Whose Code Created the World Wide Web?

In March 1989, British computer scientist Tim Berners-Lee submitted a proposal at CERN titled "Information Management: A Proposal," outlining a system for sharing research documents across the internet using hypertext. By December 1990, he had built the three foundational technologies: HTML (the markup language for web pages), HTTP (the communication protocol), and the URL system (web addresses). He also wrote the first web browser and the first web server, running on a NeXT computer at CERN. Berners-Lee made the technology freely available, declining to patent it, which allowed the web to grow explosively. He was knighted in 2004.
