OSWALD AVERY Avery was born in Halifax, Nova Scotia 1877. Despite a promising career in the church, offered to him through his father, he desired greater intellectual stimulation. His frustration in his inability to help some of his patients motivated him to devote his career to the systematic effort to understand the biological activities of bacteria. This could only be attained by knowing their chemical composition.

a fellow colleague at the institute. McCarty and Avery concentrated on the phenomenon of pneumococcal transformation, in which R-form (non virulent) bacteria changed into the S-form (virulent) when killed S-form bacteria were added to the culture. The changed bacteria were identical in virulence and type to the killed bacteria and the changes were permanent and inheritable.

Avery’s early work came to the attention of the director of the Hospital of the Rockefeller Institute for Medical Research. In 1913 he focused most of his research for the next thirty-five years on a single species of pneumonia-creating bacteria, Diplococcus pneumoniae. There he worked along some of the elite in their fields, including Rene Dubos, Maclyn McCarty, Colin MacLeod and Alphonse R Dochez. However it was in 1944 that Avery made his legacy along with

Soon after this discovery, Avery and McCarty soon isolated this transforming substance from their samples of the pneumococci and discovered the substance to be deoxyribnonucleic acid. Or DNA. The paper proved that the transforming principle or heredity material, was DNA and not protein as most scientists had assumed. Avery played an early and critical role in the molecular revolution in biology.
