I mentioned this in my message in the Civil War discussion as a 
footnote but just in case anyone missed it -

LEWIS R. BINFORD (November 21, 1930 - April 11, 2011) passed away on 
Monday. He was, in my opinion, the most important thinker in 
archaeology between 1950 and 2011 and did more to change the 
discipline than what happened before 1965 or after 1980. It is not 
necessary to agree with his views to recognize his impact and contributions.

Again, I do not have the source at hand but there is an excellent 
interview with Binford by Mel Thurman in HISTORICAL ARCHAEOLOGY 
centered on his involvement with our field.
