1857 February 28th. Born at Norton-sub-Hamdon, Somerset, the son of Henry Gundry Sturmey, a master mariner and merchant navy captain, and his wife, Mary Ann Trask.
He was educated at Melcombe Regis School and Weymouth College.
Originally a schoolmaster. First post was as assistant master at Brixton Hill College
Left Brixton Hill in 1877.
After Sturmey had published the first edition of the ‘Indispensable’ Bicyclist's Handbook (1877), he established contact with William Iliffe, of a Coventry family printing firm Iliffe and Sons, a meeting which was to be a significant event for both. Presumably led to formation of Iliffe, Sons and Sturmey. Formed The Cyclist publication
1889 Editor of Photography magazine
1889 Participated in a meeting to form a Photographic Trades Section of the London Chamber of Commerce
1895 First editor of The Autocar magazine until 1901.
Sturmey invested heavily in the Great Horseless Carriage Co, one of the numerous companies promoted by the inventor turned financier, Harry Lawson (1852–1925), whom Sturmey succeeded as chairman of the Daimler Motor Company.
1897 October. Set out on a 1,600 mile journey around the UK with Richard Ashley in a Daimler
1900 Article on Light Automobiles.
1900 Produced prototype Voiturette which he used to test his three-speed epicyclic gearbox. The car was never put into production but the gearbox developed into the unit widely used on bicycles.
1900 His contribution to cycling continued indirectly through the Sturmey-Archer three-speed hub gear. This device had a complex background. William Reilly's original designs were patented in the name of a colleague, James Archer, to avoid a restrictive contract Reilly had entered into with the Hub Two-Speed Gear Co; this patent was 11 days before that of Henry Sturmey. It was manufactured by Frank Bowden's Three-Speed Gear Syndicate from 1903, Bowden having obtained the rights to both the Reilly/Archer and Sturmey 3-speed hubs.
In 1902 Sturmey set up the Duryea Co which built under licence in Coventry for a few years, utilizing a Rugby-made engine.
1904 STURMEY, Henry, F.R.P.S., The Quarry Close, Coventry. Cars: 3-h.p. Voiturette of his own design, 10-h.p. Duryea Surrey. Hobbies: Cycling, rowing, photography, foreign travel. "To benefit my fellowmen, the industry and the City of Coventry, and to get all the fun I can out of it myself," are Mr. Sturmey's principal aims in furthering motoring. Clubs: Midland Automobile, A.C.G.B. & I. (Club Committee). 
In the 1920s Sturmey returned to the topic of cycle gears, advocating in the cycling press the hub as opposed to the bracket gear. With John Peart, a Coventry engineer, he took out a patent (118, 178 of 1922) for the first five-speed hub gear, but failed to interest a manufacturer.
1930 Sturmey never married, and died at his Coventry home, Quarry Close, St Nicholas Street, on 8 January 1930.
1930 Obituary. Died aged 72 years. Other achievements included publication of a popular book on bicycles. Became science and maths master at Brynavor Hill College, Towyn.
