Hershey and Chase's experiment worked because they used radioactive labeling to track the DNA and protein separately. This allowed them to determine that only the DNA, not the protein, was passed on to the next generation of bacteria.
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.

Hershey and Chase
According to my bio book, I think it's Alfred Hershey and Martha Chase, in the HERSHEY-CHASE experiment.
Hershey and Chase discovered that after the P-labeled phages infected the bacteria, most of the radioactive phosphorus was found in the viral DNA, while little to no radioactive sulfur (used to label protein) was found. This confirmed that genetic material, not protein, is responsible for heredity in viruses.
Hershey and Chase used radioactive sulfur-35 to tag phage proteins and radioactive phosphorus-32 to tag phage DNA in their experiments on bacteriophages.
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.

The Hershey-Chase blender experiment helped prove that DNA, not protein, is the genetic material of a bacteriophage. By using radioactive labeling, they were able to track the transmission of genetic material from the virus to the infected bacteria, showing that it was the DNA and not the protein coat that carried the genetic information.
