Famous 20th Century Molecular Biologists

James Watson is a geneticist, molecular biologist, and zoologist. He is credited with co-authoring the academic paper that propounded the double helix structure of nucleic acids such as DNA for which he was awarded the Nobel Prize in 1962. In 1977, he was honored with the Presidential Medal of Freedom. In 1997, he was awarded the National Medal of Science.

Nobel Prize-winning British biophysicist Francis Crick is best known for his ground-breaking work to determine the structure of the DNA, along with James Watson, Maurice Wilkins, and Rosalind Franklin. He taught at various institutes, such as the Salk Institute, and was also awarded the Order of Merit.

Matthieu Ricard is a French photographer, writer, translator, and Buddhist monk. He serves as a board member of the popular not-for-profit organization Mind and Life Institute. After having received a Ph.D. degree from the Pasteur Institute, Ricard gave up his scientific career to practice Tibetan Buddhism. He is also the co-founder of another international non-profit organization, Karuna-Shechen.

Sydney Brenner was a South African biologist who made important contributions to various areas of molecular biology, including the genetic code. Brenner shared the 2002 Nobel Prize in Physiology or Medicine with Sir John E. Sulston and H. Robert Horvitz. Sydney Brenner is credited with founding the Molecular Sciences Institute, which is situated in the United States of America.

American molecular scientist Suzanne Eaton had spent most of professional life at the Max Planck Institute. The WICB Junior Award winner had initially also considered alternative academic careers in comparative literature and math. She was raped and murdered by a Greek man in Crete, where she had gone for a conference.

Nobel Prize-winning biochemist and doctor Arthur Kornberg is best remembered for his research on DNA synthesis. Born to Jewish immigrants in New York, Kornberg assisted his father at his hardware shop as a child. He had also been a ship doctor for the U.S. Coast Guard.

Carol W. Greider is a molecular biologist who discovered the enzyme telomerase in 1984. Her discovery was honored several years later when she received the 2009 Nobel Prize for Physiology or Medicine, along with Blackburn and Jack W. Szostak for their work on telomeres.  The trio also shared the Albert Lasker Award for Basic Medical Research for the same work.  

Susumu Tonegawa is a Japanese scientist known for his discovery of the genetic mechanism that produces antibody diversity. For this work, he received the Nobel Prize for Physiology or Medicine in 1987. Even though he won the coveted award for his work in immunology, he is a molecular biologist by training. He now studies neuroscience. 

American molecular biologist and Nobel laureate Walter Gilbert pioneered research on the sequence of nucleotide links in DNA and RNA molecules. The Harvard and Cambridge alumnus later taught at Harvard. He also co-established firms dealing with genetic engineering and pharmaceutical research and was part of the Human Genome Project.

Molecular biologist Max Perutz won a Nobel Prize for his research on the structure of hemoglobin. While working at Cambridge, he co-founded the Medical Research Council Unit for Molecular Biology. He also studied glaciers and their velocity distribution. He was also made a Fellow of the Royal Society.

Nobel Prize-winning doctor Peter Agre revolutionized science with his work on the movement of water molecules inside the cell membrane. Born to a chemistry professor, he developed an interest in science early in his life. He was also associated with the medical schools at Johns Hopkins and Duke University.

Shirley Marie Tilghman, the nineteenth President of Princeton University, currently the Emeritus Professor of Molecular Biology and Public Affairs, is considered to be one of the most influential female scientists of our time. Although she is no longer involved in active research she is known for her contributions in the fields of molecular genetics, especially in genomic imprinting.

Philip Allen Sharp is an American molecular biologist and geneticist best known for co-discovering RNA splicing. In 1993, he received the prestigious Nobel Prize in Physiology or Medicine along with Sir Richard John Roberts. Philip Allen Sharp has also won several other awards, such as the National Medal of Science, the Benjamin Franklin Medal, and the Louisa Gross Horwitz Prize. 

Molecular biologist Richard J. Roberts is best known for his Nobel Prize-winning research on split genes. The Harvard alumnus had wished to be a detective as a child but changed his mind after being gifted a chemistry set. He was also made a Fellow of the Royal Society and knighted.

Known for his independent work on ribonucleic acid (RNA), molecular biologist Sidney Altman co-won the 1989 Nobel Prize in Chemistry for discovering that RNA, which was thought to be a passive carrier of genetic codes, is also capable of taking up active enzymatic functions. The discovery is significant in that it forced scientists to reexamine traditional theories on cellular functions.  

Born to Polish Jew parents in the Bronx, Seymour Benzer would often cut open frogs in childhood. The molecular biologist is best known for his research on viral genes and for coining the term cistron. A Caltech professor, he was also made a Fellow of the Royal Society.

Cell biologist and MIT professor Susan Lindquist is best remembered for her research on protein folding and its impact on diseases. The Harvard alumna had also taught at the University of Chicago for 23 years. She was also the first female director of the Whitehead Institute for Biomedical Research.

Maclyn McCarty was an American geneticist who became the first person to illustrate that genes were made of DNA. McCarty served as the Rockefeller University Hospital's physician-in-chief for 14 years. He also served as the vice president and a trusted adviser of Rockefeller University.

Kenneth Murray, one of the most influential molecular biologists of his time, was a co-founder of Biogen, which developed hepatitis B vaccines. He often collaborated with his wife, molecular geneticist Noreen, and earned six honorary degrees and a knighthood. He was also a fellow of the Royal Societies of London and Edinburgh.
