Dr. Elizabeth Corday was a surgeon at County General Hospital in Chicago. She was portrayed by Alex Kingston from 1997 to 2004.

Early LifeEdit

Elizabeth is a British surgeon from England. Her father, Charles is a well-renowed surgeon at St. Thomas' Hospital in London and her grandfather was a surgeon as well. Elizabeth had somewhat of a rocky relationship with her mother, Isabelle. She feels that her mother didn't spend enough time with her as a girl, she feels that she was "raised by nannies and boarding schools", although Elizabeth finds a more nuanced perspective on things once she becomes a mother herself. Though Elizabeth and Isabelle do seem to come to some kind of mutual agreement, their relationship is still strained.

Season FourEdit


Elizabeth and Peter share a kiss.

Elizabeth moves from England to Chicago in order to gain more experience in trauma surgery. She faces many problems as she adjusts to the American way of life. In her first trauma, Elizabeth baffles the rest of the staff by using lots of British terms usually not used in America such as for example, she asks them to "bleep Benton" (or page Dr. Peter Benton), order an "FBC" (or a CBC), and perform a "tube thoracostomy" (or a chest tube). She also introduces herself as "Miss Corday", which is customary for British surgeons, and not "Dr Corday". She becomes popular amongst the other staff though, both for her surgical competence and for her personality.

Elizabeth becomes friends with many of the female ER staff such as Carol Hathaway and Anna Del Amico. She also becomes romantically involved with Peter Benton and they even share a kiss with each other. Near the end of the season, Elizabeth finds out that Dr. Romano wouldn't be renewing her sponsorship.

Even though the patient survives, Elizabeth has to face an inquiry. At the inquiry, she blames the system for the mistake comparing her hours to those of other jobs where people's lives are at risk. Meanwhile, Elizabeth attempts her relationship with Peter which eventually succeeds. After the incident with her patient, she ends her relationship with Peter for good.

When Dr. Maggie Doyle accuses Dr. Romano of sexual harrassment, Elizabeth wants to support her claims at first, but she's forced to back down when Dr. Romano reveals to her that he knew about Elizabeth's relationship with Peter while he was her supervisor.
