Judith Jarvis Thomson
Judith Jarvis Thomson (October 4, 1929 – November 20, 2020) was an American philosopher who studied and worked on ethics and metaphysics. Her work ranges across a variety of fields, but she is most known for her work regarding the thought experiment titled the trolley problem and her writings on abortion. She is credited with naming, developing, and initiating the extensive literature on the trolley problem first posed by Philippa Foot which has found a wide range use since. Thomson also published a paper titled "A Defense of Abortion", which makes the argument that the procedure is morally permissible even if it is assumed that a fetus is a person with a right to life.
