The river Wandle, now a place of recreation, was once a hub of industry. For at least 1,000 years water wheels, turned by the fast moving river, powered local mills. At its height, the Wandle was termed “the hardest worked river of its size.” Over the centuries, corn and flour mills, flocking, snuff mills, copper mills, paper and card mills, lined the river. One of the last paper mills was Merton Board Mills, which closed in 1985. The bleaching, dyeing and printing of fabrics, tapestry, weaving and felt making, made this river the cradle of the textile industry. With the advent of steam engines, the textile industry migrated north. There was also leather tanning, processing and working. Connolly’s leather mill stood on a site occupied by mills for 750 years. It produced the coloured leather covering the seats of the House of Commons and the House of Lords. Deed’s Mill, trading as Eagle’s Leather, helped to produce the scabbard for the Stalingrad Sword. This was presented in 1943 to honour the City that withstood a lengthy siege by Hitler’s army during World War II. Mitcham’s herb gardens, mint, chamomile and lavender fields, gave rise to the processing and production of medical products, essential oils, soap and perfume. With steam and electricity, other industries developed away from the river. By 1900, Mitcham was London’s centre for the paint and varnish industry. Gun powder production led to the opening of Pains’ Firework Factory and Pascall’s produced chocolate and confectionery. Elsewhere in Merton, Lines brothers Tri-ang Toy Factory, was the biggest toy manufacturer in the world. The Tandem works, later Fry metals, also had a local foundry and produced bronzes, solders and white metals. In the tradition of earlier medical products from herbs and plants, Everett’s, supplied the country with hypodermic and blood testing needles, GH Zeal remains the biggest supplier of thermometers to the UK and Northern Ireland, whilst BOC supplies medical and industrial gases to the UK and worldwide. Decca records had a production works near West Barnes and Raynes Park – this housed its only UK centre for the pressing of ( vinyl ) records.
