Charles Babbage
Charles Babbage (1791-1871) was a British mathematician. He came up with the idea of the computer in the 1830s. He called his machine the Analytical Engine but the technology back then wasn't good enough for him to actually build it. It took about a hundred years until the necessary technology was available to build it. Even though it was never completed, the Analytical Engine would have many of the basic elements of the present-day computer. -
Ada Lovelace
Ada Lovelace (1815-1852) was a mathematician. Charles Babbage was her associate and they worked together to develop his machine the "Difference Engine". Year 1843 she wrote an algorithm for the mechanical computer and predicted the possibilities of computers as problem solvers and to calculate formulas. So Ada Lovelace became the first computer programmer ever. -
Alan Turing
Alan Turing (1912-1954) was a mathematician and computer scientist. He invented the Turing machine. It was a hypothetical computing device. The machine is today considered to be one of the foundational models of computer science. He also developed a machine called the Bombe during World War II. It helped break the German Enigma code so he could read messages about the enemy military operations. Turing is by some considered the hero of World War II -
Douglas Engelbart
Douglas Engelbart (1925-2013) was an American inventor and engineer. He is mostly famous for inventing the computer mouse but he did many other things as well. He made many contributions to the computing industry. He had an own research laboratory where he worked on inventing and perfecting devices like the computer mouse and hypermedia (which is linking things such as text, audio, and images etc in one single document). He also improved different input devices. -
Bill Gates
Bill Gates is an american business man, software developer and investor. He is the co-founder of Microsoft which is the largest personal-computer software company in the world. It develops and sells computer software and other related services. Microsoft have developed Windows, PowerPoint, the communication application Skype and the video gaming brand Xbox. Gates is one of the people that has made it possible for people to use computers all the time. He is one of the richest people in the world. -
Steve Jobs
Steve Jobs is the co-founder of Apple.His first computer-related work was at Atari, which is where he met Steve Wozniak. They later created Apple together. Jobs left Apple in 1986 after feeling forced out of the company but returned again in 1996. He is one of the reasons to why revolutionary products such as the iPod, iPad and the iPhone, that are used by very many people, were created. -
Tim Bernes-Lee
Tim Berners-Lee is the creator of the WWW (short for the World Wide Web). WWW is system that makes websites and other files accessible via the Internet. Before WWW the Internet was almost only a text-based world. -
Larry Page
Larry Page is the co-founder of Google. He came up with the idea of a WWW search engine that is called PageRank. It is an algorithm that ranks web pages in Google search's engine results. It works by ranking links and finding out how important they are by counting how often they have been linked by other pages.
