Frederick Griffith (1879 - 1941) was a English medical officer and geneticist. In 1928, during an experiment, he discovered what he called a transforming principle, but today we call DNA.[1][2]

Early life[change | change source]

He was born in Hale, Lancashire and attended Liverpool University where he studied genetics. In his younger days he worked at the Liverpool Royal Infirmary, the Thompson Yates Laboratory, and the Royal Commission on Tuberculosis.

Griffith's experiment[change | change 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 | change 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 Avery, along with coworkers Colin MacLeod and Maclyn McCarty, in 1944. The Avery–MacLeod–McCarty experiment.[3]
