You can use COM interop to access the Word object model. This link talks about the technique: http://www.blog.pythonlibrary.org/2010/07/16/python-and-microsoft-office-using-pywin32/
The secret when working with any of the office objects is knowing what item to access from the overwhelming amount of methods and properties. In this case each document has a list of BuiltInDocumentProperties . The property of interest is "Last Author".
After you open the document you will access the author with something like word.ActiveDocument.BuiltInDocumentProperties("Last Author")
