Frankland left London in 1888 to become Professor of Chemistry at Dundee, where his main scientific interests were in stereochemistry and in the preparation of pure cultures of bacilli, which were allowed to grow in solutions of sugars. Together with his wife, Grace Frankland, they isolated the first pure culture of nitrifying (ammonia-oxidizing) bacterium in 1890.[7]
He then went to Birmingham in 1894 as Professor of what was then Mason College, where he succeeded Professor William A. Tilden. Frankland retired at the end of the First World War, aged 60. A list of his publications, from 1880-1920 is included in the Royal Society memoir.[1]
In 1882, Frankland married Grace (née Toynbee), the daughter of Joseph Toynbee. She worked with both Percy and his father and was described at the time as having "worthily aided and seconded [Percy]".[9] The couple co-authored papers on bacteria and other microorganisms found in the air[10] and water.[11]
They lived at Grove House, Pembridge Square, London.[12] Their only child, Edward Percy, was born in 1884. He married Maud Metcalfe-Gibson in 1915. The couple had two sons and a daughter: the parasitologist Helga Maud Toynbee Frankland,[13] who wrote about her grandfather Percy and other family members.[14]
