John Grundy (1807–1893) was a grocer with a shop in Elliott Street, Tyldesley, near Manchester. At Tyldesley Top ChapelThe township of Tyldesley's first place of worship, built in 1789. where he was a churchwarden, Grundy experimented heating it using a stove, flues, chimney and ventilators and succeeded in warming it.[1] He decided to manufacture heating apparatus and set up John Grundy Ltd in Lower Elliott Street in 1857. He was granted patent BP 2949 for the apparatus in 1864, and other patents were granted for improvements made in the following years. A monument dedicated to him is sited near the gates of Top Chapel.[2]

Grundy’s son, also named John Grundy (1844–1913), was working in the family shop in 1861. After Grundy senior founded the heating company, father and son continued working in the shop, the census of 1871 lists them as flour dealers. By this time the company was successful, and changing the family fortunes.[2]

Grundy junior was living in Hackney, London by 1881, and later in the 1880s moved to a more fashionable area in City Road, Islington, which became the company’s head office.

The company produced iron castings for a wide range of purposes, including machine-tool beds for Churchill Machine Tool Co.[3]
