It is with deep sadness that I have been informed of Prof. Martha Eibl's departure. She was a great physician-scientist and an inspiration to all of us dedicated to the study of human immunological disorders. More than this, she has been an advocate for the patients and their families and throughout her entire life she has fought to improve diagnosis and treatment, with a special focus on immunoglobulin replacement therapy. At a personal level, I have had the honor to collaborate with her in moving the European Group of Immune Deficiencies become an international society. Beyond medicine and science. Prof. Eibl was a pleasure to talk to - she loved arts, literature and music in particular. She will be deeply missed but her legacy stays with all of us and the patients she loved so much.
