Oswald T. Avery joined the Rockefeller Hospital in 1913 to work on developing a therapeutic serum for pneumonia. In the 1920s and 1930s his laboratory performed innovative research on the relationships between the chemical components of pneumococcus and the immune reactions the bacterium elicits. However Avery is best known for his discovery that deoxyribonucleic acid (DNA) serves as genetic material. In 1944 Oswald Avery, Colin MacLeod, and Maclyn McCarty demonstrated DNA for the pneumococcus is the genetic material in all cells.
