Palade was a cell biologist who helped determine cell function and organisation. He and colleagues demonstrated that all plant cells and some animal and bacteria cells have a vacuole, an enclosed compartment in the cell membrane, which contains enzymes essential to maintaining the cell's health. In 1974 he was awarded the Nobel Prize in Physiology and Medicine for his innovations in electron microscopy and cell fractionation, which laid the foundation for molecular cell biology, and his discovery of the ribosomes of endoplastic reticulum in 1955.

de Duve was a cytologist and biochemist. The son of Belgian refugees who fled to England during World War I, de Duve is associated with the discovery of peroxisome and lysosome in the 1950s and 1960s. They are two specialised subunits found within the cell and are vital to the function of the cell. His work paved the way to unravelling the biology of several genetic diseases. He was awarded the Nobel Prize for Medicine in 1974 on the back of his 'discoveries concerning the structural and functional organisation of the cell.'
de Duve helped determine the structure and function of parts of the cell. 1917-10-02T00:00:00+0000| 2 Oct 1917 | | Christian R de Duve was born in Thames Ditton, United Kingdomde Duve | Rockefeller University | Cell |
A geneticist by training, Sager enjoyed two careers. She first made her mark in the 1950s and 1950s when she discovered the transmission of genetic traits through chloroplast DNA. This was the first example of genetics not involving the cell nucleus. Later on, in the early 1970s, she became a major pioneer in cancer genetics. She was one of the first to propose and investigate the function of tumour suppressor genes. 1918-02-07T00:00:00+0000| 7 Feb 1918 | | Ruth Sager was born in Brookline, Massachusetts, USASager | Rockefeller University | Genetics, Oncology |
Daly trained as a biochemist and was the first Black American woman to earn a doctorate in chemistry (from Columbia University, 1947). Her early research looked at the effects of cholesterol on the mechanisms of the heart, the effects sugars and other nutrients on the health of the arteries and the impact of advanced aged and hypertension on the circulatory system. This she did at Rockefeller Institute in New York. She subsequently joined Columbia University where she investigated how proteins are produced and organised in the cell. In addition to her scientific work, Daly was an ardent campaigner for getting minority students into medical school and graduate science programmes. 1921-04-16T00:00:00+0000| 16 Apr 1921 | | Marie M Daly was born in Corona, Queens, NY, USAMary Daly | Rockefeller Institute, Columbia University | Biochemistry, Cardiovascular |
Merrifield was a biochemist and organic chemist. In 1984 he was awarded the Nobel Prize for Chemistry for inventing a process known as solid phase peptide synthesis. He developed the technique in 1965. It provided a methodology for chemical synthesis on a solid matrix. By the mid-1960s he and his team had proved the method could be used to synthesise bradykinin, angiotensin, desamino-oxytocin and insulin. In 1969 they managed to synthesise the enzyme, ribonuclease A. This was the first proof of the chemical nature of enzymes. Merrifield's method is now a rountine method for automatically synthesising large proteins, novel nucleotides, or short fragments of DNA.1921-07-15T00:00:00+0000| 15 Jul 1921 | | Robert Bruce Merrifield born in Fort Worth, Texas, USAMerrifield | Rockefeller Institute | Biochemistry |
Known as the Carrel or T flask, this vessel was developed by Alexis Carrel. The flask had an angled neck to prevent airborne particles from falling into the flask when it was open. The neck could also be sterilised with a flame both before and after adding or removing nutrient broth. 1923-01-01T00:00:00+0000| 1923 | | First specifically designed cell culture vessel Carrel | Rockefeller University | Cell culture |
Loeb was a German-American physiologist and biologist who demonstrated the possibility of reproduction without male fertilisation, parthenogenesis, in sea urchin eggs. He found it was possible to stimulate embryonic development in the eggs of sea urchins without sperm by making slight chemical changes to the water where the eggs were kept. This he discovered while conducting experiments at the Marine Biological Laboratory in Woods Hole, Massachusetts. His results were published in 'Activation of the unfertilized egg by ultra-violet rays', Science, 40/1036 (1914), 680-1. While Loeb was nominated for the Nobel Prize many times he never won.

