Engine, Steam Power and Railway Engineers

the Pyréolophore, one of the world's first internal combustion engines

Thomas Newcomen (; February 1664-5 August 1729) was an English inventor, creator of the atmospheric engine in 1712, Baptist preacher by calling and ironmonger by trade.

James Watt (; 30 January 1736 (19 January 1736 OS), 25 August 1819) was a Scottish inventor, engineer and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1776, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world.

Carl (or Karl) Friedrich Benz (German: [kaʁl ˈfʁiːdʁɪç ˈbɛnts] ; born Karl Friedrich Michael Vaillant; 25 November 1844-4 April 1929) was a German engine designer and automotive engineer.

He was a pioneer of internal-combustion engines and automobile development.

He was the first to patent the four-stroke engine in 1862, but he did not build one and the idea was subsequently developed by Nicolaus Otto and other engineers.

He invented the first commercially used steam-powered device, a steam pump which is often referred to as the "Savery engine".

Rudolf Christian Karl Diesel (English: , German: [ˈʁuːdɔlf ˈkʀɪsti̯an kaʁl ˈdiːzl̩] ; 18 March 1858-29 September 1913) was a German inventor and mechanical engineer.

Renowned as the "Father of Railways", Stephenson was considered by the Victorians as a great example of diligent application and thirst for improvement.

He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were the development of the first high-pressure steam engine and the first working railway steam locomotive.

George Baldwin Selden (September 14, 1846, January 17, 1922) was an American patent lawyer and inventor from New York who was granted a U.S. patent for an automobile in 1895.

Émile Constant Levassor (21 January 1843-14 April 1897) was a French engineer and a pioneer of the automobile industry and car racing in France.

Denis Papin FRS (French pronunciation: [dəni papɛ̃]; 22 August 1647-26 August 1713) was a French Huguenot physicist, mathematician and inventor, best known for his pioneering invention of the steam digester, the forerunner of the pressure cooker, the steam engine, the centrifugal pump, and a submersible boat.

Frederick William Lanchester (23 October 1868-8 March 1946), was an English polymath and engineer who made important contributions to automotive engineering and to aerodynamics, and co-invented the topic of operations research.

Sir Frederick Henry Royce, 1st Baronet (; 27 March 1863-22 April 1933) was an English engineer famous for his designs of car and aeroplane engines that had a reputation for reliability and longevity.

In 1948, he established Honda Motor Co., Ltd. and oversaw its expansion from a wooden shack manufacturing bicycle motors to a multinational automobile and motorcycle manufacturer.

Wilhelm Maybach (German: [ˈvɪlhɛlm ˈmaɪbax] ; 9 February 1846-29 December 1929) was an early German engine designer and industrialist.

Nicolaus August Otto (German pronunciation: [ˈnɪkolaʊ̯s ˈaʊ̯ɡʊst ˈɔto]; 10 June 1832-26 January 1891) was a German engineer who successfully developed the compressed charge internal combustion engine which ran on petroleum gas and led to the modern internal combustion engine.

successfully developed the compressed charge internal combustion engine which ran on petroleum gas and led to the modern internal combustion engine

best known for his invention of the multi-stage (compounded) steam turbine

Perkins made an experimental high pressure steam engine working at pressures up to 2,000 psi

He received thirty patents over a sixteen-year career, fourteen of which were on pneumatic street railway innovations.
