Is the Web a solo act or a duo?

Discover Robert Cailliau’s crucial role in its birth.

The Other Father of the Web

When we talk about the inception of the World Wide Web, Tim Berners-Lee naturally springs to mind. But nestled in the annals of web history is another key figure – Robert Cailliau. As a technology manager with a rich background in software development and Agile methodologies, I’ve always been captivated by the stories of pioneers like Cailliau, whose contributions have shaped our digital landscape.

A Partnership for Innovation

Cailliau, a Belgian computer scientist, played an instrumental role alongside Berners-Lee in the development of the web. In 1990, they jointly proposed a project to CERN that would lay the foundation for the web as we know it today. It was Cailliau’s advocacy and networking skills within CERN that helped garner the support necessary to get the project off the ground.

The Unsung Hero

Despite his crucial contributions, Cailliau often remains in Berners-Lee’s shadow. As a mentor to leaders and project managers, I see a powerful lesson in Cailliau’s story. It reminds us that success is often a collaborative effort, and the limelight doesn’t always shine on every contributor. In the world of software and web development, the collective effort is paramount.

Cailliau’s Legacy in Agile Development

Cailliau’s collaborative approach resonates deeply with Agile principles. In building development teams and implementing Lean software development strategies, I often reflect on how Cailliau’s teamwork and adaptability mirror Agile’s core values. His work serves as a reminder that open communication and collaboration are key to successful project outcomes.

From Vision to Reality

Robert Cailliau’s journey from a visionary idea to a tangible, world-changing technology exemplifies the power of digital transformation. His efforts in the early stages of the web’s development echo the challenges we face in modern IT governance, emphasising the importance of a clear vision backed by solid planning and execution, much like the principles found in COBIT and ITIL frameworks.

Inspiring Future Innovators

Cailliau’s story is not just a historical footnote; it’s a source of inspiration. As we mentor the next generation of software developers, project managers, and leaders, we underscore the importance of recognising every contributor’s efforts. In a field as dynamic as technology, every individual’s input can be the catalyst for groundbreaking innovation.

In Conclusion

Robert Cailliau may not be as widely recognized as Tim Berners-Lee, but his contributions to the web are invaluable. His story is a testament to the fact that behind every great innovation, there is often more than one visionary. As we navigate the ever-evolving world of technology, let’s remember to acknowledge and celebrate the collaborative spirit that drives progress and innovation.


As we continue to weave the digital tapestry initiated by pioneers like Cailliau and Berners-Lee, let’s embrace the principles of teamwork, innovation, and leadership they exemplified. The web’s creation wasn’t just about coding; it was about envisioning a connected world. And as we mentor, lead, and develop, we carry forward this legacy of collaboration and vision, one line of code at a time.
