Early life
Early life
Thomas Thomas was born in 1817 and brought up near Ffairfach, at Llandeilo, Carmarthenshire. His father ran a carpentry business, where Thomas worked before moving to Swansea.
Religious ministry
Religious ministry
Though he had no formal training he was appointed as a chapel minister in Clydach in 1848, a post which he held until 1853. Reverend Thomas subsequently became a Congregational minister at Landore, Swansea, until he resigned in 1875. It has been conjectured that he resigned after it was discovered he was the owner of sub-standard workers housing in north Swansea.
Architecture
Architecture
Thomas was also known an architect and began designing chapels in 1848 and continued through the chapel-building boom of the 1860s and '70s, designing not only for his own Congregational denomination but for others too. He had redesigned Landore's own Siloh Chapel in 1860. The New Siloh Chapel (1878) in Landore was, however, designed after Thomas's resignation by Thomas Freeman who had been a builder and surveyor of the Reverend Thomas's earlier chapels. Thomas Thomas is credited with at least 119 chapels across Wales. He also made sure he garnered the distinction of preaching the first sermon (or one of the first sermons) at each of his new chapels. His trademark design feature of chapels was the giant arch in the pediment on the facade of his buildings. He also invented the stylistic interior feature of dipping the chapel gallery behind the preacher's pulpit.
Later life
Later life
After resigning as a church minister, Thomas moved to Mumbles. He died there on 16 March 1888 and was buried at Sketty.
