After education at St Paul's School, London, George Graham matriculated at Trinity College, Cambridge, where he graduated BA in 1904.
After studying medicine at St Bartholomew's Hospital and qualifying MRCS, LRCP in 1907,[3] he graduated from the University of Cambridge with MB BChir in 1908 and MD in 1912.
Supported by a Beit Memorial Fellowship, he worked from 1912 to 1914 at the Institute of Physiology in Munich on the protein-sparing action of carbohydrates.
In 1920 he was elected FRCP and began working at St Bartholomew Hospital's newly established medical professorial unit, which was directed by Francis Fraser after Sir Archibald Garrod went to Oxford.
This system has many adherents; it is easy of application and yields briilliant results, especially in those milder cases tolerating high protein-fat allowances and reacting badly only to carbohydrates.
