The proposal for funding that secured the early development of the World Wide Web originated from a collaboration between Robert Cailliau and Tim Berners-Lee. A Belgian computer scientist, Cailliau navigated the technical landscape of CERN for over three decades, fundamentally shaping the transition of hypertext systems from internal documentation tools into a global public resource.
Early Education and Military Service
Born in Tongeren in 1947, Cailliau moved to Antwerp in 1958. He completed his undergraduate studies at Ghent University in 1969, earning a degree as a civil, mechanical, and electrical engineer. He subsequently attended the University of Michigan, obtaining an MSc in Computer, Information and Control Engineering in 1972. During his mandatory service in the Belgian Army, he applied his technical skills by maintaining Fortran programs used to simulate troop movements.

Cailliau joined CERN in December 1974 as a fellow within the Proton Synchrotron division, where he focused on control system renovations. By 1987, he became group leader for Office Computing Systems. When Tim Berners-Lee introduced his hypertext proposal in 1989, Cailliau became a primary advocate for the project. He co-authored funding requests and managed student teams to develop web browsers for UNIX and Classic Mac OS, including the MacWWW browser created with Nicola Pellow.
Public Domain and Global Expansion
Collaboration with CERN's legal team culminated on 30 April 1993, when Walter Hoogland signed the document placing web technology into the public domain. Cailliau organized the inaugural International World Wide Web Conference at CERN in 1994, which gathered 380 participants and established the International World Wide Web Conferences Steering Committee. He also initiated the WISE project with the Fraunhofer-Gesellschaft and the Web for Schools project for the European Commission.
Later Career and Recognition
Cailliau facilitated the handover of web development responsibilities to the World Wide Web Consortium. Following his retirement from CERN in 2007, he engaged in pan-European political movements, including the Newropeans organization. He holds the status of External Collaborator at CERN IdeaSquare. His career has been marked by numerous accolades, including the 1995 ACM Software System Award and induction into the Internet Hall of Fame in 2012.
