Who made a living bacteria out of dead?

Frederick Griffith in 1928 using two different types of the bacterium Streptococcus pneumoniae first demonstrated bacterial transformation.


Who was the scientist who demonstrated genetic tranformation by injected mice with two different strains of Streptococcus pneumoniae bacteria?

The scientist was Frederick Griffith, in 1928. Although he believed proteins were involved, it was actually the transfer of DNA. The harmless pneumonia bacteria acquired the DNA from the killed viruses, and became equally lethal.
