Charis Ursula Frankenburg (1892-1985) was the daughter of Percy Barnett and his wife, Annie. She was born in Isleworth, London, where her father was the Principal of the Teacher Training College. She matriculated at Somerville College, Oxford in 1912 but her studies were interrupted by the outbreak of the war. She trained as a midwife in 1915 and went to work in a maternity hospital in a war zone in France. This work later qualified her for a war degree from Oxford. She married Sydney Frankenburg in 1918 and they had four children, Peter, John, Miles and Ursula. She was the author of a number of books on childcare and had a lifelong interest in improving the lives of women and children in inner-city areas. In 1926 she set up the first birth control clinic in Salford, together with Mary Stocks. She was a JP in Salford for many years, working mostly in the Juvenile Courts.
