Deutero-Isaiah

 

The theory that the Old Testament Book of Isaiah was written by two different authors and that chapters 1-39 were written by one author 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.
