Alfred Hershey was an American bacteriologist and geneticist who shared the 1969 Nobel Prize in Physiology or Medicine. He is best known for the 1952 Hershey-Chase experiment, which provided definitive evidence that DNA, rather than protein, serves as the genetic material of viruses. His research ut...

Peter Doherty is an Australian immunologist and veterinary surgeon whose research advanced the understanding of cell-mediated immunity. Working with Rolf Zinkernagel in the 1970s, he discovered that the immune system's T cells must recognize both the virus and a specific self-marker, known as the ma...

Donald Pinkel was an American pediatric oncologist best known for his work developing combination chemotherapy treatments for childhood cancer. As the first director of St. Jude Children's Research Hospital in Memphis, he led the team that created the "Total Therapy" protocols in the 1960s. This mul...

Harold Varmus is an American physician and biomedical researcher who made significant contributions to the understanding of cancer genetics. Working alongside J. Michael Bishop at the University of California, San Francisco, he co-discovered that cancer-causing genes originate from normal cellular g...

Max Delbrück was a German-American biophysicist who shared the 1969 Nobel Prize in Physiology or Medicine for his pioneering work in molecular genetics. His research focused on the replication mechanisms and genetics of bacteriophages, which are viruses that specifically infect bacteria. He was inst...

Julius Axelrod was an American biochemist who shared the 1970 Nobel Prize in Physiology or Medicine for his fundamental discoveries concerning the chemical transmission of nerve impulses. He identified the process of neurotransmitter reuptake, demonstrating that neurotransmitters are actively recycl...

Gary Ruvkun is an American molecular biologist and professor at Harvard Medical School whose research focuses on the genetic mechanisms of development and aging. In the early 1990s, working with the nematode Caenorhabditis elegans, he co-discovered microRNA (miRNA), a class of small non-coding RNA m...

Victor Ambros is an American developmental biologist whose research at the University of Massachusetts Medical School has focused on gene regulation. In 1993, while studying the nematode Caenorhabditis elegans, he discovered the *lin-4* gene, which produces a short RNA molecule rather than a standar...

Satoshi Omura is a Japanese microbiologist and biochemist recognized for his work in isolating novel natural products from soil bacteria. While researching strains of Streptomyces, he discovered the compound avermectin, which his research partner William Campbell subsequently modified into the drug...

William Campbell, Irish-American biologist, shared the 2015 Nobel Prize in Physiology or Medicine for discovering avermectin, a drug that effectively controls roundworm infections in humans and animals.
