He obtained his M.D. degree from the University of Berlin in 1874. He worked with Robert Koch from 1879 to 1884[1] as an assistant in the Imperial Health Office in Berlin. In 1884, he became staff physician at the Friedrich Wilhelm Institute in Berlin, and four years later became professor at the University of Greifswald.[2]
His development of original methods of staining rendered an important and lasting service to bacteriology.[2] Early in his career, he began a study of parasitic diseases.[3] Among his discoveries was the organism causing diphtheria (Corynebacterium diphtheriae) and the cause of foot-and-mouth disease (Aphthovirus). His description of the diphtheria bacillus, published in 1884, was the originating cause of an antitoxin treatment.[3] He also created Löffler's serum, a coagulated blood serum used for the detection of the bacteria. In 1887, he founded the Centralblatt für Bakteriologie und Parasitenkunde.[2][4]
The Friedrich Loeffler Institute on the Isle of Riems near Greifswald, as well as the Friedrich Loeffler Institute of Medical Microbiology at the Greifswald Medical School of the University of Greifswald, have been named in his honor.
