A historian, born at Nottingham on 25 January 1838, was the son of Edgar Sanderson and his wife, Eliza Rumsey. His father, a direct descendant of Bishop Robert Sanderson, was a lace manufacturer at Nottingham, who later kept private schools in London at Stockwell and Streatham. Sanderson was educated at the City of London School and at Clare College, Cambridge. After graduating in 1860 in the second class of the classical tripos he was ordained deacon in 1862 and priest in 1863. He married in 1864 Laetitia Jane (d. Oct 1894), elder daughter of Matthew Denycloe, a surgeon of Bridport; they had two sons and four daughters. Between 1870 and 1881 he was successively headmaster of Stockwell, Macclesfield, and Huntingdon grammar schools.
Thenceforth he lived at Streatham Common, and occupied himself in writing educational manuals and popular historical works. Sanderson's digests of world history enjoyed a wide circulation, and his History of the British Empire (1882) went into twenty editions in his lifetime. He died at his home, 23 Barrow Road, Streatham Common, on 31 December 1907 and is buried at West Norwood Cemetery
