Scientist (Fallout 3)

A scientist is a person that uses the scientific method. Many scientists appear in the Fallout series including the Lone Wanderer's father, James, Madison Li, and Dr. Zimmer.

There is a wrecked highway south of Raven Rock with a truck on it. If the player approaches the truck, an explosion goes off inside the truck and the body of a scientist flies out the back, off the bridge. He is carrying a Big Book of Science. There is a chance that a piece of his corpse may stay on the bridge, allowing easier looting without running into the mirelurks under the highway.

Another scientist can be found outside Vault 87. This female scientist was probably killed by the huge amount of radiation which lingers outside the Vault entrance.

Broken Steel
With the Broken Steel add-on, several scientist (called Project Purity Scientist) are added to Project Purity's control chamber. In dialogue, they constantly complain about Scribe Bigsley and his scribes, claiming that they only make things more difficult.
