Humphry Sandwith III (25 May 1792 – 25 July 1874), was an English physician and prominent Methodist.
Sandwith was born in Helmsley, Yorkshire, the son of Humphry Sandwith II (1746–1809), another medical man, and Hannah Backhouse.
The reason was that he took the chance to become the first editor of The Watchman, a new Wesleyan Methodist journal, initially published in January 1835.
He had made a reputation among Wesleyan Methodists, both as a controversialist, and as someone concerned to circulate their news.
[4] Sandwith died on 25 July 1874, at Todwick Rectory.
