that DNA rather than the protein coat of a virus contains the hereditary material.
DNA is a double helix.
Alfred Hershey and Margaret Chase confirmed that DNA is a genetic 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.

In 1928, Frederick Griffith was able to transform harmless bacteria into virulent pathogens with an extract that Oswald Avery proved, in 1944, to be DNA. In 1952, Martha Chase and Alfred Hershey used radioactively labeled virus DNA to infect bacteria, proving the same point.
The scientists Alfred Hershey and Martha Chase conducted a series of experiments at the Carnegie Institute of Washington in 1952, and concluded that the genetic material of a bacteriophage was DNA.
