Rudolf von Raumer

Rudolf von Raumer (14 April 1815, Breslau – 30 August 1876, Erlangen) was a German philologist and linguist, known for his extensive research of the German language. He was the son of geologist Karl Georg von Raumer.

Biography
He studied classical and Germanic philology at the universities of Erlangen and Göttingen, where his instructors were Friedrich Christoph Dahlmann and Jacob Grimm. From 1840, he was privatdocent at the University of Erlangen, where in 1846 he became an associate professor. In 1852, he became a full professor of German language and literature at Erlangen.

In 1870, he wrote his major work, volume 9 of a series entitled Geschichte der Wissenschaften in Deutschland, which was entitled Geschichte der Germanischen Philologie vorzugsweise in Deutschland. He is cited in Konrad Duden's Die deutsche Rechtschreibung in the preface as a significant influence for this writing.

In regards to historical and comparative phonology, Raumer understood the need for more specific phonetic concepts and vocabulary, and he proposed numerous refinements and clarifications in that area. He stressed the basic role of Jacob Grimm's work and the need to advance beyond it. He also conducted comprehensive research on German dialectology and orthography. In 1876, his ideas for spelling reform were partially carried out by the Prussian government.
