mammals. Knighted in 1992, he won the

Fellow of the Royal Society since 1984, and served as the Chair of the UK government's teacher training agency

Education and early life
Follett was educated at
Bournemouth School
Bournemouth School is a boys' grammar school and co-educational sixth form in Charminster, Bournemouth, Dorset, England, for children aged 11 to 18.

biological chemistry. On graduating he undertook a
Ph.D. with Professor Hans Heller in the Department of

's group investigating
photoperiodism. Follett's research focus became on the brain pathways whereby birds (and mammals) measure day length and use its changes to regulate breeding. He became a lecturer at
Leeds University then moved with James Dodd FRS group to the
University of Bangor in 1969, then to the
University of Bristol in 1978.
He moved to
Warwick in 1993 as Vice-Chancellor.
Research programmes
Follett's studies used, as
model species, the
Japanese quail and later wild-caught
starlings. His work included the development of the first
radioimmunoassay to measure bird
luteinizing hormone (LH) in collaboration with Frank Cunningham (
Reading University) and Colin Scanes. This made it possible to measure LH in 10 microliters of
plasma

and so follow circulating hormone levels in individual birds exposed to photoperiods of many types. Using gonadectomized
quail it was possible to show unequivocally that the underlying photoperiodic response in birds (but not mammals) is driven by
brain circuits that are switched on an off by day length. It demonstrated that measuring day length involved a daily (

) rhythm in photosensitivity with the birds being responsive to light particularly 12 and 18 hours after
dawn. In other words, if light fell at these hours then the day was read as “long”, if not then it was read as “short”.
In 1978 as the Chair of
Zoology at
Bristol, his research interest included mammals, notably
sheep, and occasionally wild birds such as
albatrosses

changes as photoinduction as it occurred in real time. The first overt change when quail are exposed to a single long day is a rise in LH secretion at about hour 20. This model was applied: to show definitively the circadian nature of the photoperiodic clock and its complex properties as an oscillator, to measure (with
Russell Foster) the action spectrum for the non-retinal light receptors, and in many studies to determine the timed sequence of neural changes as induction occurred. Subsequently, Takashi Yoshimura in

used the quail to investigate these changes in molecular terms and was able to connect these into the separate discoveries that thyroid hormones play a critical role in the photoperiodic response (see below).
(b) The termination of seasonal reproduction (refractoriness):
The photoperiodic response that long days (or short days in sheep) can not only induce reproductive maturity but also end it. The
gonads suddenly collapse and this has evolved as a means of ensuring each species has an optimal but limited time to breed each year. The term refractoriness is used since the animal becomes refractory to the prevailing photoperiod. The Bristol group found, quite counterintuitively, that
thyroid hormones are critical for refractoriness to develop and be maintained. This had been tentatively suggested in the
Soviet Union prior to
WWII but was developed by Trevor Nicholls, Arthur Goldsmith and Alistair Dawson. In simple terms, removal of the thyroid glands stopped refractoriness developing in starlings (and other birds) as well as sheep, and the animals remained in breeding condition perpetually and were not photorefractory. Thyroid hormone replacement reinstates the refractory state. Importantly birds are hatched in a refractory state but this is ended by removing the thyroid glands (per Tony Williams). The research group published papers on the concept which has become established in the understanding of the photoneuroendocrine pathway.

Secretary of the
Royal Society from 1978 until 1993. He then served for eight years as Vice-Chancellor of the
University of Warwick.
He was the founding Chair of the
Arts and Humanities Research Council (2001-2009).
[James Herbert, ''Creating the AHRC'' (Oxford, UK: Oxford University Press, 2008) 100.] He also chaired the government's Teacher Training Agency (TTA) and its successor body the Training and Development Agency for Schools (TDA) from 2004-2010.
For sixteen years, Follett was a
visiting Professor in Zoology at
Oxford University, teaching environmental physiology to undergraduates.
Follett was appointed to the Council of the AFRC/BBSRC and then to the UFC (
Universities Funding Council) and its subsequent body -

Trustee of the
Natural History Museum. He was elected to the
Royal Society in 1984 and volunteered as the Biological Secretary for six years, making changes to the organisation and extending the Royal Society University Fellowship scheme. He was knighted in 1992.
In 1992 he was appointed to the Vice-Chancellorship at the University of Warwick and led it from 1993 until 2001. The University improved its ranking in the published league tables with strengths in Engineering (Warwick Manufacturing Group), Mathematics, Economics, Sociology and the Humanities. The Warwick Research Fellowships began as an annual £10m scheme in 1994, to attract the brightest young researchers in the UK and abroad. Success was seen in the Research Assessment Exercises of 1996 and 2001. £100m of capital building was undertaken. Warwick is a founding member of the
Russell Group. It opened a graduate-entry medical school in 2001, President Clinton, with Prime Minister Blair, visited the university and gave a valedictory speech on foreign policy.
Follett has chaired committees for the UK government including reporting on the future of university libraries, research in the humanities, and the
foot-and-mouth outbreak of 2001; and on the management and appraisal of clinical academics (following the
AlderHey scandal).
Once retired, he took on the role of Chair of the Arts and Humanities Research Council (2001-2009,
and chaired the government's Teacher Training Agency (TTA) and its successor body the Training and Development Agency for Schools (TDA) from 2004-2010. It aimed to resolve teacher training recruitment and to develop the concept of the teaching assistant. Follett is a non-stipendiary visiting Professor in the Department of Zoology,
University of Oxford (2001-2019) teaching physiology to undergraduates. He was a Governor of the
Royal Shakespeare Theatre (2008-2018), and is President of the Stratford Civic Society.
Honours
* Elected to the Royal Society in 1984.
* Knighted in 1992.
* Awarded 13 honorary
doctorates and other awards.
Personal life
Follet married Deb Booth, a teacher in 1961, who later worked with radio and as the production editor for the journals of the
Society for Endocrinology. Their daughter Karen Williams is at BC Women's Hospital in
Vancouver and son Richard Follett is on the faculty at the
University of Sussex.
