James Watt (1736-1819), engineer who developed the steam engine for commercial applications
James Watt trained as a scientific instrument maker and developed into an outstanding engineer, scientist and inventor. Watt's practical and enquiring mind led him to repair a malfunctioning teaching model at Glasgow University of a Newcomen steam engine, culminating in his invention in 1765 of the separate condenser to dramatically improve its efficiency. With subsequent improvements in engine design, Watt's engine developed into a form in which it could be applied effectively to power machinery in mines, mills and factories, ending dependence on water power for driving the industrial revolution.
Watt's interest and expertise extended far beyond mechanical engineering and the steam engine however. While working in Glasgow he developed a great and enduring interest in chemistry which he applied at the Delftfield pottery. He also practised as a civil engineer, planning a number of canals, roads, railways and docks. He was interested in the development of manufacturing practices in factories, invented a machine for copying letters and drawings, and, in his retirement, a machine for copying sculptures.

Watt's steam engine provided a huge impetus to the industrial revolution which occurred in the later eighteenth and early nineteenth centuries, as recognised by his business partner Matthew Boulton who stated in 1776: 'I sell here, Sir, what all the world desires to have - Power'. Watt has been cited as one of the most influential people in human history, and as "the most useful man who ever lived".
In the course of developing his steam engine Watt developed a profound understanding of what today is called thermodynamics, and in 1796 developed the indicator to aid understanding of the behaviour of the steam inside the engine's cylinder. Aware of the need to help potential purchasers of his new engine comprehend its output, Watt adopted the term 'horsepower', a key step in the standardisation of the measurement of power. Watt's name and significance is recognised by the International System of Units (SI) which titles its unit of power the 'watt'.
