Oswald Avery (jan 1, 1944 – dec 31, 1944)
Description:
Avery discovered that DNA, not proteins, carries genetic information. His experiments with bacteria showed that DNA could transform harmless bacteria into harmful ones. This built on Frederick Griffith’s work on transformation and set the stage for understanding DNA as the molecule of heredity. (https://dnalc.cshl.edu/view/15674-Oswald-Avery-c-1930-.html)
