History of Hydraulics - Joseph Bramah. Joseph Bramah (13 April 1748 â 9 December 1814), Wentworth, Yorkshire, England, was an inventor and locksmith. He is best known for having invented the hydraulic press. Along with William George Armstrong, he can be considered one of the two fathers of hydraulic engineering.
While the Spaniard first patented a steam-operated machine for use in mining, an Englishman is usually credited with inventing the first steam engine. In 1698, Thomas Savery, an engineer and inventor, patented a machine that could effectively draw water from flooded mines using steam pressure. Savery used principles set forth by Denis Papin, a French-born British physicist who invented the pressure cooker. Papin's ideas surrounding a cylinder and piston steam engine had not previously been used to build a working engine, but by 1705, Savery had turned Papin's ideas into a useful invention.
