A physician and bacteriologist, Zinsser isolated the bacterium that causes typhus and developed a protective vaccine against it. In 1935 he published the book 'Rats, Live and History' in which he recounted the effects of typhus on mankind and the efforts to eradicate it. In the book he argued that disease was responsible for more deaths than war. 1878-11-17T00:00:00+0000| 17 Nov 1878 | | Hans Zinsser was born in New York City, USAZinsser | Columbia University, Stanford University, Harvard University |
Beadle, a geneticist, was jointly awarded the Nobel Prize for Medicine in 1958 for discovering the role of genes in regulating biochemical events within cells. He made the discovery in collaboration with Edward Tatum while conducting experiments that exposed Neurospora crassa, a the bread mould, to x-rays to cause mutations. They found that the mutations caused changes in specific enzymes that were involved in metabolic pathways. The work was done at Stanford University.1903-10-22T00:00:00+0000| 22 Oct 1903 | | George Wells Beadle was born in Wahoo, Nebraska, USABeadle | California Institute of Technology, Stanford University |
Tatum was a biochemist who shared the 1958 Nobel Prize for Medicine for discovering how genes regulate biochemical events in cells. This was based on some experiments he carried out with colleagues at Stanford University in 1941 which involved crossing normal strains of the pink bread mould, Neurospora crassa, with another strain of the mould they had exposed to X-rays to induce genetic mutations. The offspring were found to inherit the mutation which manifested itself as metabolic defect. This led them to conclude that there was a direct link between genes and enzymatic reactions.

Kornberg was a biochemist renowned for his research on enzymes which create DNA. In 1956 he and his team isolated the first enzyme known to be involved in the replication of DNA. It would be called DNA polymerase I. For this work Kornberg shared the 1959 Nobel Prize for Medicine. The Prize was given for the discovery of the 'mechanisms in the biological synthesis of ribonucleic acid and deoxyribonucleic acid.'1918-03-03T00:00:00+0000| 3 Mar 1918 | | Arthur Kornberg was born in Brooklyn NY, USAKornberg | Stanford University |
Djerassi trained as a chemist and became known for his work in the chemistry of steroids, structure of alkaloids, antibiotics and terpenoids. He helped synthesised drugs like antihistamines, oral contraceptives and anti-inflammatory compounds. In 1951 Djerassi synthesised the progestin noethisterone together with Luis Miramontes. The compound was first introduced for the treatment of gynaecological disorders and then combined with an oestrogen for use as an oral contraceptive pill in 1963. Refused Austrian citizenship after Anschluss because of his Jewish background, Djerassi escaped the Naxi regime by fleeing to Bulgaria with his mother where they stayed for a year before moving to the USA.1923-10-29T00:00:00+0000| 29 Oct 1923 | | Carl Djerassi was born in Vienna, AustriaDjerassi | Syntex, Stanford University |
Berg is an American biochemist. He first made his name in 1971 by demonstrating it was possible to insert DNA from a bacterium into the a virus' DNA, creating what is called recombinant DNA. This he did as part of his work to study viral chromosomes. He was awarded the Nobel Prize in 1980 for this work. His technique paved the way to the development of genetic engineering and the modern biotechnology industry. Berg was also instrumental in the setting up of the Asimolar Conference on Recombinant DNA, in 1975, which drew up the first guidelines for experiments with genetic engineering. 1926-06-30T00:00:00+0000| 30 Jun 1926 | | Paul Berg was born in New York NY, USABerg | Stanford University |
Falkow was a microbiologist who made his scientific mark by showing how bacteria develop resistance to antibiotics. During the 1960s he demonstrated that bacteria could acquire resistance by swapping genetic material via plasmids, small microbial DNA molecules. Thereafter he focused his attention on how pathogens cause disease and in 1985 helped to identify a single genetic locus in Yersinia pseudotuberculosis, a Gram-negative bacteria, that accounts for its ability to infect cultured animal cells. He later showed that a sub-type of E. coli caused a life-threatening diarrhoea prevalent in many low-income countries. Known as the founder of molecular pathogenesis, Falkow's work paved the way to the development of new vaccines, including for whooping cough. He also helped to devise a uniform nomenclature for bacterial plasmids1934-01-24T00:00:00+0000| 24 Jan 1934 | | Stanley Falkow was born in Albany, New York, USAFalkow | Georgetown University School of Medicine, University of Washington School of Medicine, Stanford University |
Cohen is an American physician and geneticist whose research has focused on the biology of bacterial plasmids, independent circular units of DNA found in and sometimes exchanged by bacteria. In 1970 he found a way to make Escherichia coli acquire a plasmid that made it resistant to the antibiotic tetracycline. He also discovered with Herbert Boyer a restriction enzyme that could cleave a circular plasmid at a single site. This laid the foundation for their joint experiment in 1973 which demonstrated the feasibility of combining and replicating genetic information from different species. Their experiment involved inserted a gene for frog ribosomal RNA into bacterial cells which then expressed the gene. Three patents were taken out on their technique. These paved the way to the rise of new start-up biotechnology companies, founded on the back of the promise of genetic engineering for generating new therapeutic products. 1935-06-30T00:00:00+0000| 30 Jun 1935 | | Stanley Norman Cohen was born in Perth Amboy, NJ, USACohen | Stanford University |

