Friedrich Wegener (7 April 1907, Varel – 9 July 1990, Lübeck, [veːɡɐnəɐ̯]) was a German pathologist who is notable for his description of a rare disease originally referred to Wegener disease and now referred to as granulomatosis with polyangiitis. Although this disease was known before Wegener's description, from the 1950s onwards it was generally referred to as Wegener's granulomatosis.[1]
