[The cognitive process of Robert Koch in becoming the founder of tuberculosis control].

The development of Robert Koch to a scientist with enormous effects to the picture of modern medicine and society is interpreted from the point of view of today. Koch has critically acquired the great scientific progress of his time by reason of his excellent gifts; he has confirmed them and has extended them fundamentally by his discoveries. Koch possessed the prerequisites for it due to his systematic, persevering and comprehensive way of working and his assiduity making him one of the originators of bacteriology, the creator of the control of infectious diseases and above all of tuberculosis. His commitment to helping men and community wherever necessary with all his possibilities, has made him a benefactor to humanity.
