Famous American Biologists

Right IconThis ranking is based on an algorithm that combines various factors, including the votes of our users and search trends on the internet.

A biologist work basically involves conducting fundamental research on living organism, exploring and explaining the underlying mechanism that governs the functioning of the organism. The area of study for a biologist is however not limited to working on micro and multi-cellular organisms alone, their field often overlapping between botany, zoology, microbiology, genetics and evolution biology. From developing vaccines to devising the theories regarding the beginning and progression of life, it is the work by biologists that have helped improve our understanding of nature and our living standard. America has had a long list of biologists who have through their extensive work contributed to some of biology’s greatest findings. Edward Henri Fischer, Fritz Albert Lipmann, Gerald Maurice Edelman, Herbert Spencer Gasser, Howard Martin Temim, Alfred Hershey, Edward B Lewis are some such world-renowned American biologists. Broadly classified under the division of biology, these American biologists have significantly contributed to the scientific world. For the same, many of them have been awarded with Nobel Prize as well. Check this segment and find out more about the life of American biologists and their revolutionary works.
