Niggli was born in [[Zofingen]] and studied at the [[ETH Zurich|Swiss Federal Institute of Technology]] in [[Zurich]] and the [[University of Zurich]], where he obtained a doctorate. In 1920 he became the lead scientist at the ''Institut für Mineralogie und Petrographie'', and brought a systematic approach to the study of crystal morphologies using X-rays, originating the system of 230 [[space group]]s. He retired from the Institute in 1949. He was also professor of mineralogy at the Eidgenössische Technische Hochschule and at the University of Zurich. The great aim of his life was to integrate the whole field of [[Earth science]]s. In 1948, Niggli was awarded the [[Roebling Medal]] of the [[Mineralogical Society of America]]. The Paul Niggli Foundation awards medals to outstanding Swiss mineral scientists below the age of 35 with a strong perspective for an academic career. [[Dorsum Niggli]] on the [[Moon]] was named after him. ==References== *{{Citation |id = [[PMID]]:13095398 |url= http://www.ncbi.nlm.nih.gov/pubmed/13095398 |last=LAVES |first=F |publication-date=1953 May |year=[[1953]] |title=[In memoriam: Paul Niggii, 26.
