Work

He was one of the first German medical professors to lecture in the vernacular tongue instead of Latin. Schönlein described purpura rheumatica (Schönlein's disease) an allergic non-thrombopenic purpura rash that became known as Henoch–Schönlein purpura, though now known as IgA vasculitis.^[3][4] He also discovered the parasitic cause of ringworm or favus (Trichophyton schönleinii).^[5]

J. L. Schönlein first published the name "tuberculosis" (German: Tuberkulose) in 1832.^[6][7] Prior to Schönlein's designation, tuberculosis had been called "consumption".
