Early life[change | edit source]
He was born in Hale, England and attended Liverpool University where he studied genetics. In his younger days he worked for the Liverpool Royal Infirmary, the Thompson Yates Laboratory, and the Royal Commission on Tuberculosis.
Griffith's experiment[change | edit source]
The experiment began when Griffith was trying to make a vaccine to prevent pneumonia infections in the "Spanish flu" influenza pandemic after World War I, by using two strains of the Streptococcus pneumoniae bacterium.
Later life[change | edit source]
Griffith was killed at work in his laboratory in 1941, along with longtime friend and bacteriologist William M. Scott in London during an air raid in the London Blitz. Years later Griffith's "transforming principle" was identified as DNA by Oswald Theodore Avery, along with coworkers Colin MacLeod and Maclyn McCarty, in 1944. The Avery–MacLeod–McCarty experiment.
