Claire Loewenfeld

Claire Loewenfeld, born Lewisohn in Tübingen, Germany (27 September 1899 – 20  August 1974) was a nutritionist and herbalist who worked in England during and after the Second World War promoting the importance of good nutrition, most notably rosehips from Britain's hedgerows as a source of vitamin C. She studied at Maximilian Bircher-Benner's clinic in Zurich, Switzerland, and worked as a dietician at Great Ormond Street Hospital for Sick Children in London, where she developed a fruit and vegetable diet for the treatment of coeliac disease.

Loewenfeld was the founder of Chiltern Herb Farms in England, one of the earliest producers of high-quality dried herbs, and was one of the first members of the Soil Association. She wrote a number of books about nutrition, including ''Britain's Wild Larder: Fungi'' (1956), ''Herb Gardening'' (1967) and ''Everything You Should Know About Your Food'' (1978).
