Yorkshire road contractor Percy Shaw developed his 'cat's eye' reflector device in the 1930s - a simple but critical innovation that soon spread all over the world. This attractively illustrated book explores many such inventions that have shaped human progress and characterize modern civilization. Covering a range of fields it traces, for example, innovation in communication from the quill pen to global positioning systems, and progress in medicine from the invention of spectacles in the 13th century to genetic engineering.
