Over decades, Jean-Jacques Cassiman was linked inseparably to the destiny of the European Society of Human Genetics, which he accompanied through its rebirth by facilitating the incorporation of ESHG in Belgium in 1991.
"JJ" had the role of ESHG Secretary General (1991-1997), ESHG President (2008-2009), and became first awardee of the EHSG Honorary Award in 2014. He also co-founded the International Federation of Human Genetics Societies in 1996.
Jean-Jacques passed away peacefully and serenely in the presence of his family on Friday, August 5. He will be sorely missed by all who knew and advanced together with him.
