To mark the 100th anniversary of Upton Sinclair's seminal work, The Jungle, Random House will publish Anthony Arthur's new biography of the writer, entitled Upton Sinclair: Radical Innocent. Sinclair's novel stands as one of the most important works in the literature of social change, a book so shocking that it launched a government investigation into the Chicago stockyards and its accompanying labor practices at the turn of the century. Random House will also be releasing an anniversary edition of The Jungle with a preface by Arthur and introduction by noted urban critic Jane Jacobs. Anthony Arthur has taught American literature at California State University, Northridge, and at various times during throughout his academic career he was a Fulbright scholar in Hungary, an exchange professor in Germany, and a visiting professor at the U. S. Air Force Academy. He is the author of four non-fiction books with St. Martin's Press and Thomas Dunne Books, and is a co-author of an American history reader.
