Abraham Dyson was apparently born in Sheffield on 28 April 1807, the son of Abraham (a whitesmith) and Hannah. In 1833, Dyson Jun. was listed as a dessert-knife haft fluter in Charles Street. In 1835, he registered a silver mark as a plate worker and henceforth listed himself as a maker of silver dessert and fruit knives. His advertisements appeared in a Sheffield directory (1839) and Drake’s Roadbook (1840).  Abraham Dyson was bankrupt in 1841 and the next year took his family to America, where he settled in St Louis as a butcher (and later an inspector of pork).  He had retired by 1880 and he died in St Louis in February 1884.
