Mortimer was born on 22 July 1805 at Bishopsteignton in Devonshire, was the eldest son of William Mortimer, a country gentleman of that place.
Balliol College.
He was educated at the Exeter grammar school and at Balliol College, Oxford, where he matriculated 18 March 1823, and obtained an exhibition. Thence he migrated to Queen"s, where he secured a Michel exhibition, and was placed in the first class of the final classical school at Michaelmas 1826 with the future archdeacon of Taunton, George Anthony Denison, and another. After graduating Bachelor of Arts in 1826 he engaged actively in tuition.
He proceeded Master of Arts in 1829, and Doctor of Divinity in 1841, having been ordained on 24 February 1829.
He was successively head-master of the Royal Grammar School, Newcastle (from 1828) and of the Western proprietary school at Brompton, London (from 1833). In 1840 he was appointed, in succession to John Allen Giles, to the scene of his longest and most important labours, the headship of the City of London School.
The school had been opened in 1837, but its prosperity had been injured by the action of the first head-master. Mortimer"s administrative ability and genial manner rendered the success of the school certain.
In 1861 he had the unique distinction of seeing two of his scholars respectively senior wrangler and senior classic at Cambridge.
Charles Kingsley read privately with him for ordination. Doctor Mortimer received in 1864 the honorary prebend of Consumpta per mare in Saint Paul"s, and for many years was evening lecturer at Saint Matthew"s, Friday Street. At Michaelmas 1865 he resigned his head-mastership, and for the next few years interested himself actively in the Society of Schoolmasters and other educational institutions.
He died 7 September
1871, at Rose Hill, Hampton Wick, and was buried in Hampton churchyard. Besides two sermons, Mortimer published while at Newcastle a pamphlet entitled "The Immediate Abolition of Slavery compatible with the Safety and Prosperity of the Colonies".
