Wilhelm Joseph Grailich (16 February 1829, Pressburg – 13 September 1859, Vienna) was an Austrian physicist, mineralogist and crystallographer. From 1847 he studied sciences at the polytechnic institute in Vienna, later serving as an assistant to Andreas von Ettingshausen in the institute of physics at the University of Vienna. In 1856 he became an assistant at the ''Hofmineraliencabinett'', where soon afterwards, he succeeded Gustav Adolf Kenngott as "kustos-adjunkt". In 1857 he became an associate professor of higher physics at the university, and in 1859, was chosen as a member of the Vienna Academy of Sciences. He died in Vienna on 13 September 1859, at the age of 30.〔(Grailich, Wilhelm Joseph ) @ NDB/ADB Deutsche Biographie〕〔(ADB:Grailich, Joseph ) @ Allgemeine Deutsche Biographie〕 In 1910, a thoroughfare in the Landstrasse district of Vienna was named ''Grailichgasse'' in his honor.〔Statement based on translated text from an equivalent article at the German Wikipedia.〕 Known for his work in crystal optics and crystal physics, he was the author of numerous scientific papers in the field of crystallography. In 1856, he translated William Hallowes Miller's textbook of crystallography into German as "''Lehrbuch der Kristallographie''".〔 He explained the phenomenon of fluorescence in crystals,〔(The physical review ) by American Institute of Physics, American Physical Society, Cornell University〕 and is credited for making improvements to Wheatstone's vibration apparatus (in German: "''Schwingungsapparat''").〔 == Selected works == * ''Untersuchungen über den Ein- und Zweiaxigen Glimmer'', 1853 - Studies on uniaxial and biaxial mica. * ''Das Sklerometer, ein Apparat zur genaueren Messung der Harte der Krystalle'', 1854 - (with F Pekárek) - The sclerometer, an instrument for accurate measurement of the hardness of crystals. * ''Untersuchungen über die physikalische Verhältnisse krystallisirter Körper'', 1858 (with Viktor von Lang) - Studies on the physical conditions of crystallized bodies. * ''Der Römerit, ein neues Mineral aus dem Rammelsberge, nebst Bemerkungen über die Bleiglätte'', 1858 - Romerite, a new mineral from the Rammelsberg. * ''Krystallographisch-optische Untersuchungen'', 1858 - Crystallographic-optical studies.〔(Google Search ) (publications)〕〔(WorldCat Identities ) Most widely held works by J Grailich〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wilhelm Josef Grailich」の詳細全文を読む スポンサード リンク
