Deutero-Isaiah

The theory that the Old Testament book of Isaiah was written by two different authors and that chatpers 1-39 were written by one authoer and 40-55 written by another.  The latter chapters would be designated as Deutero Isaiah. 

This theory, however, is incorrect.  Isaiah was written by a single author.
