Arthur Newell Strahler (February 20, – December 6, ) was a geoscience professor at Columbia University who in developed the Strahler Stream Order system for classifying streams according to the power of their tributaries.

Strahler was largely responsible for the shift from qualitative to quantitative geomorphology during the mid 20th century.

In the middle of the twentieth century, Strahler spearheaded the campaign to fundamentally change how geologists and physical geographers pursue the study of landforms, which is called geomorphology. He challenged geomorphologists to move away from the traditional qualitative and descriptive Davisian approach to landform studies (named for William Morris Davis) that had been developed in the late nineteenth century and which emphasizes the long-term evolution of landscapes. In its place, Strahler advocated a quantitative, dynamic, process-oriented approach to the study of landforms that relies on detailed field observation, numerical measurements of form and process, mathematical representations, statistical methods, and systems analysis. Strahler’s conception of geomorphology was widely adopted in the second half of the twentieth century, and it remained the foundation of geomorphic research and education into the early s.

Early Life and Education Strahler was born in Kolhapur, India, to parents who were Presbyterian missionaries. Back in the United States he went to school in the Chicago area before attending the College of Wooster in Ohio, where he met his future wife, Margaret (Marge) Strahler. At Wooster he majored in geology and became most interested in structural geology and geomorphology as taught by Charles B. Moke and Karl Ver Steeg, respectively. The study of landforms in the United States at that time was almost completely dominated by the qualitative, descriptive approach developed by the prominent Harvard University professor William Morris Davis. Davis’s deductive theory of landscape development, called the geographical cycle, considered landforms to be the result of geologic structure, landforming processes, and time, the latter of which w
