  • Peter Ewart (14 de maig de 1767 – 15 de setembre de 1842) va ser un enginyer britànic que influí sobre les teories sobre la turbina i de la termodinàmica. Era el fill d'un ministre de l'Església d'Escòcia de Troqueer prop de Dumfries. El seu germà Joseph Ewart va ser ambaixador a Prússia i un altre germà, William, va ser el pare de William Ewart, un polític contrari a la pena de mort i soci de Sir John Gladstone, el qual va ser el pare del primer ministre William Ewart Gladstone.Es graduà a la Universitat d'Edinburgh, treballà en rodes hidràuliques amb Matthew Boulton i James Watt de qui cap a 1790 va ser l'agent a Manchester. El 1792, deixà de treballar amb Boulton i Watt per a ser un soci de Samuel Oldknow en la indústria del cotó. Però un any després Peter tornà a l'enginyeria. El 1798 s'associà amb Samuel Greg, i va instal·lar una innovadora roda hidràulica al riu Bollin a Cheshire. Cap a 1811, Ewart deixà la seva societat amb Greg i es va dedicar als seus propis negocis i al treball científic. Junt amb John Dalton, va tenir la vicepresidència de la Manchester Literary and Philosophical Society i va tenir un paper actiu en la controvèrsia sobre la calor, el treball mecànic i l'energia. El 1813, encoratjat per Dalton i motivat per un escrit de John Playfair, publicà On the measure of moving force on defensava la idea naixent de la conservació de l'energia capitanejada per John Smeaton. Aquest escrit influí molt en l'alumne de Dalton James Prescott Joule. Va ser un dels fundadors del Manchester Mechanics' Institute.Va morir en un accident el 1842 a Woolwich Dockyard quan una cadena es va desprendre d'una maquinària de vaport.

  • Peter Ewart (14 May 1767 – 15 September 1842) was a British engineer who was influential in developing the technologies of turbines and theories of thermodynamics.He was son of the Church of Scotland minister of Troqueer near Dumfries, and was one of eleven children. His brother Joseph Ewart became British ambassador to Prussia; John, a doctor, became Chief Inspector of East India Company hospitals in India; and William, father of William Ewart. was business partner of Sir John Gladstone, father of William Ewart Gladstone, whose godfather he was and whom he was named after.After graduating from the University of Edinburgh,[citation needed] he was apprenticed to millwright John Rennie. His work with water wheels[citation needed] led him to work with Matthew Boulton and James Watt for whom by 1790 he was agent in Manchester. At the same time as acting as agent he was also trading on his own account as a millwright, enabling him to provide the complementary shafts, gears and other necessities to harness the power of the Boulton & Watt steam engines.In 1792, frustrated in administering the immature and, as yet, unreliable machinery,[citation needed] he left Boulton and Watt to work in partnership with Samuel Oldknow in a cotton bleaching and calico printing venture. He anticipated this being a profitable concern but the partnership was dissolved within a year and he returned to engineering. In 1798 he went into partnership with Samuel Greg, installing an innovative water wheel at Greg's Quarry Bank Mill on the River Bollin in Cheshire. As a standby, he installed a Watt steam engine[citation needed].By 1811, Ewart had abandoned the venture with Greg to concentrate on his own manufacturing business but also his scientific work. He became, along with John Dalton, a vice-president of the Manchester Literary and Philosophical Society and became active in the contemporary controversies about heat, work and energy. Motivated by a paper of John Playfair and encouraged by Dalton, in 1813 he published On the measure of moving force in which he defended the nascent ideas of the conservation of energy championed by John Smeaton. The paper was strongly to influence Dalton's pupil James Prescott Joule. A vocal advocate of the application of scientific knowledge in engineering, he was one of the founders of the Manchester Mechanics' Institute.Ewart took up the post of Chief Engineer and Chief Inspector of Machinery with the Admiralty in 1835 and died on 15 September 1842 at Woolwich Dockyard when a chain snapped as he was supervising the removal of a boiler.
