'''William Barlow''' ([[August 8]], [[1845]] – [[February 28]], [[1934]]) was an [[England|English]] amateur [[geologist]] specializing 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 labor 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]]. Unfortunately his results were published in [[1894]], only after they had been independently announced by [[Yevgraf Fyodorov]] and [[Arthur Schönflies]], although his approach did display some novelty. His structural models of simple compounds such as [[Sodium chloride|NaCl]] and [[Caesium chloride|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]]. ==Awards and honors== * Entered into the [[Royal Society]], 1908. * The [[wrinkle-ridge]] ''[[Dorsa Barlow]]'' on the [[Moon]] was named after him. {{DEFAULTSORT:Barlow, William}} [[Category:1845 births]] [[Category:1934 deaths]] [[Category:English geologists]] [[Category:Fellows of the Royal Society]] {{geologist-stub}}
