8+ History: When Were Hydraulics Invented & Used?

The utilization of liquids to transmit force and power has ancient roots, dating back to civilizations that observed and harnessed the properties of water. Examples include early irrigation systems and water wheels, demonstrating a practical understanding of fluid dynamics. However, a systematic and controlled application of fluid power, as understood in modern engineering, represents a later development.

The formalization of this technology is often attributed to the 17th and 18th centuries. Blaise Pascal’s principles concerning pressure in fluids laid the groundwork for understanding how force can be multiplied through a contained liquid. Joseph Bramah is credited with patenting the hydraulic press in 1795. This invention signified a significant step forward, showcasing the ability to generate considerable force through a small input, marking a turning point in the development of fluid power technology.
