1849 Obituary 
Mr. Thomas Hopkins was a grandson of the late Evan Hopkins, who was engaged in South Wales, during the last century, in the construction of canals, tram roads, and other works.
He was the second son of the late Roger Hopkins, for many years a Member of this Institution, and who was one of the early railway Engineers, having constructed the tram road near Merthyr-Tydvil, on which the first railway locomotive engine was tried by Trevithick, in the year 1804; he was also the engineer of numerous railways, canals, tram roads, bridges, and other public works in various parts of England and Wales.
Mr. Thomas Hopkins was brought up under his Father's instruction as an engineer, and afterwards entered into partnership with him and with his elder Brother, Rice Hopkins (M.Inst.C. E.). they jointly superintended the formation of railways and other works in the West of England and in South Wales. They also erected the Victoria Iron Works in Monmouthshire, and were, for several years, Directors of that undertaking.
In the years 1845 and 1846 he was engaged with his Brother in the preparation of plans, sections, and estimates for several proposed railways; but in 1817, on his health failing, he travelled under medical advice to Rome, where he died on the 8th of February, 1848, in his 39th year.
He was elected a Member of the Institution in 1836, and contributed descriptions of several works, which had been erected under his superintendence.
