[Bürger's efforts for a productive relationship between physiology research and internal medicine]

On the occasion of the 100th anniversary of Max Bürger's birthday his performances in the field of physiology are summarizingly valued and deduced from Bürger's philosophical conception. For his whole life Bürger felt obliged to the developmental biological ideas of the first half of the last century. So the observation and description of the age-depending change of physiological accomplishments and functions became his essential subject of research. Particular attention deserve his investigations of the intrathoracic pressure as well as his studies on the sex-dependence of courses of the disease. As clinician Max Bürger particularly identified himself successfully with the development of the pathological physiology as subject of instruction and education.
