John Penn and Sons was an English engineering company based in London, and mainly known for its marine steam engines.
History
Establishment
In 1799, engineer and millwright John Penn (born in Taunton, Somerset, 1770; died 6 June 1843)[1] started an agricultural engineering business on the site at the junction of Blackheath and Lewisham Roads (close to modern-day Deptford Bridge) in south-east London. It grew in two decades to be one of the major engineering works in the London area.[2] The focus of the firm remained in agriculture until the 1830s and 1840s, when Penn's son, also John Penn, took over the company and it began to specialise in building marine steam engines.
