Johannes Gabriel Granö

Johannes Gabriel Granö (14 March 1882 – 23 February 1956) was a Finnish geographer, chiefly remembered as a professor of three universities and an explorer of Siberia and Mongolia. He is also noted for his pioneering studies on landscape geography, and his book Pure Geography. Granö was a professor in universities of Tartu, Helsinki, and Turku.

Granö studied in Helsinki University, starting 1900 in botany but changing his major subject to geography. His minor subjects were biology and geology. As a young student he spent his vacations in Siberia, where his father worked as the priest for the Finnish population in Omsk 1901–1913. Granö took notes of the environment and his first scientific publication, published 1905 in "Fennia" was about the Finnish colonies in Siberia.

Granö developed the concept of "pure geography" as the unique subject of geographical research. He created a working methodology to define and classify landscapes, not only based on geomorphology but also taking into account bodies of water, vegetation and human impact. As the research object of his "pure geography" he had human perception, which was unique in geography those days.

Granö published a lot of his works in German, and thus he was in his lifetime best known in German-speaking areas. Only during First World War he published something in French.
