'''John Smeaton''' {{Post-nominals|FRS|country=GBR|size=100%}} (8 June 1724&nbsp;– 28 October 1792) was an English [[civil engineer]] responsible for the design of bridges, [[canal]]s, [[harbour]]s and [[lighthouse]]s.<ref>{{cite web|last1=Knowles|first1=Eleanor|title=Engineer Biography: John Smeaton|url=http://www.engineering-timelines.com/who/Smeaton_J/smeatonJohn.asp|website=Engineering Timelines|access-date=31 January 2017}}</ref> He was also a capable mechanical engineer and an eminent [[physicist]].

==Law and physics==
Smeaton was born in [[Austhorpe]], [[Leeds]], England. After studying at [[Leeds Grammar School]] he joined his father's law firm, but left to become a mathematical instrument maker (working with [[Henry Hindley]]), developing, among other instruments, a [[pyrometer]] to study material expansion.  In 1750, his premises were in the [[Great Turnstile]] in Holborn.<ref>{{citation |title=Great Men of Great Britain |editor-first=Elihu |editor-last=Rich |publisher=D.

He was elected a [[Fellow of the Royal Society]] in 1753 and in 1759 won the [[Copley Medal]] for his research into the mechanics of [[waterwheel]]s and [[windmill]]s.<ref>{{cite web|last1=Knowles|first1=Eleanor|title=Engineer Biography: John Smeaton, water wheels and mill works|url=http://www.engineering-timelines.com/who/Smeaton_J/smeatonJohn6.asp|website=Engineering Timelines|access-date=31 January 2017}}</ref> His 1759 paper "An Experimental Enquiry Concerning the Natural Powers of Water and Wind to Turn Mills and Other Machines Depending on Circular Motion"<ref name="Phil.

Over the period 1759–1782 he performed a series of further experiments and measurements on water wheels that led him to support and champion the ''[[vis viva]]'' theory of German [[Gottfried Leibniz]], an early formulation of [[conservation of energy]]. This led him into conflict with members of the academic establishment who rejected Leibniz's theory, believing it inconsistent with Sir [[Isaac Newton]]'s [[conservation of momentum]].{{citation needed|date=February 2023}}

==Smeaton coefficient==
In his 1759 paper "An Experimental Enquiry Concerning the Natural Powers of Water and Wind to Turn Mills and Other Machines Depending on Circular Motion" Smeaton developed the concepts and data which became the basis for the ''Smeaton coefficient'',<ref name=cof>{{cite web|url=https://www.centennialofflight.net/essay/Dictionary/Smeaton/DI75.htm|title=Smeaton's Coefficient|website=www.centennialofflight.net}}</ref> the lift equation used by the [[Wright brothers]]. It has the form:<ref>{{cite web |url=http://wright.nasa.gov/airplane/liftold.html |title=Lift equation of the early 1900s |publisher=Wright.nasa.gov |date=25 March 2010 |access-date=31 May 2010 |archive-date=27 May 2010 |archive-url=https://web.archive.org/web/20100527205655/http://wright.nasa.gov/airplane/liftold.html |url-status=dead }}</ref>

:<math>L = k V^2 A C_l \,</math>

where:
:<math>L</math> is the lift
:<math>k</math> is the Smeaton coefficient (see note below)
:<math>V</math> is the velocity
:<math>A</math> is the area in square feet
:<math>C_l</math> is the [[lift coefficient]] (the lift relative to the drag of a plate of the same area)

The Wright brothers determined with [[wind tunnel]]s that the Smeaton coefficient value of 0.005<ref name=cof/> was incorrect and should have been 0.0033.<ref name=Dodson>{{cite journal |last=Dodson |first=M.&nbsp;G. |title=An Historical and Applied Aerodynamic Study of the Wright Brothers' Wind Tunnel Test Program and Application to Successful Manned Flight |journal=US Naval Academy Technical Report |volume=USNA-334 |year=2005 |url=http://archive.rubicon-foundation.org/3585 |archive-url=https://web.archive.org/web/20090514071842/http://archive.rubicon-foundation.org/3585 |url-status=usurped |archive-date=14 May 2009 |access-date=17 March 2009}}</ref> In modern analysis, the lift coefficient is normalised by the [[dynamic pressure]] instead of the Smeaton coefficient.

==Civil engineering==
[[File:Smeaton's Lighthouse00.jpg|thumb|right|{{center|[[Smeaton's Lighthouse]]}}]]
Smeaton is important in the history, rediscovery of, and development of modern [[cement]], identifying the compositional requirements needed to obtain "hydraulicity" in lime; work which led ultimately to the invention of [[Portland cement]]. Portland cement led to the re-emergence of concrete as a modern building material, largely due to Smeaton's influence.

