At age 37, Baltimore won the Nobel Prize with Renato Dulbecco and Howard M. Temin "for their discoveries concerning the interaction between tumour viruses and the genetic material of the cell", specifically the discovery of the enzyme reverse transcriptase. He contributed to immunology, virology, cancer research, biotechnology, and recombinant DNA research. He also trained many doctoral students and postdoctoral fellows, several of whom have gone on to notable and distinguished research careers. In addition to the Nobel Prize, he received a number of other awards, including the U.S. National Medal of Science in 1999 and the Lasker Award in 2021.
