There he became chief of the division of bacteriology at the Jewish Hospital of Brooklyn, N.Y. In addition to his studies on scarlet fever, its causes and its effects, Friedemann did research on tetanus, virus diseases, latent infections and their significance to epidemiology, and the theory of anaphylactic shock. -BIBLIOGRAPHY: S.R.
