Allison Cameron

Allison Cameron was a major character on House for the first six seasons. She was a member of Gregory House's diagnostic team during the first three seasons in the position of a fellow in Diagnostic Medicine. She was qualified as a specialist in immunology. She was the youngest member of House's original diagnostic team and the only female member. After Cameron left House's diagnostic team, she returned in the season four premiere as the senior emergency room attending physician at Princeton-Plainsboro Teaching Hospital. At the end of Season 5, she married Robert Chase. However, in Season 6, Cameron leaves PPTH, House and Chase. She guest-starred once in the Season 6 episode Lockdown, where she returns to ask Chase to sign the divorce papers and finally settles the outstanding issues in their relationship. She is seen in the series finale Everybody Dies both as a hallucination telling House that it's okay for him to die to end his pain, and in real life at House's funeral.

She was portrayed by Jennifer Morrison.

Early Life
Very little is known about Cameron's early life, but it is implied that unlike Foreman and Chase, her adolescence was rather uneventful. She was born in about 1979 in the area of Chicago, Illinois. Both of her parents are still living, and there has also been a reference to an older brother in the episode Fetal Position. However, the details of her family life are not known. She did admit that she was arrested at the age of 17 for an undisclosed reason.

It is not known where Cameron attended university. During her time there, she earned an A in Calculus, but when she realized her professor had made a grading error, she disclosed it and her grade was lowered.

Shortly after she finished university, she married her first husband even though she knew he had been recently diagnosed with terminal thyroid cancer. The husband died within six months of the marriage, but Cameron did take the precaution of freezing some of his semen.

We also do not know where she attended medical school (although Johns Hopkins Medical School was ruled out in Pilot). However, she did finish near the top of her class. She did her internship at the Mayo Clinic, a substantial accomplishment. She then completed a residency in immunology, but it has never been revealed where she did her residency.
