Grace Frankland

Grace Coleridge Frankland née Grace Toynbee (4 December 1858 – 5 October 1946) was an English microbiologist. She was the daughter of Harriet and Joseph Toynbee, a noted otologist. She married Percy Frankland in 1882, and with him developed an interest in the emerging science of bacteriology. She worked with both Percy and his father Edward Frankland and was described at the time as having "worthily aided and seconded [Percy]". She co-authored papers with her husband on bacteria and other microorganisms found in the air and water.
In 1903 she wrote a popular science book entitled Bacteria in Daily Life. She was a Fellow of the Royal Microscopical Society, admitted into the Linnean Society of London, and an honorary member of Bedford College.
