Hammersmith originally meant "(Place with) a hammer smithy or forge", first recorded in 1294.
Hammersmith is in the historic county of Middlesex. It was the name of a parish, and of a suburban district, within the hundred of Osselstone. In the early 1660s, Hammersmith's first parish church, which later became St Paul's, was built by Sir Nicholas Crispe who ran the brickworks in Hammersmith. It contained a monument to Crispe as well as a bronze bust of King Charles I by Hubert Le Sueur. In 1696 Sir Samuel Morland was buried there. The church was completely rebuilt in 1883, but the monument and bust were transferred to the new church.
Hammersmith Bridge was first designed by William Tierney Clark, opening in 1827 as the first suspension bridge crossing the River Thames. Overloading in this original structure led to a redesign by Joseph Bazalgette, which was built over the original foundations, and reopened in 1887. In 1984–1985 the bridge received structural support, and between 1997 and 2000 the bridge underwent major strengthening work.
In 1745, two Scots, James Lee and Lewis Kennedy, established the Vineyard Nursery, over six acres devoted to landscaping plants. During the next hundred and fifty years the nursery introduced many new plants to England, including fuchsia and the standard rose tree.
Major industrial sites included the Osram lamp factory at Brook Green, the J. Lyons factory (which at one time employed 30,000 people). During both World Wars, Waring & Gillow's furniture factory, in Cambridge Grove, became the site of aircraft manufacture.
