Thomas Casson (1845-1912) was the son of Samuel, a clothier, and his wife, Mary. Thomas apparently first worked as an iron moulder. By 1871, he was a pearl grinder and three years later established a pearl handle and scale cutting business at 188 Rockingham Street. Casson was featured in the vanity publication, The Century’s Progress (1893), but his vapid profile provides little information, apart from the fact that he exported chiefly to the Continent. Casson lived in Crookesmoor and had retired by 1911. He died on 7 May 1912, leaving £3,623. His burial was in Fulwood.
