- William Barlow
William Barlow (
August 8 ,1845 –February 28 ,1934 ) was an English amateurgeologist specializing incrystallography .He was born in
Islington , inLondon, 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 asspace groups . Unfortunately his results were published in 1894, only after they had been independently announced byYevgraf Fyodorov andArthur Schönflies , although his approach did display some novelty. His structural models of simple compounds such as NaCl and CsCl were later confirmed usingX-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
