The General Committee of ECHA decided to celebrate the 30th birthday of ECHA by collecting the available information and memories of our past 15 International ECHA Conferences. These conferences were always the highlights of ECHA’s life, which gave again and again a great impetus for research, its applications and cooperation both in gifted education and talent support. The Committee asked Ragnild Zonneveld to mobilize the collective memory of ECHA on its conferences. Please find an Introduction and the history of all 15 past International ECHA Conferences here. We wish a great next 30 years to ECHA in cooperation and enrichment!
