Legends of Allergy and Immunology: Johannes Ring

Johannes Ring has shaped allergology for more than five decades. His scientific work ranges from early studies on anaphylaxis and drug hypersensitivity to atopic dermatitis, the atopy patch test and the role of environmental factors in allergic disease. But this is only one part of his legacy. As a clinician, the patient was always at the centre of his thinking, and many of his research questions came directly from clinical observation. As a mentor, he encouraged young physicians and scientists to be curious, critical of their own results and, most importantly, to find their own scientific path. Many of his former trainees today hold leading positions in allergology and dermatology across Europe. For me, Johannes Ring has been a mentor for more than two decades-and still is. At 80, he has taken on a new role in Davos. He is clearly not finished yet.
