Håkon Wium Lie, Director

Håkon is a web pioneer, having created CSS while working with Tim Berners-Lee at CERN in 1994. Håkon became a devotee of Prince when looking for a CSS-based tool which could format his book on CSS, co-authored with Bert Bos. Håkon has been the director of Yeslogic, the company that makes the Prince formatter, since 2004. In 2015 he took a break to see if the web is truly worldwide: as the CTO of the Kon-Tiki2 Expedition he communicted over a thin satellite connection from a balsawood raft, sailing from Lima to Easter Island in 43 days.
