Lodge Plugs

The company had its origins in the work of Sir Oliver Lodge (1851-1940), who was a pioneer in the field of electromagnetism.

Two of his sons Francis (Brodie) and Alexander Lodge, decided to turn their father's discoveries onto a commercial venture.

Following the merger, production initially took place in part of the Hunter's Lamp factory in Lower Hillmorton Road, Rugby and later on in Albert Street, before a dedicated factory was opened on St Peter's Road, Rugby, in 1916, whilst the main offices remained in Birmingham.

In 1919, the name was shortened to Lodge Plugs Ltd[1][2] The company set up a second factory in Olney, Buckinghamshire in 1940 in order to cater for the increased demand due to World War II.

Production was then moved to Italy, and the plugs were marketed under the name "Golden Lodge"[1] The Rugby factory on St Peter's Road, continued to supply Sintox products, marketed under the name of Lodge Ceramics Ltd, until 1992, when it was sold to Morgan Matroc.
