American Biologists

American biologists have contributed some of biology's greatest findings. With the increasing importance of genetics, conservation and microbiology, American biologists may yet discover some of nature's most amazing secrets.

George Wald

Wald, George (1906-1997) was an American biochemist who discovered how chemical changes in the retina enable a person to see.


Ames, Adelbert, Jr. (1880-1955) was a visual physiologist who studied optics and perception.

Claude, Albert (1899-1983), a Belgian American cell biologist, helped establish modern cell biology and developed methods to analyze cell structures.

Kinsey, Alfred Charles (1894-1956), a United States zoologist. Sexual Behavior in the Human Male (1948) and Sexual Behavior in the Human Female (1953) were the result of many years of research by Kinsey and his associates.

Hershey, Alfred Day (1908-1997) was an American biologist. He shared the 1969 Nobel Prize in physiology or medicine with the German-born American biologist Max Delbrück and the Italian-born American biologist Salvador Edward Luria for their work on bacteriophages, viruses that attack bacteria.

Sturtevant, Alfred H. (1891-1970) was an American geneticist and the first to discover the procedure for gene mapping.

Schally, Andrew Victor (1926-) is a Polish-born American biochemist. He won the 1977 Nobel Prize in physiology or medicine for his research concerning the role of certain hormones (useful chemical substances) in the chemistry of the body.

Kornberg, Arthur (1918-), an American physician and biochemist, was the first to discover how molecules of deoxyribonucleic acid (DNA) duplicate within bacterial cells and also the first to devise a method for synthesizing this process in a laboratory setting.

Gray, Asa (1810-1888), a United States botanist. Gray made important improvements in the system used to classify plants.

McClintock, Barbara (1902-1992), a United States geneticist. She won the Nobel Prize in physiology or medicine in 1983 for her discovery that certain genes in corn can move from one position to another along the length of a chromosome, causing genetic mutations.

Commoner, Barry (1917-) is an American biologist and educator who has become known as a leading environmental activist.
