University of Minnesota law librarians can expect a busy few months analyzing the biggest collection of letters to and from the famous lawyer Clarence Darrow. Darrow was involved in important cases like the Scopes trial back in 1925. That is when Darrow defended John Scopes, a teacher accused of breaking state law in Tennessee by teaching evolution to his students. For decades, the letters were tucked away with other Darrow family possessions. Minneapolis attorney Randy Tietjen discovered the letters more than ten years ago. He spoke with Morning Edition host Cathy Wurzer.
