James Dewey Watson (born April 6, 1928) is an American molecular biologist, geneticist, and zoologist, best known as a co-discoverer of the structure of DNA in 1953 with Francis Crick. Watson, Crick, and Maurice Wilkins were awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material". After studies at the University of Chicago and Indiana University, he worked at the University of Cambridge's Cavendish Laboratory in England, where he first met his future collaborator and friend Francis Crick.
 

In 1956, Watson became a junior member of Harvard University's Biological Laboratories, holding this position until 1976, promoting research in molecular biology. Between 1988 and 1992, Watson was associated with the National Institutes of Health, helping to establish the Human Genome Project. Watson has written many science books, including the textbook The Molecular Biology of the Gene (1965) and his bestselling book The Double Helix (1968) about the DNA structure discovery.
 

From 1968 he served as director of Cold Spring Harbor Laboratory (CSHL) on Long Island, New York, greatly expanding its level of funding and research. At CSHL, he shifted his research emphasis to the study of cancer. In 1994, he started as president and served for 10 years. He was appointed chancellor, serving until 2007, when he resigned due to a racist comment made during an interview. 

 

Early life and education

James Watson, was born in Chicago, Illinois on April 6, 1928, as the only son of Jean Mitchell and James D. Watson, a tax collector of Scottish descent. His mother's father, Lauchlin Mitchell, a tailor, was from Glasgow, Scotland, and her mother, Lizzie Gleason, was the child of Irish parents from Tipperary. Raised Catholic, he later described himself as "an escapee from the Catholic religion." Watson said, "The luckiest thing that ever happened to me was that my father didn't believe in God." His sister was Elizabeth Jean Watson.
 

Watson attended public school and graduated ahead of his peers. He was fascinated with bird watching, a hobby shared with his father, so he considered majoring in ornithology Watson appeared on Quiz Kids, a popular radio show that challenged bright youngsters to answer questions. Thanks to the liberal policy of University president Robert Hutchins, he enrolled at the University of Chicago at the age of 15. 
 

After reading Erwin Schrödinger's book What Is Life? in 1946, Watson changed his professional ambitions from the study of ornithology to genetics. Watson earned his B.S. degree in Zoology from the University of Chicago in 1947. In his autobiography, Avoid Boring People, Watson describes the University of Chicago as an idyllic academic institution where he was instilled with the capacity for critical thought and an ethical compulsion not to suffer fools who impeded his search for truth, in contrast to his description of later experiences. In 1947 Watson left Hyde Park to become a graduate student at Indiana University, attracted by the presence at Bloomington of the 1946 Nobel Prize winner Hermann Joseph Muller who in crucial papers published in 1922, 1929, and in the 1930s had laid out all the basic properties of the heredity molecule that Schrödinger presented in his 1944 book. He received his PhD degree from Indiana University in 1950. 
 

Career in molecular biology

Originally, Watson was drawn into molecular biology by the work of Salvador Luria. Luria eventually shared a Nobel Prize for his work on the Luria-Delbrück experiment, which concerned the nature of genetic mutations. Luria was part of a distributed group of researchers who were making use of the viruses that infect bacteria, called bacteriophages. Luria and Max Delbrück were among the leaders of this new "Phage Group", an important movement of geneticists from experimental systems such as Drosophila towards microbial genetics. Early 1948, Watson began his PhD research in Luria's laboratory at Indiana University. That spring he met Delbrück first in Luria's apartment and again that summer during Watson's first trip to the Cold Spring Harbor Laboratory (CSHL). 
 

The Phage Group was the intellectual medium where Watson became a working scientist. Importantly, the members of the Phage Group sensed that they were on the path to discovering the physical nature of the gene. In 1949 Watson took a course with Felix Haurowitz that included the conventional view of that time: that genes were proteins and able to replicate themselves. The other major molecular component of chromosomes, DNA, was widely considered to be a "stupid tetranucleotide", serving only a structural role to support the proteins. However, even at this early time, Watson, under the influence of the Phage Group, was aware of the Avery-MacLeod-McCarty experiment, which suggested that DNA was the genetic molecule. Watson's research project involved using X-rays to inactivate bacterial viruses. He gained his PhD in Zoology at Indiana University in 1950 (at age 22).
 

Watson then went to Copenhagen University in September 1950 for a year of postdoctoral research, first heading to the laboratory of biochemist Herman Kalckar. Kalckar was interested in the enzymatic synthesis of nucleic acids, and he wanted to use phages as an experimental system. Watson, however, wanted to explore the structure of DNA, and his interests did not coincide with Kalckar's. After working part of the year with Kalcker, Watson spent the remainder of his time in Copenhagen conducting experiments with microbial physiologist Ole Maaloe, then a member of the Phage Group. 
 

