Biography

James Watt: life and legacy

Life and career

Watt's separate condenser reduced the fuel consumption of Newcomen engines. Partnership with Matthew Boulton turned invention into a commercial system of manufacture, patents and service. Steam power expanded across mining, manufacturing and transport, though Watt did not invent the steam engine itself.

Historical context

Industrial innovation joined invention to capital, labour, patents, raw materials and global markets. Engineering achievement should be read alongside workplace danger and environmental change.

Legacy and interpretation

James Watt's reputation has been shaped by commemoration, political argument and the survival of unequal evidence. A responsible biography compares contemporary records with later interpretation, recognises people affected by their decisions and avoids reducing broad change to one famous life.
