Thomas Thomas known by his Welsh surname Aptommas (1829-1913) was a Welsh harpist and composer-arranger.
He was born in Bridgend, a younger brother of the more famous John Thomas (Pencerdd Gwalia).[1] He performed in America with Louis Moreau Gottschalk and Henriette Behrend.[2] Even when playing the pedal harp, Thomas kept the instrument on his left shoulder, as did traditional Welsh harpists. Harp-maker Erard had to construct special harps with the mechanisms reversed for him.[3]
