Biophysicists Delbruck, Luria and Exner. From left: German-US biophysicist Max Delbruck (1906-1981), Italian-US microbiologist Salvador Edward Luria (1912-1991), and US physicist Frank M. Exner. Delbruck and Luria part-shared the 1969 Nobel Prize in Physiology or Medicine for their discoveries in bacterial and viral genetics. Exner worked with Luria on the inactivation of bacteriophages by X-rays. Photographed in 1941, during the Ninth Symposium on Quantitative Biology (Genes and Chromosome Structure, 18 June to 2 July) at the Carnegie Institution Department of Genetics (later Cold Spring Harbor Laboratory), New York, USA.
