Brigadier-General Sir Henry Percy Maybury (17 November 1864 – 7 January 1943) was a British civil engineer. He began his career as a railway engineer, working on many railways in England and Wales before becoming the county surveyor for Kent. At the start of the First World War he was appointed to supervise roads used by the Allies in France, holding the British Army rank of Brigadier-General. In recognition of his services in this theatre he was appointed a Companion of the Order of the Bath and a Knight Commander of the Order of St Michael and St George by the British government and an officer of the Legion of Honour by the French. After the war he held various civil service positions, mainly within the Ministry of Transport, and was elected president of the Institution of Civil Engineers in 1933. Early life Maybury was born in Uffington in Shropshire, fourth son of Charles Maybury, a farmer, and his wife Jane (nee Matthews), and was educated at nearby Upton Magna. Upon finishing his studies Maybury began work at Shrewsbury railway station in the office of RE Johnston, the chief engineer of the Shrewsbury and Hereford Railway, a joint venture between the Great Western and London and North Western railway companies, where he worked for five years. In 1884 he joined the Wrexham contracting firm of Johnson Brothers and Slay, where he became manager, and worked on the Glyn Valley Tramway during the rebuilding in 1886. From 1892 until 1895 he served as the engineer and surveyor of the Ffestiniog Local Highways Board, followed by a similar appointment to the Malvern Urban District Council. From 1904 until 1913 Maybury served as the county surveyor for Kent during which time he was responsible for constructing new roads and classifying the existing network in light of the rapid increase in motor traffic following the revised speed limits of the Motor Car Act 1903. He carried out experiments on road surfaces at Sidcup to try to improve durability and reduce dust produced by the increased speed of traffic. In 1904 he also developed sewerage and drinking water schemes for Ludlow County Borough and Worcestershire County Council. In 1910 he was invited to become a member of the Advisory Engineering Committee to the Roads Board, who had been impressed by his road surface trials, and served as their chief engineering officer upon leaving his position
