Sir Charles Algernon Parsons (1854–1931), a British mechanical engineer who invented the steam turbine, which greatly increased the efficiency of converting steam into power by allowing the steam to expand gradually in 15 stages. A rotor turned blades placed in a cylinder such that the space between blades enclosed a pressurized space where the steam could expand; each successive blade-bound space had lower pressure, eliciting increasing degrees of expansion. His turbine-driven engines for ships greatly increased the speed of seafaring transportation. In 1897, Parsons designed the Turbinia, the first sea vessel propelled by turbines. The ship’s amazing speed, demonstrated at Queen Victoria’s Diamond Jubilee Fleet Review at Spithead, England on June 26, 1897, immediately generated a huge fanfare and led to the construction of many turbine-propelled warships for the British navy.
