Elizabeth Masen

"What others cannot do, this is what you must do for my Edward."

- Elizabeth Masen to Carlisle Cullen

Elizabeth Masen was Edward Cullen's biological mother and was married to Edward Masen Senior. Carlisle describes her in New Moon as having the same bronze hair and emerald green eyes that Edward had as a human. She lived in Chicago, Illinois.

Carlisle treated her when she and Edward were dying of the Spanish influenza in 1918. Elizabeth doted on her son, and Carlisle tells Bella Swan that she ruined her own chances of living by nursing Edward. While on her death bed in a hospital in Chicago, she said to Carlisle, "You must do everything in your power. What others cannot do, that is what you must do for my Edward." Carlisle still wonders to this day, if Elizabeth knew he was a vampire.

Edward inherited all of Elizabeth's jewelry at her death, and Edward gives Bella his mother's heart shaped diamond charm for her bracelet, along with proposing to Bella with Elizabeth's engagement ring in Eclipse. It is also mentioned that he has given jewelry to both Esme and Alice. The ring is described as a long oval, with slanted rows of diamonds, surrounded with gold netting.
