Biologists, or those who study biology, have contributed many of the greatest findings in science. A biologist might study anything from cells to human evolution, but their focus always relates back to the study of life.

Eric Richard Kandel

Kandel, Eric Richard (1929-) won the 2000 Nobel Prize in physiology or medicine—along with scientists Arvid Carlsson of Sweden and Paul Greengard of the United States—for his research on the function of brain cells in learning and memory.

Ernest Everett Just

Just, Ernest Everett (1883-1941) was an internationally known American biologist, zoologist, and physiologist who made major contributions to the field of biology through his pioneering research into fertilization, experimental parthenogenesis, and cell physiology.
