Tim Berners-Lee


Sir Tim Berners-Lee invented the World Wide Web in 1989.

He is the co-founder and CTO of, a tech start-up which uses, promotes and helps develop the open source Solid platform. Solid aims to give people control and agency over their data, questioning many assumptions about how the web has to work. Solid technically is a new level of standard at the web layer, which adds things never put into the original spec, such as global single sign-on, universal access control, and a universal data API so that any app can store data in any storage place. Socially Solid is a movement away from much of the issues with the current WWW, and toward a world in which users are in control, and empowered by large amounts of data, private, shared, and public.

Sir Tim is the Founder, Emeritus Director, and an Honorary Member of the Board of Directors of the World Wide Web Consortium (W3C), a Web standards organization that he founded in 1994 which develops interoperable technologies (specifications, guidelines, software, and tools) to lead the Web to its full potential. He is a Director of the World Wide Web Foundation which was launched in 2009 to coordinate efforts to further the potential of the Web to benefit humanity.

A graduate of Oxford University, Sir Tim invented the Web while at CERN, the European Particle Physics Laboratory, in 1989. He wrote the first web client and server in 1990. His specifications of URIs, HTTP and HTML were refined as Web technology spread.

He is the Emeritus 3Com Founders Professor of Engineering in the School of Engineering with a joint appointment in the Department of Electrical Engineering and Computer Science at the Laboratory for Computer Science and Artificial Intelligence ( CSAIL) at the Massachusetts Institute of Technology (MIT) where he founded the Decentralized Information Group (DIG).

The Decentralized Information Group, works on the Solid Project to give people control of their own data and to re-decentralize the Web. He is the co-founder and CTO of inrupt, the company launched to ensure the success of the Solid platform and its open source community, and to build the ecosystem that supports it.

He is also a Professor in the Computer Science Department at the University of Oxford, UK. He is President of and founded the Open Data Institute in London. He is President of London's Open Data Institute.

In 2001 he became a Fellow of the Royal Society. He has been the recipient of several international awards including the Japan Prize, the Prince of Asturias Foundation Prize, the Millennium Technology Prize and Germany's Die Quadriga award. In 2004 he was knighted by H.M. Queen Elizabeth and in 2007 he was awarded the Order of Merit. In 2009 he was elected a foreign associate of the National Academy of Sciences. He is the author of "Weaving the Web".

On March 18 2013, Sir Tim, along with Vinton Cerf, Robert Kahn, Louis Pouzin and Marc Andreesen, was awarded the Queen Elizabeth Prize for Engineering for "ground-breaking innovation in engineering that has been of global benefit to humanity."

Sir Tim has promoted open government data globally and spends time fighting for rights such as net neutrality, privacy and the openness of the Web.

On 4 April 2017, Sir Tim was awarded the ACM A.M. Turing Prize for inventing the World Wide Web, the first web browser, and the fundamental protocols and algorithms allowing the Web to scale. The Turing Prize, called the "Nobel Prize of Computing" is considered one of the most prestigious awards in Computer Science. 

In September 2022, he won the Seoul Peace Prize for his work promoting data sovereignty and leading the movement to “decentralize” the web dominated by tech giants.

Speaking Engagements

I do a limited amount of speaking. If you have something you think I would be interested in speaking at, for academic events email with details of the event, projected audience size and profile, location and date.

My professional speaking is handled by Jana Padula at the Harry Walker Agency, (  (you may also cc Don Walker and please cc me as above).

Please use an email subject line with relevant information such as: : "Keynote in Milan, 23 Febrary 2100 at ISWC2100" including the date and place proposed.

AV Requirements

If I use slides (I often do not) I use a laptop -- currently a Mac running OSX. I do not need audio from the laptop.

Press: requesting interviews and materials

If you need a photo for publication, please complete the W3C photo request form. You do not need an account to complete the form, but an email address is required.

Alternatively, you can ask:

If you need an interview for an article, please check the

first, then please use email rather than phone. Please contact the general PR request line at W3C, rather than Amy van der Hiel (my assistant) or my Chief of Staff ( or Coralie Mercier (Head of Communications at W3C) to set up interviews with me or with other W3C staff.
