- Joined the Rockefeller Institute.
1917 - His career-long studies of the pneumococcus bacterium included the immunological classification of this organism.
1944 - His subsequent pneumococcal research, summarized, indicated that the agent that transforms non-virulent strains to virulent was DNA, thus demonstrating that DNA is the chemical basis of heredity.
1948 - Avery did his Pneumococcus work at the Rockefeller and stayed there until his retirement.
