They showed that DNA carries genetic material.
Hershey and Chase significantly advanced our understanding of genetics through their famous 1952 experiment using bacteriophages, which are viruses that infect bacteria. They demonstrated that DNA, and not protein, is the genetic material by showing that only the DNA from the phages entered bacterial cells and directed the production of new viruses. This finding provided crucial evidence supporting the role of DNA in heredity, laying the groundwork for molecular genetics and our understanding of how traits are passed from one generation to the next. Their work helped clarify the molecular basis of genetic inheritance and the importance of DNA in living organisms.

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.

The Hershey-Chase experiment was important because it provided definitive evidence that DNA, not protein, is the genetic material responsible for transmitting hereditary traits. This experiment helped establish the central role of DNA in molecular biology and genetics. It also supported the theory that genetic information is encoded in the sequence of nucleotides in DNA molecules.
Alfred Hershey and Margaret Chase confirmed that DNA is a genetic material.
