From what I've read about her ,plus the odd documentary, she was 'prickly' at best and could be quite obnoxious. She was also smart and tenacious. A great combination, an advantage for the powerless speaking to power.

Madalyn may not have been a nice woman , but in my opinion, this was a great woman .In America, a country deeply infected with religion, her task was probably harder than getting Miranda rights.

Sadly, Madalyn had a sad and sordid end, being murdered for gain------

From Wikipedia (a pretty good article actually) .

"--------------------Ultimately, the investigation focused on David Roland Waters, an ex-felon with a violent history, who had worked for American Atheists. He had pled guilty earlier that year to stealing $54,000 from the organization.[28] Shortly after his theft was discovered, O'Hair had published an article in the American Atheists newsletter exposing the theft and previous crimes.[13] O'Hair claimed that, at age 17, Waters had killed another teenager. Waters had been sentenced to prison for eight years.[13][28]-------- Waters was arrested and prosecuted; in a plea agreement to the charge of conspiracy, he agreed to lead authorities to the site where the dismembered bodies of the O'Hairs had been burned and buried. He was sentenced to serve 20 years in federal prison, which he had requested, rather than serve time in Texas state prison on his earlier theft conviction. He did not go to trial for the kidnapping and murders of the O'Hair. Source: The San Antonio Express-News articles on Jan. 30, 2001 and March 31. 2001. He was also ordered to pay back a total of $543,665 to the United Secularists of America and to the estates of Madalyn Murray O'Hair, Jon Garth Murray, and Robin Murray O'Hair. It is unlikely that these debts were paid, because Waters had no ability to earn money while in prison. Waters died of lung cancer on January 27, 2003 at the Federal Medical Center in Butner, North Carolina.[1"
