Harold Orton (October 23, 1898 -- March 7, 1975) was an English university lecturer and dialectologist, best remembered as co-founder of the Survey of English Dialects (SED). Orton developed the questionnaire for the survey together with Eugen Dieth. His pupil David Parry went on to apply the same principles used for the SED to Welsh English, founding the Survey of Anglo-Welsh Dialects (SAWD) at Swansea University in 1968.
