 Turnbull was extremely forward-thinking, introducing a system of "small profits and quick returns" at a time when established drapers gave long credit.From humble beginnings, he built up his Sunderland-based business "Albion House" into one of the largest drapery houses in Northern England.At his death, it occupied "122-126 High Street West", Sunderland, and the premises included sleeping and dining accommodation for 160 assistants, plus a library of nearly 2,500 volumes for their use.
