"ADAM improved every aspect of Man - except his character."
A German woman who discovered a love for science at the age of sixteen, Bridgette Tenenbaum is a scientist who specializes in genetics. She performed genetic experiments on prisoners in German prison camps before coming to Rapture. She discovers the existence of a sea slug that can regenerate cells, which leads to the the creation of ADAM and the Little Sisters. She comes to serve as the Little Sisters' "mother", as she feels guilty for what she has done to the little girls.
