Auenbrugger von Auenbrug, LEOPOLD

Auenbrugger von Auenbrug, LEOPOLD, an Austrian physician, born at Gratz in 1722, practised at the Spanish hospital in Vienna, where he died in 1809. As early as 1754 he had discovered the method of investigating internal diseases which afterwards made him famous; but not until after seven years of experiments and verification did he publish his treatise, entitled Inventum novum ex percussione thoracis humani interni pectoris morbos detegendi (Vienna, 1761). See PERCUSSION.