The experiments, which Watson had learned of during the previous summer's Cold Spring Harbor phage conference, included the use of radioactive phosphate as a tracer to determine which molecular components of phage particles actually infect the target bacteria during viral infection. The intention was to determine whether protein or DNA was the genetic material, but upon consultation with Max Delbrück, they determined that their results were inconclusive and could not specifically identify the newly labeled molecules as DNA. Watson never developed a constructive interaction with Kalckar, but he did accompany Kalckar to a meeting in Italy where Watson saw Maurice Wilkins talk about his X-ray diffraction data for DNA. Watson was now certain that DNA had a definite molecular structure that could be elucidated. 
 

In 1951, the chemist Linus Pauling in California published his model of the amino acid alpha helix, a result that grew out of Pauling's efforts in X-ray crystallography and molecular model building. After obtaining some results from his phage and other experimental research conducted at Indiana University, Statens Serum Institut (Denmark), Cold Spring Harbor Laboratory, and the California Institute of Technology, Watson now had the desire to learn to perform X-ray diffraction experiments so that he could work to determine the structure of DNA. That summer, Luria met John Kendrew, and he arranged for a new postdoctoral research project for Watson in England. 
 

Double helix

In March 1953, Watson and Crick deduced the double helix structure of DNA. Sir Lawrence Bragg, the director of the Cavendish Laboratory (where Watson and Crick worked), made the original announcement of the discovery at a Solvay conference on proteins in Belgium on April 8, 1953; it went unreported by the press. Watson and Crick submitted a paper to the scientific journal Nature, which was published on April 25, 1953. This has been described by some other biologists and Nobel laureates as the most important scientific discovery of the 20th century. Bragg gave a talk at the Guys Hospital Medical School in London on Thursday, May 14, 1953, which resulted in an article by Ritchie Calder in the newspaper The News Chronicle of London, on May 15, 1953, entitled "Why You Are You. Nearer Secret of Life."
 

Sydney Brenner, Jack Dunitz, Dorothy Hodgkin, Leslie Orgel, and Beryl M. Oughton, were some of the first people in April 1953 to see the model of the structure of DNA, constructed by Crick and Watson; at the time they were working at Oxford University's Chemistry Department. All were impressed by the new DNA model, especially Brenner who subsequently worked with Crick at Cambridge in the Cavendish Laboratory and the new Laboratory of Molecular Biology. 
 

The Cambridge University student newspaper Varsity also ran its own short article on the discovery on Saturday, May 30, 1953. Watson subsequently presented a paper on the double helical structure of DNA at the 18th Cold Spring Harbor Symposium on Viruses in early June 1953, six weeks after the publication of the Watson & Crick paper in "Nature". Many at the meeting had not yet heard of the discovery. The 1953 Cold Harbor Symposium was the first opportunity for many to see the model of the DNA Double Helix. Watson claimed that he was refused a $1,000 raise in salary after winning the Nobel Prize. Watson, Crick, and Wilkins were awarded the Nobel Prize in Physiology or Medicine in 1962 for their research on the structure of nucleic acids. 

 

At Harvard University, starting in 1956, Watson achieved a series of academic promotions from Assistant Professor, to Associate Professor to full Professor of Biology. He championed a switch in focus for the school from classical biology to molecular biology, stating that disciplines such as ecology, developmental biology, taxonomy, physiology, etc. had stagnated and could only progress once the underlying disciplines of molecular biology and biochemistry had elucidated their underpinnings, going so far as to discourage their study by students. He left the school in 1976.
 

Later career

In 1968, Watson became the Director of the Cold Spring Harbor Laboratory. Between 1970 and 1972, the Watsons' two sons were born, and by 1974 the young family made Cold Spring Harbor their permanent residence. Watson served as the Laboratory's Director and president for about 35 years, and later he assumed the role of Chancellor. In October 2007, Watson resigned as a result of controversial remark about race made to the press. In a retrospective summary of his accomplishments there, Bruce Stillman, the laboratory's president said, "Jim Watson created a research environment that is unparalleled in the world of science." It was "under his direction [that the Lab has] made major contributions to understanding the genetic basis of cancer."
 

Generally in his roles as Director, President, and Chancellor, Watson led CSHL to its present day mission, which is "dedicat[ion] to exploring molecular biology and genetics in order to advance the understanding and ability to diagnose and treat cancers, neurological diseases, and other causes of human suffering." In October 2007, Watson was suspended following criticism of views on race and intelligence attributed to him, and a week later, on the 25th, he retired at the age of 79 from Cold Spring Harbor Laboratory from what the lab called "nearly 40 years of distinguished service", In a statement, Watson attributed his retirement to his age, and circumstances that he could never have anticipated or desired. 
 

