Oswald Theodore Avery Jr. (October 21, 1877 – February 20, 1955) was a Canadian-American physician and medical researcher. The major part of his career was spent at the Rockefeller Hospital in New York City.
Oswald Avery was a Canadian-born American bacteriologist whose research helped ascertain that DNA is the substance responsible for heredity, thus laying the foundation for the new science of molecular genetics. His work also contributed to the understanding of the chemistry of immunological.

Oswald Avery led the team that discovered DNA passes heredity instructions through successive generations of organisms – it carries the chemical code of life. Avery and his colleagues published their discovery in a classic paper describing what came to be known as the Avery–MacLeod–McCarty experiment.
Jan 20, 2014 · Seventy years ago, Oswald Avery and his colleagues from the Rockefeller Institute published the first evidence that genes are made of DNA. Their discovery was received with a mixture of enthusiasm, suspicion and perplexity.

Although many scientists acknowledge the impact of Avery's work on the field of molecular biology, Oswald Avery did not win a Nobel Prize. The reason might be that Avery never publicly stated that a gene is made of DNA. In his paper, Avery showed that DNA is the transforming principle.

Apr 23, 2013 · Oswald Avery, Colin MacLeod, and Maclyn McCarty showed that DNA (not proteins) can transform the properties of cells, clarifying the chemical nature of genes. Avery, MacLeod and McCarty identified DNA as the "transforming principle" while studying Streptococcus pneumoniae, bacteria that can cause pneumonia. The bacteriologists were interested ...
