Madelyne Murray O'Hair

Madelyne Murray O'Hair (1919-1995) was an American atheist activist and the founder of American Atheists, one of the nation's most prominent secular advocacy organizations. She achieved national prominence in 1963 when her legal challenge to mandatory school prayer in Baltimore public schools reached the U.S. Supreme Court. In the landmark decision Murray v. Curlett, the Court ruled that mandatory prayer in public schools violated the First Amendment, establishing a crucial precedent for church-state separation. O'Hair became a lightning rod for controversy, receiving both acclaim from secular advocates and intense criticism from religious conservatives. She was a fearless and outspoken advocate for atheism and separation of church and state during an era when such positions were deeply unpopular. O'Hair's activism transformed the American secular movement from a marginal position to an organized political force. She wrote extensively on atheism and secularism and established the precedent for modern secular activism in America. Her life ended tragically in 1995 when she was murdered in Texas.
