Late biographer Edmund Morris serves up a stirring final act with "Edison"
A monumental new biography of Thomas Edison is set to be released this week. The author is one of the greatest non-fiction writers of our time, Edmund Morris, who died this May at the age of 78, just after the book was finished. "Edison", a colossal work of research and writing, is a raw and unflinching look at a man whose inventions have shaped nearly every aspect of modern life. Jeff Glor reports.
