I just read an article via Friendly Atheist about a true American hero by the name of Ellery Schempp. As a high school student in Pennsylvania during the 1950s, Mr. Schempp felt that the daily bible reading he was forced to participate in was against his constitutional rights. You can read his personal account of how he successfully sued his school district thus bringing an end to daily bible reading in U.S. public schools. Details of the Supreme Court case can be read at Wikipedia.