Greengard is a neurobiologist who shared the 2000 Nobel Prize for Medicine for his discovery of how the neurotransmitter, dopamine, functions in the nervous system. Beginning this work in the late 1960s, Greengaard showed that dopamine binds to receptors on the outer membrane of a neuron. This stimulates a second messenger, cyclic AMP, which in itself activates an enzyme that adds phosphate molecules to other proteins in the neuron. Greengard's work has paved the way to greater understanding of certain neurological and psychiatric disorders and development of new treatments. 1925-12-11T00:00:00+0000| 11 Dec 1925 | | Paul Greengard was born in New York, USAGreengard | Rockefeller University | Neuroscience |
The vaccine was developed by Alexis Carel with Tom Rivers. It was made from vaccinia, or cowpox virus, collected from calf lymph fluid. The vaccine did not prove successful as it did not provide sufficient protection against smallpox, but it showed a way of developing safer vaccines by growing the virus in tissue culture. The technique was published in A Carrel, TM Rivers, 'La Fabrication du vaccin in vitro', Comptes Rendus Soc Biol, 96 (1927), 848. One of the advantages with the new method was that the vaccine had fewer side effects and did not leave a scar after vaccination. 1927-01-01T00:00:00+0000| 1927 | | First viral vaccine developedCarrel, Rivers | Rockefeller University | Cell culture, Vaccines |
Noguchi was a Japanese bacteriologist. He is best remembered for his identification, in 1913, of the causative agent of syphilis (the bacteria Treponema pallidum), and identification of the pathogen responsible for Carrion's disease (a Leishmania parasite). Unable to get a medical position in Japan because of his hand deformity which potential employers feared would put off potential patients, Noguchi spent his life doing laboratory work in the United States. While valued in his lifetime, his reputation took a battering after his death because researchers struggled to reproduce some of his claims, including having discovered the cause of yellow fever, polio and rabies. 1928-05-21T00:00:00+0000| 21 May 1928 | | Hideyo Noguchi diedNoguchi | Rockefeller Institute | Bacteriology, Infectious diseases |
Zinder was a biologist who discovered how hereditary information is transferred from one organism to another. The process is known as genetic transduction. Carrying out experiments with the bacteria species Salmonella, Zinder discovered that bacteriophages, a type of virus, carry genes from one bacterium to another. He did the work with Joshua Lederberg, his doctoral supervisor. 1928-11-07T00:00:00+0000| 7 Nov 1928 | | Norton D Zinder was born New York City, USAZinder | Rockefeller University | Genetics |
Edelman was a biologist renowned for his research on antibodies. His research helped determine the chemical structure of antibodies in the early 1960s. It showed that antibodies were made up of two light and heavy chains linked together by disulfide bonds. The breakthrough immediately galvanised feverish activity in all fields of immunological science, paving the way to the development of antibodies for both diagnostics and therapy. Edelman was awarded the Nobel Prize for Medicine in 1972 for his work.1929-07-01T00:00:00+0000| 1 Jul 1929 | | Gerald M Edelman was born in New York NY, USAEdelman | Rockefeller University | Antibodies, Immunology |

Wollstein was a pioneering American paediatric pathologist at a time when women rarely worked in the field of pathology. One of her key contributions was the development of antiserum therapies to treat both paediatric and adult infectious diseases, including a potent polyvalent antiserum to treat meningitis. She was the first woman to ever be elected a member of the American Pediatric Society. In 1904 she joined the Rockefeller Institute for Medical Research where she did important experimental work on polio, pneumonia and other diseases. Her work was important for showing that mumps could be viral in nature.1939-09-30T00:00:00+0000| 30 Sep 1939 | | Martha Wollstein diedWollstein | Rockefeller Institute for Medical Research | Antibodies, Infectious diseases |
A Russian-American biochemist, Levene discovered nucleic acids came in two forms: DNA and RNA. He also identified the components of DNA: adenine, guanine, thymine, cytosine, deoxyribose and a phosphate group and showed that these components were linked together by nucleotides, phosphate-sugar base units. Born to Lithuanian Jewish parents, Levene emigrated to the US in 1893 as a result of anti-semitic progroms. He was appointed the head of the biochemical laboratory at the Rockefeller Institute of Medical Research in 1905 where he spent the rest of his career. 1940-09-06T00:00:00+0000| 6 Sep 1940 | | Phoebus Levene diedLevene | Rockefeller University | DNA |
