Biography of Edgar Ferdinand Cyriax

Edgar Ferdinand Cyriax was born in 1874 and was originally Swedish. He was the son-in-law of Jonas Henrik Kellgren (1837-1916) who was an important figure in the late-nineteenth century spread of Swedish remedial gymnastics and massage to other parts of Europe.

Like Kellgren, Cyriax based himself in London, where in addition to practising he studied the bibliography and history of manipulative treatment. He lectured in physiology at the Central Institute for Swedish Gymnastics, London. At his death in 1955 he left a large collection of books, pamphlets and papers on the subject.

His son was Dr. James H. Cyriax (1904-1985) who coined the term orthopaedic medicine.
