According to my bio book, I think it's Alfred Hershey and Martha Chase, in the HERSHEY-CHASE experiment.
phosphorus - 32P
Radioactive sulfur and phosphorous. Proteins contain sulfur, but no phosphorous. Nucleic acids contain phosphorous, but no sulfur. The T even phages they used were nucleic acid enclosed in a capsid of protein. So, to label them radioactively told them by experiment which substance, nucleic acid or protein, was the generic material. To only use one radioactive substance would have been useless in telling which was the genetic material. Google Hersey and Chase for more detail.

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 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.

Phosphorous 32 was used to label the Nucleic Acid. Sulfur 35 was used to label the protein. The progeny of the E. coli cells Hershey and Chase grew the virus in had Phosphorous 32 in them which concluded that the DNA went inside and was the genetic material. The phage coating left on the outside tested positive for Sulfur 35 which meant protein was left on the outside.

These two isotopes are: phosphorus-32 and sulfur-35.
