Knorr patented the compound in 1883. Filehne later suggested the names Höchstin or Knorrin for the substance but Knorr telegraphed from his honeymoon that his variant of the name, antipyrine, is not to be changed. (German: Antipyrin bleibt!).[4] In 1885 Knorr married Elisabeth Piloty, the sister of his laboratory colleague Oskar Piloty at the University of Munich.[2]
