Brigid Tenenbaum

Brigid Tenenbaum is a brilliant but morally ambiguous Irish-American geneticist who played a pivotal role in the discovery and research of ADAM, a substance that grants superhuman abilities. Her experiments led to the creation of the Little Sisters, orphaned girls repurposed to gather ADAM from corpses. Throughout BioShock 2, she grapples with the consequences of her actions and aims to rectify the harm she caused. Highly intelligent, guilt-ridden, pessimistic, yet caring and determined to make amends, Tenenbaum helps the protagonist, Subject Delta, navigate the underwater city of Rapture and oppose the game's antagonist, Sophia Lamb, providing crucial information and resources to aid in their mission. She previously worked as a researcher at Columbia University and enjoys classical music and gardening but dislikes bureaucracy and dishonesty.
