Madalyn Murray O'Hair
Madalyn Murray O'Hair (1919 - 1995) was an activist, founder of American Atheists, and famous for her stern opposition to religion, who in 1960 filed and won a lawsuit (Murray v. Curlett) against the Baltimore City Public School System, claiming that it was unconstitutional for her son to study the Bible at school; this lawsuit, combined with another, would reach the Supreme Court and result in the banning of prayer and recitations of Bible verses in American public schools in June, 1963.
She, her son and granddaughter suddenly disappeared; The evidence that has been disclosed does not point to a single conclusion. One would think that the disappearance of a well-known family such as the Murray-O'Hairs would be front page news but the papers have been strangely silent. Where is the Murray-O'Hair family? Are they dead or alive? Why has there apparently been no investigation? 
"There is no God. There's no heaven. There's no hell. There are no angels. When you die, you go in the ground, the worms eat you." Madalyn Murray O'Hair. 
In 2001, her son, her granddaughter and Madalyn's dismembered bodies had been located on a ranch in Austin, Texas. David R Waters, a fellow atheist associate had been charged with the crime. 
O'Hair was born in Pittsburg, Pennsylvania on April 13, 1919, the daughter of John Irwin and Lena Scholle Mays. She grew up there and in Ohio, graduating high school in Rossford in 1937. Her parents were Presbyterians and attended church regularly, but it was apparently during her teen years that she became an atheist. In 1941 she had her first marriage to John Henry Roths; this marriage was separated due to World War II and the enlistments they made to the Marine Corps and Women's Army Corps. In 1945 she engaged in an affair with a married man while stationed in Italy; the result of which was a son, whom she named William J. Murray after the father; she had since divorced her husband and had taken up the name "Murray". By 1952 she had earned two degrees: a bachelors from Ashland University in Ohio, and a degree from the South Texas College of Law; she never, however, capitalized on her law degree by going before the Texas bar and becoming a lawyer. A relationship with boyfriend Michael Fiorillo resulted in another son, Jon Garth Murray, being born in 1954.
Her life was filled with pornography. Her house had figures of mating animals, and she would often describe her trips to X-rated theaters, stating with some delight that she was the only female in the building. As son William stated later:
When I was a young boy of ten or eleven years old she would come home and brag about spending the day in X-rated movie theaters in downtown Baltimore. She was proud of the fact she was the only woman in the movie house watching this filth. My mother’s whole life circulated around such things. She even wrote articles for Larry Flynt’s pornographic magazine, Hustler. My mother lived in spiritual death as Paul writes: "But she that liveth in pleasure is dead while she liveth." I Timothy 5:6
Debate with Dr. Walter Martin
Madalyn Murray O'Hair did particularly badly in her debate with Dr. Walter Martin. For example, when she claimed there were supposedly were contradictions in the Bible, Dr. Martin asked her to provide an example of one and Ms. O'Hair did not and could not offer even an alleged example of one. In addition, Ms. O'Hair did a poor job defending against the issue of atheism and mass murder.
