Dr John Saltmarsh (7 May 1908 – 25 September 1974) was a historian and Fellow of King's College, Cambridge.
The son of Winnifred and H. A. Saltmarsh, he grew up at Oakington, near Cambridge, where his father farmed four hundred acres.
He used regularly to conduct parties around it, and tell stories of specific discoveries he had made - including some about the remains of bones from the meals that masons working on the chapel had brought along with them, several hundred years earlier.
Saltmarsh retired from college teaching in 1971, fell seriously ill in 1972, and died on 25 September 1974 at sixty-six.
He was unmarried and had spent most of his life in the same rooms at King's, where he was looked on as an eccentric bachelor don.
