The Physiological Society honours Dr Elsie Widdowson with Blue Plaque Unveiling

A blue plaque, awarded by the Physiological Society, has been unveiled at King’s College Hospital on Wednesday 4 June 2025, to honour the pioneering nutritional physiologist and dietitian, Dr Elsie May Widdowson CH CBE FRS, whose ground-breaking work transformed the field of nutrition and public health.

The plaque marks the site where, in 1933, Widdowson began her influential collaboration with Dr Robert McCance in the hospital kitchens—famously challenging his carbohydrate measurements in apples. This bold moment sparked a scientific partnership that would shape the future of nutritional science.

Through documenting the nutritional content of thousands of foods, Widdowson and McCance developed the first comprehensive tables of food composition, which became the foundation for modern dietary guidelines. Their work also laid the groundwork for understanding the long-term effects of childhood nutrition on adult health.

To celebrate Widdowson’s legacy, apple cake – a nod to her early research – was served to all in-patients at King’s College Hospital as part of the hospitality menu. Apple muffins will also be available throughout the week as an alternative snack.

Guests attending the unveiling enjoyed the apple cake as one of the canapés, alongside a sparkling apple drink, adding a celebratory touch to the occasion.

Dr Mamta Shetty Vaidya, Chief Medical Officer at King’s College Hospital NHS Foundation Trust, said: “I’m honoured to help unveil this plaque celebrating Elsie’s legacy. Her pioneering work in dietetics had a profound impact on public health – yet, like so many women, her contributions have often gone unrecognised. Today’s event is a powerful reminder of the need to shine a light on the vital achievements of women throughout history. I’m proud that through the Women’s Network, we are helping to ensure these stories are seen and celebrated.”

Claire Melody, Co-Chair of the Women’s Network and Programme Manager at King’s College Hospital NHS Foundation Trust, said: “I am incredibly proud and humbled by the dedication and effort of the Women’s Network steering group and our colleagues in securing this plaque and organising such a meaningful celebration. This recognition reflects our shared commitment to empowering women and building a supportive, inclusive community. Together, we are helping to shape a more equitable future, and I am honoured to be part of that journey.”

The event also featured talks from leading physiologists and dietitians, and a networking reception. It served as a powerful reminder of the enduring impact of Widdowson’s work and the vital role of physiology in improving lives.
