Task: Question Answering
Input (English): Passage: The story is about a lawsuit concerning injuries caused by a defective automobile. The suit takes on a personal dimension because the injured plaintiff's attorney, Jedediah Tucker Ward discovers that the automobile manufacturer's attorney is his estranged daughter Maggie Ward.
Jedediah Ward is a liberal civil rights lawyer who has based his career on helping people avoid being taken for a ride by the rich and powerful; he's pursued principle at the expense of profit, though he has a bad habit of not following up on his clients after their cases are settled.
Jed's daughter, Maggie, has had a bad relationship with her father ever since she discovered that he was cheating on her mother, Estelle, and while she also has made a career in law, she has taken a very different professional route by working for a high-powered corporate law firm and has adopted a self-interested political agenda.
Jed is hired to help field a lawsuit against a major auto manufacturer whose station wagons have a dangerous propensity to explode on impact while making a left turn, but while his research indicates he has an all but airtight case against them, the case becomes more complicated for him when he discovers that Maggie is representing the firm he's suing.
The auto manufacturer in the film also utilizes a "bean-counting" approach to risk management, whereby the projections of actuaries for probable deaths and injured car-owners is weighed against the cost of re-tooling and re-manufacturing the car without the defect (exploding gas tanks) with the resulting decision to keep the car as-is to positively benefit short term profitability. 
Question: What is the first name of the person who is discovered to have been cheating on their wife?
Output (English): Jed.
