Major-General Henry Young Darracott Scott (2 January 1822 – 16 April 1883) was a British Army officer in the Corps of Royal Engineers.
On 1 April 1855, Scott was promoted to first captain and was appointed instructor in surveying at the Royal Engineer establishment at Brompton, Chatham.
He revised the selenitic lime and his system of representing ground by horizontal hachures and a scale of shade at Chatham and adopted it for the army as the basis of military sketching.
On 14 December 1865, he was seconded in his corps and employed under the commission of the Great Exhibition of 1851 at South Kensington in the place of Captain Francis Fowke.
On 7 June 1871 he was promoted to be brevet colonel and on 19 August of the same year, he retired from the army as an honorary major-general but continued in his civil appointment at South Kensington.
He had prepared plans for the completion of the South Kensington Museum when, in 1882, the Treasury, as an economy, abolished his appointment as secretary of the Great Exhibition commissioners.
Scott married on 19 June 1851, at Woolwich to Ellen Selina, the youngest daughter of Major-General Bowes of the East India Company's service.
Henry Young Darracott Scott died at his residence, Silverdale, Sydenham, on 16 April 1883 and was buried at Highgate Cemetery.
