Walther Penck was born in Vienna as the son of German geographer Albrecht Penck.[3] He obtained a Ph.D. by studying petrology at Heidelberg University.[1] Between 1912 and 1915 he worked in Dirección General de Minas in Buenos Aires before moving to the University of Constantinople where he was named professor of mineralogy and geology. He finally settled as a professor in the University of Leipzig in 1918.[3] The areas he studied in detail and based his theories on include the Black Forest in Germany, Puna de Atacama in Argentina and Anatolia in modern Turkey.[1][5]
During the 1920s Penck, with Siegfried Passarge, Alfred Hettner and his father, was the foremost figure in a broad German opposition to the "geographical cycle" theory of William Morris Davis.[6] It was characteristic of Davis to react violently and disdainfully to criticism, particularly to this German criticism; it was also his characterictic to choose to attack the most vulnerable points of that criticism.[7] Regarding Walther Penck's objections to the Davisian geographic cycle Davis commented to Albrecht Penck in 1921:[8]
It is pleasant news that your son, Walther, is established as professor in Leipzig where his father long ago studied. As he may have told you, I have enjoyed reading parts of his Argentine monograph, an able piece of work, and I have written asking him to specify the difficulties he finds in accepting the cycle theory. I am inclined to believe that he really does not know what that theory is...
Walther Penck died of oral cancer in September 1923.[1] His book, Morphological Analysis of Landforms, was published posthumously in 1924 by his father as was also his paper Die Piedmontflächen des südlichen Schwarzwald (The piedmont-flats of the southern Black Forest).
