Frederick Sanger won the Nobel Prize twice for his advances in chemistry. He influenced the treatment of disease and the understanding of RNA and DNA. The interests of Sangers fellow inventors in this period are diverse, ranging from the roller coaster design by Ron Toomer to animal cloning by Ian Wilmut. Computers and their potential were a major focus of the time. This volume ends with the work of Sergey Brin, co-creator of the search engine Google. Readers interested in technology will be enthralled by the biographies of these inventors and descriptions of their greatest creations.
