A Thomas Annan photograph of a portrait of James Watt (1736-1819). The painting was by John Partridge.
Watt was born in Greenock and became a mechanical instrument maker in Glasgow, working at the University and in business on his own account. He also worked as a civil engineer. In 1763 he repaired a Newcomen steam engine and thought of various means by which he believed he could improve its safety and efficiency. He devised a steam engine with a separate condenser for used steam, and in the 1770s began manufacturing his steam engines in partnership with a businessman, Matthew Boulton, in Birmingham. He subsequently developed the rotary-motion steam engine that proved highly effective in the textile industry.
