Book of condolences / Kondolenzbuch

We are deeply saddened by the sudden and untimely loss of Professor Marcus Maurer, an esteemed leader in dermatology and allergy, with over 850 published articles and 55 books and chapters that greatly advanced allergy research and treatment. Prof. Marcus Maurer played a key role in founding the GA2LEN Urticaria and Angioedema Network of Reference and Excellence - UCARE/ACARE. These over 100 centers worldwide are a testament to Prof. Marcus Maurer’s dedication to building strong relationships between patients and physicians who provide exceptional clinical care and lead pioneering research. He was deeply devoted to enhancing patient care, advancing research, and elevating patient voices through educational initiatives. Prof. Marcus Maurer’s contributions to the Center of Allergy and Immunology, Tbilisi, Georgia is so huge. He warmly hosted us at Charité and conducted a comprehensive audit in Tbilisi for UCARE, ACARE, and ADCARE certification. Since 2018, he paved the way for a valuable friendship and collaboration between us and Charité, personally engaging with us and other UCARE and ACARE Centers worldwide. As a result, we have consistently participated in GA2LEN Meetings, Webinars, LevelUp/Journal Clubs, Forums, etc. We collaborated on research projects, published scientific articles, book chapters, and guidelines. Most importantly, through this cooperation, we gained many new friends and colleagues. Today, we are proudly double-certified as a UCARE/ACARE and ADCARE Center (Atopic Dermatitis Network of Reference and Excellence), and we have recently joined the Anaphylaxis and Food Allergy - ANACARE Network after certification. Professor Marcus Maurer was a steadfast supporter of all initiatives. His leadership and exceptional interpersonal skills allowed him to develop various collaborative activities within the UCARE/ACARE Network, where he served as a driving force behind these efforts. His attention, encouragement, scientific passion, and tireless work were exemplary models for us to follow. He continuously inspired us with fresh ideas, new research interests, and an unwavering dedication. Someone who always finds a way is often described as resourceful and highly gifted. Such individuals possess a remarkable ability to solve problems and develop creative solutions, even in situations where others might struggle. Resourceful people excel at thinking outside the box, finding alternative approaches, and making the most of available resources to achieve their goals. Professor Marcus Maurer embodied these qualities. His motto was "Never give up!" and he was a constant source of help, always finding solutions no matter the circumstances. His sudden and mysterious death is truly heartbreaking and difficult to comprehend. Our thoughts are with his family, friends, and everyone who had the privilege of working with him. Words cannot convey the depth of our sorrow or how much we will miss our beloved Marcus.