Levy is an oncologist who in 1981 made history by successfully using monoclonal antibodies to treat the first patient with lymphoma. This work laid the foundation for the development of Rituxan, the first monoclonal antibody drug approved by the FDA for the treatment of cancer. Levy is now focused on the development of cancer vaccines. 1941-12-06T00:00:00+0000| 6 Dec 1941 | | Ronald Levy was born in Carmel, California, United StatesLevy | Stanford University |
The breakthrough was made by Hubert Loring and Carlton Schwerdt. They managed to isolate the virus with 80% purity. The work enabled the team to create the first vaccine in August 1947. Schwerdt continued to improve the technique and by 1953 had managed to isolate 100% pure polio virus with Bachrach Howard, laid the foundation for Jonas Salk to create a safe vaccine in 1955. 1947-01-10T00:00:00+0000| 10 Jan 1947 | | First time polio virus was isolatedLoring, Schwerdt | Stanford University |
Kornberg is a biochemist whose research is focused on working out the mechanism and regulation of transcription, which is the first step in the pathway of gene expression. In 2006 he won the Nobel Prize for working out the protein pathway that a cell's genetic information takes when transferred to a new cell. He showed how information is carried from the genes and converted to molecules called messenger ribonucleic acid (RNA). This he worked out by mapping out the process in yeast. Kornberg was the first to work out how transcription works at a molecular level in eukaryotes, a group of organisms, including humans, whose cells have a well-defined nucleus. 1947-04-24T00:00:00+0000| 24 Apr 1947 | | Roger D Kornberg was born in St. Louis, MO, USAKornberg | Stanford University |
A biochemist and cell biologist by training, Rothman was awarded the Nobel Prize in Physiology or Medicine in 2013. He received the Prize for helping to show how vesicles - small sac-like structures inside cells that carry hormones, growth factors and other molecules- determine when they have reached their correct destination to release their contents. This mechanism is vital to many key physiological functions, including cellular division, the secretion of hormones like insulin, communication between nerve cells in the brain and nutrient uptake. When this process breaks down it can lead to conditions like diabetes and botulism.

Fire is a biologist, pathologist and geneticist. In 1998 he and other colleagues working at Carnegie Institute reported in an article in Nature the discovery of tiny snippets of double-stranded RNA (dsRNA) that appeared to silence specific genes which destroyed messenger RNA, a molecule involved in the production of proteins. They hypothesised that this was caused by a catalytic process. In 2006 he shared the Nobel Prize for Medicine for helping to show the mechanism that controlled the flow of genetic information. 1959-04-27T00:00:00+0000| 27 Apr 1959 | | Andrew Z Fire was born in Stanford CA, USAFire | Carnegie Institute, Johns Hopkins, Stanford University |
Mehran Goulian and Arthur Kornberg managed to assemble the genome using one strand of natural antiviral DNA. The two scientists announced their achievement to a press conference as part of an effort to increase the American public's appreciation of government funded scientific work. It, however, generated debate about whether life should be created in a test tube. The achievement was an important stepping stone to the development of recombinant DNA. 1967-12-14T00:00:00+0000| 14 Dec 1967 | | Functional, 5,000-nucleotide-long bacteriophage genome assembledGoulian, Kornberg | Stanford University, Chicao University |

The FACS instrument automatically separates cells. Its sorting mechanism relies on antibodies coupled with fluorescent tags. The FACS was first outlined in HR Hulett, WA Bonner, J Barrett, LA Herzenberg, 'Cell sorting: automated separation of mammalian cells as a function of intracellular fluorescence' Science, 166 (1969), 747–49. By 1971 the FACS could sort 5,000 cells per second. The performance of the instrument was greatly improved by the development of monoclonal antibodies which provided a standardised reagent for the machine. Between 1971 and the early 1980s the number of FACS being used in laboratories increased from half a dozen to over 500. FACS provided a critical tool for investigating cellular structures and functions, measuring processes in cells and determining how viruses infect cells. On the clinical front they provided a means of counting white blood cells, a routine test for assessing the efficacy of chemotherapy in diseases like leukaemia. 1969-11-07T00:00:00+0000| 7 Nov 1969 | | Fluorescence activated cell sorter (FACS) publishedHerzenberg, Hulett, Bonner, Barrett | Stanford University |
