“Who Was 'Shadow'?” the Computer Knows: Applying Grammar-Program Statistics in Content Analyses to Solve Mysteries About Authorship

Abstract

This study's objective was to employ the statistics-documentation portion of a word-processing program's grammar-check feature as a final, definitive, and objective tool for content analyses - used in tandem with qualitative analyses - to determine authorship. Investigators concluded there was significant evidence from both modalities to support their theory that Henry Watterson, long-time editor of the Louisville Courier- Journal, probably was the South's famed Civil War correspondent “Shadow” and to rule out another prime suspect, John H. Linebaugh of the Memphis Daily Appeal. Until now, this Civil War mystery has never been conclusively solved, puzzling historians specializing in Confederate journalism.
