My oldest son
probably knew about My Very Important Peron (VIP) for this week is James Dewey Watson years ago. My son majored in molecular
biology, and Watson is a molecular biologist, geneticist and zoologist. He is best known for being co-discoverer
structure of DNA in 1953 with Francis Crick.
Watson and Crick, along with Maurice Wilkins, received the Nobel Prize
in Physiology or Medicine in 1962. Their
award was “for their discoveries concerning the molecular structure of nucleic
acids and its significance for information transfer in living material.”
Watson was born on April 6,
1928, in Chicago, Illinois; he is the only son of Jean (Mitchell) and James D.
Watson, a businessman whose ancestors were colonial English immigrants to
America. His maternal grandfather was
Lauchlin Mitchell who was a tailor from Glasgow, Scotland; his maternal
grandmother was Lizzie Gleason whose Irish parents were from Tipperary. He was raised Catholic who escaped from the
religion because his father did not believe in God.
Growing up on the south side of
Chicago, Watson “attended public schools, including Grammar School and South
Shore High School.” Watson and his
father were fascinated with watching birds and often shared this hobby; Watson
even considered majoring in ornithology.
Watson enrolled at the University of Chicago on a tuition scholarship
when he was only 15 years old. Robert
Hutchins, the University president, apparently heard Watson answer questions on
“Quiz Kids, a popular radio show that
challenged bright youngsters.”
Watson “changed his professional
ambitions from the study of ornithology to genetics” after reading Erwin
Schrodinger’s What Is Life? “In his autobiography, Avoid Boring People, Watson described 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 the University of Chicago
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 Schrodinger presented in his
1944 book. He received his PhD degree
from Indiana University in 1950; Salvador Luria was his doctoral advisor.”
Early in 1948, Watson began his
PhD at Indiana University and did research in the laboratory of Salvador Luria,
another Nobel Prize winner. In September
1950 began a year of postdoctoral research at Copenhagen University. He first worked with biochemist Herman
Kallckar and later worked with microbial physiologist Ole Maaloe. Watson’s intention was “to determine whether
protein or DNA was the genetic material.”
He attended a meeting in Italy where Maurice Wilkins spoke about “his
X-ray diffraction data for DNA.”
Following the presentation, Watson was “certain that DNA had a definite
molecular structure that could be elucidated.”
After chemist Linus Pauling in
California published his model of the amino acid alpha helix in 1951 and Watson
did further research, Watson wanted to “learn to perform X-ray diffraction
experiments so he could work to determine the structure of DNA.” He went to England in 1951 to do “a new
postdoctoral research project.”
In mid-March 1953 Maurice
Wilkins, Watson and Crick used their own experimental data as well as much collected
by Rosalind Franklin and “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 Guy’s Hospital Medical School in London on Thursday, May 14,
1953, which resulted in a May 15, 1953, article by Ritchie Calder in the London
newspaper News Chronicle, entitled
`Why You Are You. Nearer Secret of Life.’”
In 1962 Watson, Crick, and
Wilkins received the Nobel Prize in Physiology or Medicine for their research
on the structure of nucleic acids.
Rosalind Franklin was not eligible for nomination because she died in
1958. “The publication of the double
helix structure of DNA can be regarded as a turning point in science: human understanding of life was fundamentally
changed and the modern era of biology began.”
In 1968 Watson married Elizabeth
Lewis, and the couple became parents of two sons, Rufus Robert Watson (born
1970) and Duncan James Watson (born 1972).
Rufus suffers from schizophrenia, and Watson desires “to encourage
progress in understanding and treatment of mental illness by determining how
genetics contributes to it.” Watson is
an atheist and signed the Humanist Manifesto in 2003, along with 21 other Nobel
Laureates.
