What is the name of President Bartlet's personal secretary who dies in a car crash?

President Bartlet's personal secretary who dies in a car crash is Dolores Landingham. She is usually addressed as Mrs. Landingham and serves as Josiah Bartlet's secretary during the first two seasons of The West Wing.

Landingham has known Bartlet since he was a schoolboy because she worked for his father, the headmaster of his private school in New Hampshire. That long history gives her unusual freedom to challenge the President's decisions and serve as his moral conscience. She previously worked for Bartlet when he was governor of New Hampshire.

Her death occurs in the second-season episode “18th and Potomac.” While driving her new car back from the dealership so Bartlet can “kick the tires,” she is killed by a drunk driver. The tragedy leads directly into “Two Cathedrals,” in which Bartlet grieves, questions his faith, and reflects on her influence. Margaret, Annabeth Schott, and Deborah Fiderer are other West Wing staffers, but none is the secretary killed in this storyline.
