On March 11, 1890, American engineer, inventor and science administrator Vannevar Bush was born. He is best known as as head of the U.S. Office of Scientific Research and Development (OSRD) during World War II, through which almost all wartime military research and development was carried out, including initiation of the Manhattan Project. In computer science we know Vannevar Bush as the father of the memex, an adjustable microfilm viewer with a structure analogous to that of the World Wide Web.
On November 13, 1990, one day after Tim Berners-Lee's and Robert Cailliau's publication of the concept of a world wide hypertext system [2], the first web page was published. Today, living without the World Wide Web, or simply the Web, has become almost impossible. Our daily live depends on news spread over the web and ecommerce hase become a convenient commodity. Nobody wants to live without it. Incredible, but only 20 years ago, most people lived in the stoneage compared to today's virtual online worlds.
