+# In Memoriam
+
+This article is dedicated to Sébastien Fourey, co-developer of the G'MIC project, who passed away in October 2024.
+He was the kindest, most caring person you’ll ever meet, as well as being extremely competent and passionate
+about computing, algorithms and software development as a whole. He has always believed in the magic of free software.
+The world has lost a talented developer, a great researcher and teacher, but above all a person of great humanity.
+Rest in peace, Sébastien.
