DNA controls heredity, not proteins.
Bacteriophage
According to my bio book, I think it's Alfred Hershey and Martha Chase, in the HERSHEY-CHASE experiment.
Hershey and Chase
It is not Hershey and Chase !! It is Oswald Avery that conducted these experiments!
Hershey and Chase chose to use viruses in their experiments because viruses are simple and can easily infect and replicate within host cells, making them ideal for studying the process of genetic material transfer.

Alfred Hershey and Martha Chase conducted the famous Hershey-Chase experiment in 1952, which confirmed that DNA, not protein, is the genetic material in bacteriophages. They used radioactive labeling to trace the genetic material within the bacteriophages, providing evidence for the role of DNA in heredity.
The genetic mateial is made of DNA and not of proteins

In their experiments, Hershey and Chase injected chemical tracers that resembled proteins and DNA into a type of rapidly reproducing virus called T2. They then tracked the course of the tracers as they made their way through reproduction and found that the tracers that resembled DNA were much more likely than the tracers that resembled proteins to be found in future generations of the cells. Hershey and Chase concluded that DNA, and not protein, was associated with genetic material.
