Study Notes

Important Biologists

Anton van Leeuwenhoek (1632-1723): Born in Delft, Netherlands. His interest in lenses led him to be the first to observe single-celled organisms. He is considered a biologist and the father of microbiology.

Robert Hooke (1635-1703)

Born in the Isle of Wight, England. Received higher education at Oxford University. Studied physics and chemistry. His work includes the application of microscopy and the discovery of "cells" in 1665 using cork.

Robert Brown (1773-1858)

Scottish botanist. Introduced the model that describes random movements of cells, known as Brownian motion. His contribution was the description of the cell nucleus in all living things.

Charles Darwin (1809-1882)

Attended the University of Cambridge and studied medicine at the University of Edinburgh. He was considered a naturalist. He proposed the concept that all species of life came from a single source (Theory of Evolution). His theory marked the beginning of the discussion about natural selection.

Gregor Mendel (1822-1884)

Austrian scientist/monk. His work, "Experiments on Plant Hybridization" paved the way for biology students to study genetic traits in peas. He found that a specific trait would be dominant over other traits in the same species (Mendelian Inheritance).

Louis Pasteur (1822-1895)

French chemist and biologist. He proved the germ theory of disease and invented the process of pasteurization. He is best known for his work on the development of vaccines for rabies, anthrax, cholera, TB and smallpox.

James D. Watson (b. 1928), and Francis Crick (1916-2004)

Jointly received the Nobel Prize in Physiology/Medicine in 1953 for their determination of the structure of DNA (deoxyribonucleic acid), a double helix model. This model provided a physical basis for Mendel's genes. Their work had a major impact on biological genetics. Their impact enabled researchers to understand the genetic code.
