William Morris Davis


William Morris Davis (February 12, 1850 – February 5, 1934) was an American geographer, geologist, and meteorologist, considered by many to be the father of American geography

Davis was born into a Quaker family in Philadelphia, the son of Edward M. Davis and Maria Mott Davis. His father was a businessman who was expelled from the Society of Friends (Quakers) when he sided with the Northern Union in the American Civil War. His mother also subsequently left the Society of Friends.

He studied natural sciences at Harvard University and received his Master of Engineering in 1870. He then worked for three years in Cordoba, Argentina, as an assistant at the national meteorological observatory. In 1873 he returned to Harvard to pursue further studies in geology and physical geography. He received an appointment at Harvard as an assistant to geologist Nathaniel Southgate Shaler. He was given special responsibility for carrying out fieldwork activities. Shaler placed great importance on careful field observation, and he paid close attention to processes of change in the interpretation of variations at the Earth”s surface. Davis further developed these principles in his scientific work. In 1878, Davis received an appointment as an instructor of geology.

At the invitation of Raphael Pumpelly, who also taught geology at Harvard, Davis conducted research in Montana on the coal resources present. During this work, the ideas for a theoretical model to better interpret the genesis of landscape forms emerged. This model later became known as the erosion cycle. In 1885, his appointment as an assistant professor followed by a professorial appointment in 1890. In 1899 he was appointed as Sturgis Hooper Professor of Geology at Harvard, this chair he occupied until his retirement in 1912. During the period 1909-1912 he taught for a considerable time in Berlin and in Paris. After his retirement he continued to hold temporary appointments at the universities of Oregon, California and Arizona, among others.

Davis played an important role in the professionalization of American geography. He co-founded Association of American Geographers in 1904 and he also served as President of the Geological Society of America.

He did not hold a doctorate, but received numerous honorary doctorates

He died shortly before his 84th birthday in 1934 in Pasadena

In the 19th century, natural scientists searched for a useful concept by which the complexity of landscape forms could be described and interpreted. Davis was fascinated by Charles Darwin”s concept of evolution and found the basic principles of Darwin”s theory of great importance for studying landscape genesis. To describe landscape genesis, Davis resorted to the developmental progression of an organism. He described the stages of development of a landscape in terms of youth, maturity, and old age. In 1899 he published ´The Geographical cycle´ in which the basic principles of the erosion cycle were set out. For him, landscape forms were a function of the interaction between structure, process and time. The structure related to the geological structure of the area and the process concept stood for all forms of erosion. Using the erosion cycle, Davis described how rivers grind narrow V-shaped valleys in a ´young´ uplifted landmass. As they progress, these valleys deepen and widen to create a ´ripe´ hilly landscape. As the erosion process continues even further, the landscape flattens out to a peninsular plain. Davis clearly indicated that his model referred to an ideal sequence of landscape forms and that variations were possible according to place and circumstances. He gave numerous examples of this variation himself.

In numerous lectures, including outside the United States, Davis demonstrated and defended his views on landscape genesis. The influence of this model on geomorphology was so great for decades that it functioned as a paradigm for the practice of this science until about 1940.

At the invitation of Albrecht Penck, Davis gave a number of lectures on the erosion cycle in 1908. These lectures were translated by Alfred Rühl under the title “Die erklärende Beschreibung der Landformen” (Leipzig, 1912). Davis” ideas met with much resistance in Germany among others Alfred Hettner and Siegfried Passarge. The deductive model of the erosion cycle did not fit in with Hettner”s chorological views on the essence of geography, in which much attention was paid to the description of unique associations of phenomena in a given area. These unique associations could not be predicted on the basis of deduction, Hettner believed. The discussion was carried on in earnest also because there was much misunderstanding back and forth about definitions and assumptions used.

After 1950, there was increasing criticism of the theoretical foundations of the erosion cycle. Recent insights are based on the conviction that processes in geomorphological systems do not proceed linearly. There are too many coincidence factors so that for the same starting positions very different outcomes are conceivable. In contrast to the model with which Davis worked, more attention is now paid to the human factor in explaining landscape formation. Moreover, nowadays a distinction is made between time-dependent and time-independent processes. In the latter the processes do not lead to morphological changes, but only contribute to the continuation of an equilibrium situation in the landscape system.

Davis was very concerned with improving the quality of geography education. He wanted to get rid of the one-sided focus on factual knowledge and the insufficient use of generalizable concepts. In his view, geography needed to be defined as a general earth science, in which generalizations about the relationship between inorganic and organic nature should be central.

Davis was an exceptionally gifted teacher and also a very demanding one. He trained a large number of geographers who became responsible for the further development of American geography at various universities in the United States. His students included Mark Jefferson, Isaiah Bowman, and Ellsworth Huntington, among others.

Davis realized that the development of American geography would be furthered by the establishment of a professional organization. Partly at his urging, the AAG (Association of American Geographers) was created in 1904 with Davis as its first president.

Numerous were the (international) field trips organized by him. In 1911 he organized the ”Liverpool-Rome Pilgrimage” for an international group of 32 people. In 1912 Davis taught for some time at the Sorbonne in Paris and he used this opportunity to organize the famous ”Transcontinental Excursion of the American Geographical Society”. Forty-three European geographers (from 13 different countries) participated in this grand excursion. They were accompanied on their journey through the United States by a large number of American geographers. The trip lasted almost two months. A special train had been made available for the occasion. This excursion was the start of years of intensive contacts between American and European geographers.
