In order to celebrate the 40th anniversary of EARN <https://earn-history.net/> , the EARN 2024 conference will take place in Athens on April 20-21 2024, in conjunction with the RIPE SEE 12 <https://www.ripe.net/membership/meetings/regional-meetings/see/see-12/#:~:t ext=The%2012th%20South%20East%20Europe,on%2023%2D24%20April%202024.> Meeting. EARN, the European Academic and Research Network, started in 1984 as the first multi-vendor computer communications network in Europe before the Internet became widely available in the region. For the next ten years, until it merged with RARE (Réseaux Associés pour la Recherche Européenne) to form TERENA in 1994, EARN was active in introducing computer networking throughout Europe and beyond (former Soviet republics, the Middle East and North Africa). Among the speakers at the conference the Internet Hall of Fame inductees: Dennis Jennings <https://www.internethalloffame.org/inductee/dennis-jennings> Frode Greisen <https://www.internethalloffame.org/inductee/frode-greisen/> François Flückiger <https://www.internethalloffame.org/inductee/francois-fluckiger/> Jan Gruntorád <https://www.internethalloffame.org/inductee/jan-gruntorad/> Daniel Karrenberg <https://www.internethalloffame.org/inductee/daniel-karrenberg/> We invite all those interested in the history of computer networks to join us at the conference and share ideas, lessons learned, memories and history.
