Leslie R. H. Willis (13 July 1908 – 12 March 1984) was an English mechanical and electrical engineer and archaeologist, who excavated the Iron Age settlement at the hamlet of Dainton, at Ipplepen, Teignbridge, Devon in the late 1940s.
His mother was a first cousin of General Frederick Charles Maisey, who excavated the Buddhist complex of Sanchi in 1851, and was aunt of T. M. Wilkes, head of New Zealand's civil aviation in the 1930s and 1940s.
Willis was in charge of the excavation on behalf of the Devon Archaeological Exploration Society; the initial phase took three weeks in August 1949, centred on Dainton Common.
[27] Willis married the youngest daughter of a London building contractor, a relative by marriage of Sir Edward Lugard, Permanent Under-Secretary of State for War from 1861 to 1871; they had two sons.
He died in 1984 of complications from pneumonia, survived by his sons, grandsons, and his elder brother Sidney Willis, MVO, of The Old Rectory, Havering, a civil servant.
