What is Dr. Allison Cameron's first name in House M.D.?

Dr. Allison Cameron's first name in House M.D. is Allison.

Jennifer Morrison played Allison Cameron, one of the original doctors recruited to Gregory House's diagnostic team. Cameron is an immunologist and is characterized by her strong empathy for patients, a trait that often contrasts with House's deliberately abrasive bedside manner.

The character's name is spelled “Allison” with two l’s in the first syllable and two l’s overall. That spelling matters because “Alison” is also a common variant, and the similarly named character Amber Volakis appears later in the series. Cameron's professional and personal relationships with House and the other fellows become recurring parts of the show's early storylines.

Cameron was one of the original three fellows alongside Eric Foreman and Robert Chase. Jennifer Morrison appeared as a regular cast member in the early seasons and continued to return to the character in later episodes.