In January 2007, Watson accepted the invitation of Leonor Beleza, president of the Champalimaud Foundation, to become the head of the foundation's scientific council, an advisory organ. He will be in charge of selecting the remaining council members. 
 

Watson was a former member of the Board of Directors of United Biomedical, Inc founded by Chang Yi Wang. He held the position for 6 years and retired from the Board in 1999. Watson was also a former adviser for the Allen Institute for Brain Science. The Allen Institute, located in Seattle, Washington, was founded in 2003 by Philanthropists Paul G. Allen and Jody Allen as a 501(c)(3) nonprofit corporation medical research organization. A multidisciplinary group of neuroscientists, molecular biologists, informaticists, engineers, mathematicians, statisticians, and computational biologists were brought together to form the scientific core of the Allen Institute. Utilizing the mouse model system, these fields have joined together to investigate expression of 20,000 genes in the adult mouse brain and to map gene expression to a cellular level beyond neuroanatomic boundaries. The data generated from this joint effort is contained in the publicly available Allen Mouse Brain Atlas. Upon completion of the Allen Mouse Brain Atlas, this consortium of scientists will pursue additional questions to further our understanding of neuronal circuitry and the neuroanatomic framework that defines the functionality of the brain.
 

The Double Helix

In 1968, Watson wrote The Double Helix, one of the Modern Library's 100 Best Nonfiction books. The book details the sometimes painful story of not only the discovery of the structure of DNA, but also the personalities, conflicts and controversy surrounding their work. Watson's original title was to have been "Honest Jim", in that the book recounts the discovery of the double helix from his point of view and included many of his private emotional impressions at the time. The book changed the way the public viewed scientists and the way they work. 
 

Some controversy surrounded the publication of the book. Watson's book was originally to be published by the Harvard University Press, but both Francis Crick and Maurice Wilkins objected, among others. Watson's home university dropped the project and the book was commercially published. 
 

Watson's first textbook, The Molecular Biology of the Gene, set a new standard for textbooks, particularly through the use of concept heads—brief declarative subheadings. Its style has been emulated by almost all successive textbooks. His next textbook was Molecular Biology of the Cell, in which he coordinated the work of a group of scientist-writers. His third textbook was Recombinant DNA, which described the ways in which genetic engineering has brought much new information about how organisms function. The textbooks are still in print.
 

Human genome project

In 1990, Watson was appointed as the Head of the Human Genome Project at the National Institutes of Health, a position he held until April 10, 1992. Watson left the Genome Project after conflicts with the new NIH Director, Bernadine Healy. Watson was opposed to Healy's attempts to acquire patents on gene sequences, and any ownership of the "laws of nature." Two years before stepping down from the Genome Project, he had stated his own opinion on this long and ongoing controversy which he saw as an illogical barrier to research; he said, "The nations of the world must see that the human genome belongs to the world's people, as opposed to its nations." He left within weeks of the 1992 announcement that the NIH would be applying for patents on brain-specific cDNAs. (The issue of the patentability of genes is still not resolved in the US; see Association for Molecular Pathology v. U.S. Patent and Trademark Office)

In 1994, Watson became President of CSHL. Francis Collins took over the role as Director of the Human Genome Project.
 

In 2007, James Watson became the second personto publish his fully sequenced genome online, after it was presented to him on May 31, 2007 by 454 Life Sciences Corporation in collaboration with scientists at the Human Genome Sequencing Center, Baylor College of Medicine. Watson was quoted as saying, "I am putting my genome sequence on line to encourage the development of an era of personalized medicine, in which information contained in our genomes can be used to identify and prevent disease and to create individualized medical therapies".
 

Political activism

During his tenure as a professor at Harvard, Watson participated in several political protests:
 

• Vietnam War: While a professor at Harvard University, Watson, along with "12 Faculty members of the department of Biochemistry and Molecular Biology" including one other Nobel prize winner, spearheaded a resolution for "the immediate withdrawal of U.S. forces' from Vietnam." 

• Nuclear proliferation and environmentalism: In 1975, on the "thirtieth anniversary of the bombing of Hiroshima," Watson along with "over 2000 scientists and engineers" spoke out against nuclear proliferation to President Ford in part because of the "lack of a proven method for the ultimate disposal of radioactive waste" and because "The writers of the declaration see the proliferation of nuclear plants as a major threat to American liberties and international safety because they say safeguard procedures are inadequate to prevent terrorist theft of commercial reactor-produced plutonium." 

• In recent years, Watson has stated: "I turned against the left wing because they don't like genetics, because genetics implies that sometimes in life we fail because we have bad genes. They want all failure in life to be due to the evil system."