Recommended by the Royal Society, Smeaton designed the third [[Eddystone Lighthouse]] (1755–59).<ref>{{cite web|title=Eddystone Lighthouse, Smeaton Tower substructure|url=http://www.engineering-timelines.com/scripts/engineeringItem.asp?id=924|website=Engineering Timelines|access-date=31 January 2017}}</ref> He pioneered the use of '[[hydraulic lime]]' (a form of [[mortar (masonry)|mortar]] that will set under water) and developed a technique involving [[Dovetail joint|dovetailed]] blocks of granite in the building of the lighthouse. 
[[File:Granite bust by Philip Chatfield in Smeaton's Tower Plymouth.jpg|thumb|left|Granite bust by Philip Chatfield in Smeaton's Tower Plymouth]]
His lighthouse remained in use until 1877 when the rock underlying the structure's foundations had begun to erode; it was dismantled and partially rebuilt at [[Plymouth Hoe]] where it is known as [[Smeaton's Tower]].<ref>{{cite web|title=Eddystone Lighthouse, Smeaton Tower (relocated)|url=http://www.engineering-timelines.com/scripts/engineeringItem.asp?id=67|website=Engineering Timelines|access-date=31 January 2017}}</ref> In 2020 a Cornish granite bust of Smeaton by Philip Chatfield, commissioned by [[The Box, Plymouth]] and funded by [[Trinity House]], was installed in the tower's lantern chamber before its reopening.

Smeaton is considered to be the first [[expert witness]] to appear in an English court. Because of his expertise in engineering, he was called to testify in court for a case related to the silting-up of the harbour at [[Wells-next-the-Sea]] in Norfolk in 1782.<ref>{{cite web|url=https://www.ryemuseum.co.uk/smeatons-harbour/|title=Smeaton's Harbour - Rye Castle Museum|website=www.ryemuseum.co.uk|access-date=8 September 2018|archive-url=https://web.archive.org/web/20180702204709/https://www.ryemuseum.co.uk/smeatons-harbour/|archive-date=2 July 2018|url-status=dead}}</ref> He also acted as a consultant on the disastrous 63-year-long New Harbour at [[Rye, East Sussex|Rye]], designed to combat the silting of the port of [[Winchelsea]]. The project is now known informally as "Smeaton's Harbour", but despite the name his involvement was limited and occurred more than 30 years after work on the harbour commenced.<ref name="ryemuseum">[http://www.ryemuseum.co.uk/index.php/2009/02/smeatons-harbour/ Rye Museum website] {{webarchive|url=https://web.archive.org/web/20110726111459/http://www.ryemuseum.co.uk/index.php/2009/02/smeatons-harbour/ |date=26 July 2011 }}</ref> It closed in 1839.<ref>{{cite web|url=https://ryesown.co.uk/smeatons-harbour/|title=Smeaton's Harbour – Rye's Own Magazine|website=ryesown.co.uk|access-date=8 September 2018}}</ref>

==Mechanical engineer==
Employing his skills as a mechanical engineer, he devised a [[water engine]] for the [[Royal Botanic Gardens, Kew|Royal Botanic Gardens]] at [[Kew]] in 1761 and a watermill at [[Alston, Cumbria|Alston]], Cumbria in 1767 (he is credited by some with inventing the cast-iron axle shaft for [[water wheel]]s). In 1782 he built the Chimney Mill at [[Spital Tongues]] in [[Newcastle upon Tyne]], the first 5-sailed [[smock mill]] in Britain. He also improved [[Thomas Newcomen]]'s [[Newcomen engine|atmospheric engine]], erecting one at Chacewater mine, [[Wheal Busy]], in Cornwall in 1775 which was both highly efficient and the most powerful at the time.<ref name = "ODNBSmeaton">{{Cite ODNB|doi=10.1093/ref:odnb/25746|title=Smeaton, John|last=Skempton|first=A.

In 1789 Smeaton applied an idea by [[Denis Papin]], by using a force pump to maintain the pressure and fresh air inside a [[diving bell]].<ref name=davis1955>{{cite book |last=Davis |first=R.&nbsp;H. |title=Deep Diving and Submarine Operations |year=1955 |edition=6th |publisher=[[Siebe Gorman|Siebe Gorman & Company Ltd]] |location=Tolworth, Surbiton, Surrey |page=693 |author-link=Robert Davis (inventor) }}</ref><ref name=dive_hx>{{cite journal |last=Acott |first=C. |title=A brief history of diving and decompression illness. |journal=South Pacific Underwater Medicine Society Journal |volume=29 |issue=2 |year=1999 |issn=0813-1988 |oclc=16986801 |url=http://archive.rubicon-foundation.org/6004 |archive-url=https://web.archive.org/web/20080627230124/http://archive.rubicon-foundation.org/6004 |url-status=usurped |archive-date=27 June 2008 |access-date=17 March 2009 }}</ref> This bell, built for the [[Hexham Bridge]] project, was not intended for underwater work, but in 1790 the design was updated to enable it to be used underwater on the breakwater at Ramsgate Harbour.<ref name=dive_hx/> Smeaton is also credited with explaining the fundamental differences and benefits of overshot versus undershot water wheels. Smeaton experimented with the [[Thomas Newcomen|Newcomen]] steam engine and made marked improvements around the time [[James Watt]] was building his first engines ({{circa|late 1770s}}).<ref>[http://www.engineering-timelines.com/who/Smeaton_J/smeatonJohn10.asp John Smeaton- Engineering Timeline] {{webarchive|url=https://web.archive.org/web/20120307232238/http://www.engineering-timelines.com/who/Smeaton_J/smeatonJohn10.asp |date= 7 March 2012 }}</ref>

