Alexander Hollaender

Alexander Hollaender was a leading researcher in radiation biology and in genetic mutations. In 1983 he was given the Enrico Fermi Award by the United States Department of Energy for his contributions in founding the science of radiation biology, and for his leadership in promoting "scientific exchanges" between American scientists and scientists from developing countries.
Hollaender was born in Samter, German Empire, he emigrated to the US in 1921.
In 1939 Hollaender published research showing that the mutations of spores of the ringworm fungus occurred in the same spectrum as the absorption spectrum of nucleic acids indicating that nucleic acids form the building blocks of genes. A young Esther M. Zimmer, who worked with Dr. Hollaender at the U. S. Public Health Service, published with Dr. Hollaender, Eva Sansome and Milislav Demerec in this very early field of x-ray- and UV-induced mutations. In later years, Esther Zimmer became one of the most influential founders of bacterial and bacteriophage genetics. From 1946 to 1966 Hollaender was the director of the Biology Division at Oak Ridge National Laboratories, where he worked with M.
