Tim Berners-Lee, a British scientist working at the European Organization for Nuclear Research (CERN), along with with his associate Robert Cailliau, were operating the first web server, info.cern.ch, and first web browser/editor, WorldWideWeb, which were reportedly able to communicate over the Internet by this date. Running on a pair of NeXT workstations, the exact date that everything was truly functioning for the first time is lost to history, but according to Berners-Lee, it was functional by the time the Christmas holiday care around that year.
Interestingly enough, Berners-Lee and his wife were also expecting their first child, due on Christmas Eve. The baby was not born until New Year’s Day, however. Regardless, in essence Tim Berners-Lee fathered two babies during the 1990 holiday season!
