Savery was a military engineer who attained the rank of trench master by 1696, and acquired the title of ‘Captain’. His inventiveness was perhaps stimulated by his knowledge of tin‐ and copper‐mining in his native Devon. Savery's outstanding achievement was the invention of a machine for raising water by steam pressure, for which he took out a patent (No. 356) in 1698, calling it ‘the miner's friend’. His patent was adapted by Thomas Newcomen in his much more successful atmospheric engine of 1712.
