Pinkerton

 is an inhabitant of Rivet City, mysterious and hard to find. He can give you facial reconstruction surgery, and is rumoured to have been one of the founders of Rivet City.

He lives in the broken bow of Rivet City, and can only be reached by swimming underwater, fighting your way through Mirelurks and his traps.

He will give you information in the The Replicated Man quest, telling you that he gave the android, Harkness, a new face and new memory so he could live a new life in Rivet City.
