Leah’s supplied the town’s burgeoning silver and electro-plate trade with stampings.  It originated with Henry Leah Jun., a silversmith and silver stamper, who was born in Chesterfield in about 1841.  Leah was working in Bedford Street in 1868.  In 1879, he was listed as a silver stamper in South Street, Park.  By the 1880s, he operated as a ‘general stamper’ from Shoreham Street and Bowden Street.   In 1892, Henry Leah moved into the vacant Cambridge Street Horn Works (formerly the address of horn merchant, Robert Thompson).  Henry Leah died on 25 April 1893, leaving £919.  By the turn of the century, Leah’s Yard was a hive of activity, with the premises shared with eighteen little mesters.  Henry Leah & Sons was operated by Henry’s sons, Harry Wilson Leah (1866-1939) and Louis Thomas Leah (1869-1942).  

In 1929, Leah’s was registered as a limited company (capital £11,000) and silver stamper Walter Walker & Co was absorbed.  The Leah family evidently prospered:  Harry W. Leah left £14,401, when he died in 1939 (after a service at the Christadelphian Church, he was buried at the General Cemetery).  Louis Thomas Leah left £24,238 in 1942.  However, in 1946 Leah’s capital was reduced from £11,000 to £7,000.  The family influence continued in the late 1940s, with John Henry Leah as company secretary.  By 1976, Leah’s had vacated the factory, which had become known as Cambridge Stamping Works.  In 1982, Leah-Tomkinson-Lancelott Stampings continued to operate at Sheaf Bank Works, Prospect Road, in conjunction with J. H. Dickinson.  In 2018, a £500m renovation of the derelict Leah’s Yard was announced.
