[Clemens Freiherr von Pirquet, developer of the concept of allergy]. / Revolutionär am Krankenbett.

The pediatrician and scientist, Clemens Freiherr von Pirquet (1874-1929) was the first to coin the term "allergy". His experiments with Behring's serum, which he administered to sick children, led him to an awareness of an interaction between the human organism and pathogens. In his article published in the Müncher Medizinischen Wochenschrift in 1906, he laid the foundation stone for modern allergology.
