Brigid Tenenbaum

"For so long, Brigid Tenenbaum is selling ADAM for everyone, which I saw her, and it both, in front of my very own eyes, but then it was so illegal for the Grand Alliance that the Coalition of the Red Star is so addicted to it. Well, I can believe that if we save can Elizabeth, and liberate the Little Sisters from ADAM, maybe peace on Earth can be restored once more, if I have to do something dangerous against North Korea."

--Su Ji-Hoon, Saving Elizabeth

Dr. Brigid Tenenbaum is a geneticist who discovered ADAM and helped develop it into products for commercial sale. She is also the "mother" of the Little Sisters. She created them, and eventually came to care a great deal about their safety, calling them her "little ones," acting as a mother to them, and regretting her part in helping create them. The player is able to win her allegiance by saving the Little Sisters instead of harvesting them for ADAM.

Early Life
Tenenbaum grew up near the city of Minsk in Belarus. Her father was German, and she was raised in the Jewish faith. When she was sixteen years old, she became a prisoner at the Nazi concentration camp at Auschwitz, where she observed German doctors, including Josef Mengele, experimenting on prisoners. Occasionally, when the Germans made scientific errors, she would correct them, and discovered that she had a vocation for science. Eventually, the Germans put her to work assisting in their infamous medical experiments. Tenenbaum considered the German experiments to be useless. While the rest of her family was killed, she survived the concentration camp, likely due to her helpfulness to the doctors, which had earned her the nickname "Das Wunderkind" ("The Wonderchild").
