This paper is focused on life and scientific achievement of Edward Korczyński, professor of internal diseases in Jagiellonian University, which is seen by many as a pioneer of modern clinic of internal disease in Poland. Korczyński's name is given just aside such great physicians as Joseph Dietl or Tytus Chałubiński. It is due to his works nitroglycerine was introduced into clinical practise, and it is him, who first in the world could diagnose infarct of the heart in a patient, which became classical and canonical in medicine.
