Early Life

Tim Berners-Lee was born on June 8, 1955, in London, England. Both of his parents were mathematicians who worked on one of the first commercial computers, the Ferranti Mark 1, so technology was part of his life from the very beginning. As a child, Tim loved building things and was fascinated by electronics. He enjoyed playing with toy trains and learned about circuits by tinkering with a model railroad. His curiosity about how information could be connected and shared would eventually lead him to change the world.

Education and Early Career

Berners-Lee studied physics at Queen’s College, Oxford University, graduating in 1976. While at Oxford, he built his own computer using a soldering iron, an old television, and a processor he bought from spare parts. After college, he worked at several technology companies, learning more about computer networking and software. In 1980, he took a short job at CERN, a famous physics research laboratory in Geneva, Switzerland, where scientists from around the world needed to share their research. It was at CERN that he first had the idea of linking information together using something called hypertext.

Inventing the World Wide Web

In 1989, Berners-Lee wrote a proposal at CERN describing a new way for scientists to share information across computer networks. He created three key technologies that made the World Wide Web possible: HTML, the language used to create web pages; URLs, the addresses that locate pages on the Web; and HTTP, the set of rules computers use to send web pages to each other. By the end of 1990, he had built the first web browser, the first web server, and the first website. It is important to understand that the internet and the World Wide Web are not the same thing: the internet is the network of connected computers, while the Web is a system that runs on top of the internet to share information through linked pages.

Making the Web Free

One of the most important decisions Berners-Lee ever made was to give his invention away for free. He could have patented the World Wide Web and charged companies to use it, which might have made him one of the richest people in the world. Instead, he convinced CERN to release the Web technology so that anyone could use it without paying. This decision allowed the Web to grow incredibly fast, connecting billions of people by making information available to everyone. By 2022, there were more than five billion internet users around the world, all using the system he created and gave away.

Awards and Activism

Berners-Lee has received many honors for his world-changing invention. In 2004, Queen Elizabeth II knighted him, giving him the title Sir Tim Berners-Lee. He founded the World Wide Web Consortium, known as W3C, to set standards and guide the Web’s development. He has spent much of his career fighting to keep the internet open, affordable, and free from censorship, believing that access to information is a basic right. Berners-Lee continues to work on new projects to give people more control over their personal data and to make sure the Web remains a force for good in the world.
