Project Purity scientist

s are scientists presumably hired from Rivet City by the Brotherhood of Steel to work on Project Purity in 2277.

Background
The Scientists are not affiliated with the Brotherhood, so how they came to work at the Jefferson Memorial is never explained.

Interactions with the player character
The Scientists work in the Rotunda, and are not very welcoming to the person who gave them all that work, similar to Bigsley.

Appearances
s appear in the Fallout 3 add-on Broken Steel.
