Spencer's original £300 investment had grown to a value of £15,000 () and he retired later that year. Michael Marks continued to develop the business until his death at Knoll House, 396 Bury New Road, Salford, on 31 December 1907. He was buried in the Old Jewish cemetery (Hebrew Congregation), Crumpsall, in plot number 1917, on 2 January 1908.

He introduced the "St Michael" brand name in honour of his father, which remained in use until 2000.
