Mechanical engineer in the context of "Industrial machinery"

Gaspard-Gustave de Coriolis (French: [ɡaspaʁ ɡystav də kɔʁjɔlis]; 21 May 1792 – 19 September 1843) was a French mathematician, mechanical engineer and scientist. He is best known for his work on the supplementary forces that are detected in a rotating frame of reference, leading to the Coriolis effect. He was the first to apply the term travail (translated as "work") for the transfer of energy by a force acting through a distance, and he prefixed the factor +1⁄2 to Leibniz's concept of vis viva, thus specifying today's kinetic energy.

The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m⋅s. It is used to quantify the rate of energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776, which became fundamental for the Industrial Revolution.

Frederick Winslow Taylor (March 20, 1856 – March 21, 1915) was an American mechanical engineer. He was widely known for his methods to improve industrial efficiency. He was one of the first management consultants. In 1909, Taylor summed up his efficiency techniques in his book The Principles of Scientific Management which, in 2001, Fellows of the Academy of Management voted the most influential management book of the twentieth century. His pioneering work in applying engineering principles to the work done on the factory floor was instrumental in the creation and development of the branch of engineering that is now known as industrial engineering. Taylor made his name, and was most proud of his work, in scientific management; as a result, scientific management is sometimes referred to as Taylorism. However, he made his fortune patenting steel-process improvements.

Jacob Perkins (July 9, 1766 – July 30, 1849) was an American inventor, mechanical engineer and physicist based in the United Kingdom. Born in Newburyport, Massachusetts, Perkins was apprenticed to a goldsmith. He soon made himself known with a variety of useful mechanical inventions and eventually had twenty-one American and nineteen English patents. Sometimes known as the father of the refrigerator. He was elected a Fellow of the American Academy of Arts and Sciences in 1813 and a member of the American Philosophical Society in 1819.

Franz Reuleaux (French: [ʁœlo]; German: [ʁøˈloː]; 30 September 1829 – 20 August 1905) was a German mechanical engineer and a lecturer at Technische Hochschule Berlin (today Technische Universität Berlin), later appointed as the president of the academy. He was often called the father of kinematics. He was a leader in his profession, contributing to many important domains of science and knowledge.

Today, he may be best remembered for the Reuleaux triangle, a curve of constant width that he helped develop as a useful mechanical form.
