Mary Goodman was a scientist working at the Cambridge Polymer Labs.
Background
Mary and the other scientists at the lab were locked inside the labs by Jon Elwood when the bombs fell. Aiming to finish the Nucleostrictive Lining Project so that they could leave, Mary, Tom Franklin, and Ericka Elwood-Woolum tried to gather U-238 samples from the lab's Isotope Containment chamber. However, she was locked inside by Wilfred Bergman, dooming both her and the other researchers, who couldn't access the materials needed to finish their work, to succumb to radiation from the leaking reactor.[1][2][3]
Notes
Despite Mary being the only one locked inside the containment chamber, both a glowing one and a skeleton can be found inside the room.
Appearances
Mary Goodman is mentioned only in Fallout 4.
