We are sad to report the passing of Katherine Whitwell, who has died aged 83.
Katherine was an internationally respected veterinary pathologist whose work over five decades transformed understanding of equine disease. Her decades of consultancy for Beaufort Cottage Laboratories (now Rossdales Laboratories) made her an indispensable source of guidance for our clinicians and diagnosticians alike and she will be much missed.

Katherine Elsa Whitwell, BVSc, DipECVP, FRCVS, (b) 1942, (q) Liverpool 1965. Died 3 August 2025
BORN in 1942, the daughter of a medical pathologist and a watercolour artist, Katherine grew up in Heswall on the Wirral peninsula and studied at the University of Liverpool, graduating in veterinary science (BVSc) in 1965.
Katherine’s first job after graduation was in a large mixed farm and equine practice in Montgomery, mid-Wales, where her first boss, Terry Boundy, was impressed by her introduction to the practice of the then novel therapy of intravenous fluid treatment for scouring calves.
Perhaps following in her father’s footsteps, Katherine quickly developed a passion for veterinary pathology, moving to Newmarket from Montgomery to pursue her interest in horses. Her career was distinguished by national and international recognition: she became an RCVS fellow in 1985 and was among the first diplomates of the European College of Veterinary Pathologists in 1997. For many years she remained the only RCVS-recognised Specialist in equine pathology.
At the Animal Health Trust (AHT), Katherine dedicated her professional life to advancing equine health. Her research spanned equine grass sickness, wobbler syndrome, umbilical cord torsion, equine forensics and palaeopathology, among other areas. She was a prolific author and a sought-after speaker at national and international meetings. Her curiosity and talent for collaboration with clinicians, epidemiologists, immunologists, microbiologists and fellow pathologists were instrumental in shaping the AHT’s reputation as a world-class institution. Working closely with Katherine at that time were a number of colleagues, including Hugh Platt, Leo Jeffcott, Tony Blunden, Ken Smith, Duncan Hannant, James Wood, Richard Newton, Julia Kydd and the late Jenny Mumford.
Katherine’s contributions to equine diagnostics were pivotal. She provided numerous postmortem examinations and biopsy assessments for Greenwood, Ellis and Partners (now the Newmarket Equine Hospital). Colleagues Richard Greenwood and David Ellis recall her commitment: ‘No case was too complex and Katherine’s conclusions were always expressed with clarity and practicality.’ Similarly, her decades of consultancy for Beaufort Cottage Laboratories (now Rossdales Laboratories) made her an indispensable source of guidance for clinicians and diagnosticians alike. Sidney Ricketts, Annalisa Barrelet and Alastair Foote, among many others, valued her encyclopaedic knowledge, attention to detail and ability to think laterally about clinical problems.
Katherine was passionate about training the next generation of veterinary pathologists. Many young vets remember her patient mentorship, her infectious enthusiasm and her determination to ensure that knowledge was freely shared.
Colleagues also recall her distinctive wit and sharp eye. At an international equine infectious diseases conference in Lexington, Kentucky, USA, she interrupted the conference president’s opening address to point out – accurately – that the third cervical vertebra in the full-size skeleton of eohippus (a long-extinct ancestor of the modern horse) was the wrong way round. The hall erupted in laughter, and the chastened president promised immediate correction. It was a moment that perfectly captured Katherine’s combination of authority, humour and uncompromising attention to detail.
Katherine’s work on equine grass sickness exemplified her powers of observation. With her deep knowledge of the Suffolk countryside, she noticed that pastures associated with the disease also contained unusual numbers of sick or dead wild hares. She went on to identify that hares suffered a parallel disorder (which she named leporine dysautonomia), a discovery that suggested that wild hares might serve as sentinel animals for affected land. This ‘Miss Marple’ quality – her ability to notice overlooked details and connect them with scientific insight – was characteristic of her approach.
Katherine’s devotion to animals was not confined to her professional life. She surrounded herself with animals at home, including her much-loved Soay sheep (the escapes of which presented a regular happy challenge) and her ever-present cats. Friends recall a household that was lively, sometimes chaotic, but always joyful.
In retirement Katherine remained active, especially in the village of Moulton where she had lived for over 50 years, and regularly attended veterinary meetings, where her experience was highly valued. It is especially touching that seven weeks before her passing she was able to attend the Class of 1965 reunion at the Liverpool veterinary school, joining the tour of the current veterinary school facilities with her usual curiosity and enthusiasm, despite her failing health.
Katherine passed away peacefully at home on 3 August 2025 and her funeral was held in St Peter’s Church, Moulton, on 28 August, when friends and colleagues paid tribute to a wonderful human being.
As Annalisa Barrelet said: ‘Katherine lived life with a generosity of spirit, she gave her time and knowledge freely and she cared deeply for those around her – human and animal alike.’
