Works[edit]
Ritter's masterwork, the 19-volume Die Erdkunde im Verhältniss zur Natur und zur Geschichte des Menschen (Geography in Relation to Nature and the History of Mankind), written 1816–1859, developed at prodigious length the theme of the influence of the physical environment on human activity. It is an encyclopedia of geographical lore. Ritter unfolded and established the treatment of geography as a study and a science. His treatment was endorsed and adopted by all geographers.
The first volume of Die Erdkunde was completed in Berlin in 1816, and a part of it was published in the following year. The whole of the first volume did not appear until 1832, and the following volumes were issued from the press in rapid succession. Die Erdkunde was left incomplete at the time of Ritter's death, covering only Asia and Africa.
Many of Ritter's writings were printed in the Monatsberichte of the Berlin Geographical Society, and in the Zeitschrift für allgemeine Erdkunde. His Geschichte der Erdkunde und der Entdeckungen (1861), Allgemeine Erdkunde (1862), and Europa (1863) were published posthumously. Some of his works have been translated into English by W. L. Gage: Comparative Geography (1865), and The Comparative Geography of Palestine and the Sinaitic Peninsula (1866).
