Who were the pioneers in two opposite school of thoughts of environmental determinism and possibilism??
Alfred Hettner, a German Geographer known for his concept of chorology (the study of places and regions) is most widely considered as one of the pioneers of school of thought of Possibilism. However, even earlier than him, a French geographer Paul Vidal de la Blache , became the first active advocate of possibilism. Some other advocates were Jean Brunches, Isaiah Bowman and Carl Sauer. French historian Lucien Febvre was the first who coined the term possibilism and contrasted it with environmental determinism.
