Lewis Roberts Binford (November 21, 1931 – April 11, 2011) was an American archaeologist known for his influential work in archaeological theory, ethnoarchaeology and the Paleolithic period. He is widely considered among the most influential archaeologists of the later 20th century, and is credited with fundamentally changing the field with the introduction of processual archaeology (or the "New Archaeology") in the 1960s. Binford's influence was controversial, however, and most theoretical work in archaeology in the late 1980s and 1990s was explicitly construed as either a reaction to or in support of the processual paradigm. Recent appraisals have judged that his approach owed more to prior work in the 1940s and 50s than suggested by Binford's strong criticism of his predecessors. Source: Wikipedia (en)
