Senior Scribe Ritter was a Senior Scribe of an unnamed chapter of the Brotherhood of Steel.
Senior Scribe Ritter was killed around the same time that Elder Raymond Lorn was known to not like him very much. Lorn's base was under attack during the incident and he claims the death was a case of friendly fire. A report of the incident was written up by Head Scribe Bucek.
Ritter is mentioned only in Fallout: New Vegas.
