This year's Reith lecturer is distinguished Professor of American history, Dr Daniel J Boorstin, the twelfth Librarian of Congress. In his Reith lectures, entitled 'America and the World Experience', he explores how the USA developed into the superpower it is today. In this first lecture entitled 'The Birth of Exploration', Dr Boorstin explains why the desire to journey to new and undiscovered lands was important in the development of the United States of America. He considers the difference between a 'frontier' and 'the wilderness' for the first colonisers of the continent and explains how a community spirit of adventure made it all possible.
