloge. Barlow war der Sohn eines wohlhabenden Bauunternehmers und war zeit seines Lebens finanziell unabhängig, nachdem er 1875 beim Tod seines Vaters sein Erbe angetreten hatte. Er war anfangs selbst im Bauunternehmen seines Vaters tätig (die Wohnungen in Nord-London bauten), verfolgte aber nach Antritt seines Erbes wissenschaftliche Interessen, speziell in Mineralogie und Kristallographie. 1894 veröffentlichte er über die 230 Raumgruppen der Kristallographie. Er fand diese unabhängig von Arthur Moritz Schönflies und Jewgraf Stepanowitsch Fjodorow, veröffentlichte aber später (Schönflies und Fjodorow fanden sie um 1890). Barlow fand seine Ergebnisse aber ebenfalls schon früher. Seine erste Veröffentlichung dazu war von 1888. Dabei sagte er auch zwei Typen kubischer Kristallstruktur bei Mineralien vom Natriumchlorid-Struktur-Typ voraus, was durch Röntgenkristallographie später bestätigt wurde (Bragg 1913). Barlow verfolgte einen anderen, von seiner geometrischen Anschauung geprägten Zugang zur Klassifikation der Raumgruppen als Schönflies und Fjodorow, die eher mathematisch orientiert waren. 1915 bis 1918 war er Präsident der Mineralogical Society of Great Britain and Ireland. 1908 wurde er Fellow der Royal Society. Nach ihm sind die Dorsa Barlow auf dem Erdmond benannt. (de)

Seu pai enriqueceu especulando na construção de casas, possibilitando que William frequentasse escola particular. Após falecer em 1875, William e seu irmão herdaram sua fortuna, permitindo-o dedicar-se ao seu interesse em cristalografia sem a necessidade de trabalhar para sobreviver. Williem examinou as formas de estrutura cristalina, e deduziu que existiam somente 230 diferentes formas de simetria cristalina, conhecidas como grupos espaciais. Infelizmente seus resultados foram publicados em 1894, após terem sido anunciados independentemente por Evgraf Fedorov e Arthur Moritz Schoenflies, embora sua abordagem tenha mostrado novidades. Seus modelos estruturais de compostos simples, tais como NaCl e CsCl foram confirmados posteriormente mediante cristalografia de raios X. Foi presidente da Sociedade de Mineralogia Inglesa, de 1915 a 1918. Participou da 2ª Conferência de Solvay, em 1913, que teve como tema principal "A Estrutura da Matéria". (pt)
