Two sons of the 19th century actor Junius Brutus Booth impacted history in vastly different ways. John Wilkes Booth aspired to be a success, but instead assassinated a great American President. Older brother Edwin followed in his father's footsteps and went on to become the greatest actor in 19th century America. This hour, we hear from historian Nora Titone, a native of Iowa City. Her first book is "My Thoughts Be Bloody: the Bitter Rivalry Between Edwin and John Wilkes Booth that Led to an American Tragedy." (Free Press)
