Jean-Claude Golvin is a French architect and archaeologist and former researcher of the French institution CNRS (Centre National de la Recherche Scientifique). He is THE specialist concerning archaeological reconstructions, of which he created over 1000 up until now and which are featured in numerous publications, exhibititions and lately computer games.
I just published a small blog post about Archaeological Reconstructions on the blog of Smarthistory. It is short, but covers the essentials of reconstruction. You can have a look here: http://smarthistoryblog.org/2015/12/15/archaeological-reconstructions-by-sebastian-hageneuer-m-a/
