Tim Berners-Lee

Sir Tim Berners-Lee invented the World Wide Web in 1989 while working as a fellow at CERN, the European particle physics laboratory, and in doing so created the single piece of infrastructure that has done more than any other to define how humanity generates, shares and now trades in data. Every web page, browser cookie and online dataset traces its lineage back to the system he proposed in a modest memo titled 'Information Management: A Proposal'.

Educated in physics at The Queen's College, Oxford, Berners-Lee built the first web browser, server and the HTTP and HTML standards that still underpin the internet today. Crucially, he and CERN placed the technology in the public domain royalty-free in 1993, a decision widely credited with allowing the web to grow into an open, universal platform rather than a proprietary one. He founded the World Wide Web Consortium (W3C) at MIT in 1994 to steward technical standards, and was knighted by Queen Elizabeth II in 2004 for his services to the internet's development.

As the commercial internet matured into an economy built on harvesting and trading personal data, Berners-Lee became one of its most prominent internal critics. In 2009 he co-founded the World Wide Web Foundation to campaign for digital rights and an open web, and in 2018 launched the start-up Inrupt to commercialise Solid, a decentralised data-storage protocol he designed to let individuals control their own personal data pods rather than surrender them to platforms. The project represents a direct technical rebuttal to the surveillance-driven data model he has repeatedly warned threatens the web's original promise.

Berners-Lee has continued to use his standing to press governments and companies on digital rights, testifying to parliaments, publishing annual 'Contract for the Web' assessments, and warning against monopolistic control of data and AI. He received the ACM Turing Award, computing's highest honour, in 2016, and in 2025 published a memoir, 'This Is for Everyone', reflecting on the web's evolution and its unfinished promise.

Now based at Oxford, where he holds a professorial research fellowship, and continuing to chair W3C's Solid work alongside Inrupt, Berners-Lee remains the web's foremost conscience: the person best placed to say what the data economy was meant to be, and how far it has drifted from that original design.
