He showed that the DNA from strain S cells could transform strain R cells.
The question was ,"What substance was responsible for transformation?" psst. it was DNA, (:
Frederick Soddy won the Nobel Prize in Chemistry in 1921.

I have no answer to that.

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

Frederick Griffith, a British bacteriologist, focused on the epidemiology and pathology of bacterial pneumonia. He showed that Streptococcus pneumonia, implicated in many cases of lobar pneumonia,[2] could transform from one strain into a different strain. This was later identified as DNA.
Frederick Griffith discovered Transformation doing lab experiments in the 1930's. He initially based his work of Gregor Mendel, the father of genetics, and discovered more as he experimented of lab mice.

Frederick Griffith introduced the Griffith experiment in 1928. This experiment proved that bacteria can carry genetic information through a process called transformation.
