Sir Richard Arthur Surtees Paget (1869-1955), 2nd Baronet and barrister, began the 'New Sign Language' (later 'Systematic Sign Language') for the deaf, which was aimed in particular at the teaching of children with hearing and speech problems, in 1934. It was developed by his widow Grace Paget in collaboration with Dr Pierre Gorman. The Paget Gorman Society, a charitable trust which runs courses, publishes manuals, and acts as an examining body in the use of the system, refers to it as 'Paget Gorman Signed Speech'.
