Anna Holt

 is a scientist working together with Doctor Li and Janice Kaplinski on portable fusion power and hydroponics experiments in 2277.

Background
Anna was responsible for the gestation of naturally occurring foodstuffs during her tenure in the Rivet City Science Lab, where she worked under Doctor Li. Soon kidnapped by the Enclave, Anna Holt was "forced" to help the Enclave in their experiments at Raven Rock. She was astonished by the technology the Enclave possessed and she quickly told them everything about Project Purity. Her current whereabouts are unknown, and she's presumed dead.

Quests

 * The Waters of Life: Holt is one of the scientists who relocated to Jefferson Memorial.
 * The American Dream: She can be found inside Raven Rock, now working for the Enclave. Killing her at this point, after she's turned traitor, will still grant negative Karma. Leaving her to be blown up along with Raven Rock will not, however.

Appearances
only appears in Fallout 3.