Smeaton died after suffering a stroke while walking in the garden of his family home at Austhorpe, and was buried in the [[St Mary's Church, Whitkirk|parish church at Whitkirk]], West Yorkshire. His surviving daughters erected a memorial to him and his wife which is on the [[chancel]] wall of the church.<ref>{{cite web |title=Smeaton Memorial |url=https://memorials.whitkirkchurch.org.uk/memorials/nmkx |access-date=2 July 2020 |archive-date=30 October 2020 |archive-url=https://web.archive.org/web/20201030044916/https://memorials.whitkirkchurch.org.uk/memorials/nmkx |url-status=dead }}</ref><ref name=Whitkirk>{{cite web |title=John Smeaton - St Mary's Church |url=https://whitkirkchurch.org.uk/history/john-smeaton/ |access-date=2 July 2020}}</ref>

Due to the decay of the rock beneath the Eddystone Lighthouse the structure needed to be replaced. When the upper section of Smeaton's lighthouse (which included the lantern, store and living and watch room) was about to be removed, it was suggested that some of it be brought to Whitkirk and set up as a memorial to him. Unfortunately, the project was deemed too expensive as it was estimated that it would cost around £1800.<ref>{{Cite book |last=Kirk |first=George E. |title=A History of the Parish Church of St Mary, Whitkirk, Leeds |publisher=John Whitehead & Son |year=1935 |pages=126}}</ref>

He is highly regarded by other engineers, having contributed to the [[Lunar Society]] and founded the [[Smeatonian Society of Civil Engineers|Society of Civil Engineers]] in 1771. He coined the term ''[[civil engineers]]'' to distinguish them from military engineers graduating from the [[Royal Military Academy at Woolwich]].<ref name="Denny"/> The Society was a forerunner of the [[Institution of Civil Engineers]], established in 1818, and was renamed the Smeatonian Society of Civil Engineers in 1830. His pupils included canal engineer [[William Jessop]] and architect and engineer [[Benjamin Latrobe]].

The pioneering [[constant of proportionality]] describing pressure varying inversely as the square of the velocity when applied to objects moving in air was named ''Smeaton's coefficient'' in his honour.<ref name=cof/> Based on his concepts and data, it was used by the [[Wright brothers]] in their pursuit of the first successful [[heavier-than-air aircraft]].

Between 1860 and 1894 the design of the reverse side of the [[History of the British penny (1714–1901)|old penny coin]] showed (behind [[Britannia]]) a depiction of Smeaton’s Eddystone lighthouse.<ref name=Whitkirk/>

Smeaton is one of six civil engineers depicted in the [[Robert Stephenson|Stephenson]] stained glass window, designed by [[William Wailes]] and unveiled in [[Westminster Abbey]] in 1862.<ref>{{cite web|title=Westminster Abbey – Robert Stephenson|url=http://www.westminster-abbey.org/our-history/people/robert-stephenson|access-date=26 June 2015}}</ref> A memorial stone commemorating Smeaton himself was unveiled in the Abbey on 7 November 1994, by Noel Ordman, President of the [[Smeatonian Society of Civil Engineers]].<ref>{{cite web|title=Westminster Abbey – John Smeaton|url=http://www.westminster-abbey.org/our-history/people/john-smeaton|access-date=26 June 2015}}</ref><ref>{{cite news|title=Civil Honour|newspaper=The Times|date=7 November 1994|page=16|issn=0140-0460}}</ref> 
[[File:Johm Smeaton Viaduct 2013.JPG|thumb|right|Signs on the John Smeaton [[Viaduct]]]]
[[John Smeaton Academy]], a secondary school in the suburbs of Leeds adjacent to the [[Pendas Fields]] estate near Austhorpe, is named after Smeaton. He is also commemorated at the [[University of Plymouth]], where the Mathematics and Technology Department is housed in a building named after him. A viaduct in the final stage of the [[Leeds Inner Ring Road]], opened in 2008, was named after him.

Smeaton is mentioned in the song "[[I Predict a Riot]]" (as a symbol of a more dignified and peaceful epoch in Leeds history; and in reference to a Junior School House at Leeds Grammar School, which lead singer Ricky Wilson attended) by the indie rock band [[Kaiser Chiefs]], who are natives of Leeds.
