that DNA rather than the protein coat of a virus contains the hereditary material.
According to my bio book, I think it's Alfred Hershey and Martha Chase, in the HERSHEY-CHASE experiment.
Hershey and Chase observed that DNA is the identity of the hereditary material in phage T2. Hershey and Chase used radioactive labels to mark the protein of the bacteriaphage in one experiment and the DNA in another.

Alfred Hershey and Margaret Chase confirmed that DNA is a genetic material.
Hershey and Chase's experiment using bacteriophages proved that DNA, not protein, is the genetic material in cells. This discovery was a key milestone in understanding how genetic information is passed from one generation to the next. It laid the foundation for the field of molecular biology.

Hershey and Chase completed research proving that DNA is the "stuff of heredity" and not just protein in 1952. There is information on how they used a bacteriophage to prove this residing on the Answers site.
