Who She Was
Léonie Watson is a British web accessibility expert, technologist, and advocate who has spent her career working to ensure that the web is built in ways that work for everyone, including the estimated one billion people worldwide who live with some form of disability. Watson lost most of her sight in her twenties due to diabetes and became a screen reader user, giving her direct personal experience of the barriers that poorly built websites create for people who cannot see a screen. She has served on the W3C Web Accessibility Initiative, contributed to the development of international web accessibility standards, and co-chaired the W3C Web Platform Working Group, which shapes the technical specifications that define how browsers work. She is a sought-after speaker, educator, and advisor who has worked with governments, major corporations, and development teams around the world to make accessibility a standard part of how the web is built, not an afterthought. Her work sits at the intersection of technical expertise and lived experience in a way that few other figures in the field can match.
Why She Matters
Léonie Watson's career demonstrates something that the web development industry has been slow to learn: that building for accessibility is not a specialized niche but a fundamental responsibility of anyone who builds for the web. When a website cannot be navigated by a screen reader, or a form cannot be completed without a mouse, or a video has no captions, real people are excluded from information, services, and opportunities that everyone else takes for granted. Watson has spent her career making that exclusion visible and giving developers the tools and knowledge to fix it. Her influence on web standards means that the accessibility features built into every modern browser carry her fingerprints, whether the developers using them know it or not.
