Leslie Barnett (born 12 October 1920 as Margaret Leslie Collard – died 10 February 2002)[1] was a British biologist who worked with Francis Crick, Sydney Brenner, and Richard J. Watts-Tobin to genetically demonstrate the triplet nature of the code of protein translation through the Crick, Brenner, Barnett, Watts-Tobin et al. experiment of 1961, which discovered frameshift mutations; this insight provided early elucidation of the nature of the genetic code.
In her professional life, Barnett was a microbiologist who joined the
Career
Early career
At the beginning of the Second World War, she had started training in the Institute of Agriculture in Essex; but in 1939 took a job in
Barnett came to work as a technician in the MRC Unit
On Brenner's retirement in 1986, Barnett left the LMB to work for him in the new MRC Molecular Genetics Unit in Addenbrooke's Hospital. She trained the late Francis Crick in experimental work on phage and assisted him.
Barnett also helped set up Sydney Brenner's laboratory in Singapore, many years later.
Later career
Barnett was amongst the early Fellows elected to join Clare Hall, the newly founded graduate college. In 1972, she became a tutor for graduate students; in 1975, she took over the leading role of Senior Tutor, which she held until her retirement in 1985. She was remembered by hundreds of students of various nationalities, ages and subjects for her "steadfast care, wisdom in solving their problems, and motherly love."[2]
Barnett played a leading role in college affairs, particularly in the organising of social events and parties and will be remembered with great affection by her colleagues and other friends associated with the college. As a token of her contribution to the college the Governing Body has named a student residence the Leslie Barnett House, and a bronze head by the late Lois Tilbrook represents another tribute to her on the site. On retirement she was elected to an Emeritus Fellowship and attended regularly until her last illness.[2]
Tributes
Eric Miller, who was a visiting scientist at the Molecular Biology Laboratory in 1986–87, wrote: "Leslie Barnett should be recognised for her immense scientific contributions to the field of gene structure and function. Professionally, to which I am sure Francis Crick and Sydney Brenner will attest, many of the seminal discoveries in molecular biology would not have occurred without the careful hand, watchful eye and steadfast focus that Leslie brought to the bench and experiments." Francis Crick said: "Alex Rich and I engaged Leslie in 1955 to do some x-ray calculations for us, since in those days electronic computers were still very primitive. After we discovered that Leslie had biological qualifications she did various types of experimental work. Among other things she worked with us on the phase-shift mutants of phage T4. She was invaluable, as she was always such a careful and meticulous experimentalist."[2]

Recognition
In 1978 at Clare Hall a second neighbouring house in Cambridge, now called Leslie Barnett House, was obtained for graduate student accommodation; it was named after the popular Senior Tutor.
