James Watt was a Scottish inventor and mechanical engineer, best known for his improvements to the steam engine. Born in 1736, he played a crucial role in the Industrial Revolution by making steam engines more efficient and practical for various industries. His innovations, such as the separate condenser, allowed engines to use less fuel and produce more power, which helped to revolutionize transportation and manufacturing. Watt's contributions extended beyond just the steam engine; he also developed the concept of horsepower, which is still used today to measure engine power. In recognition of his work, the unit of power, the watt, is named after him. His legacy continues to influence engineering and technology, making him a key figure in history.
