'''Sir Hiram Stevens Maxim''' (5 February 1840 – 24 November 1916) was an {{wipe|United States}}-born {{wipe|United Kingdom}} [[Social:Inventor|inventor]] best known as the creator of the first [[Engineering:Automatic firearm|automatic]] [[Engineering:Machine gun|machine gun]], the Maxim gun.<ref>{{cite book|title=Great Inventors and Inventions|publisher=Courier Dover Publications|url=https://books.google.com/books?id=V1h_0wb_AM4C&q=Hiram+Maxim+and+inventor+of+Maxim+gun&pg=PA24|isbn=9780486297842|date=10 July 1997}}</ref> Maxim held patents on numerous mechanical devices such as [[Engineering:Hair iron|hair-curling irons]], a [[Engineering:Mousetrap|mousetrap]], and steam pumps.

Maxim experimented with powered flight;  his large aircraft designs were never successful. He designed a highly successful amusement ride called the "Captive Flying Machine" to fund his research while generating public interest in [[Physics:Flight|flight]].<ref>{{cite book|url=https://books.google.com/books?id=7ccymjJZxLcC&q=Hiram+Maxim+and+powered+flight&pg=PA31|title=The American aviation experience: a history |publisher=SIU Press|isbn=9780809323715|year=2000|last1 = Brady|first1 = Tim}}</ref><ref>{{cite book|url=https://archive.org/details/playfulcrowdplea0000cros|url-access=registration|page=[https://archive.org/details/playfulcrowdplea0000cros/page/45 45]|quote=Captive Flying Machine.|title=The playful crowd: pleasure places in the twentieth century|publisher=Columbia University Press|isbn=9780231127240|year=2005}}</ref>

Maxim moved from the United States to the United Kingdom at the age of 41, and remained an American citizen until he became a [[Philosophy:Naturalization|naturalised]] British citizen in 1899, and received a knighthood in 1901.<ref>{{cite book|title=Sir Hiram Maxim|publisher=Encyclopædia Britannica|url=http://www.britannica.com/EBchecked/topic/370419/Sir-Hiram-Maxim}}</ref><ref>{{cite book|title=Who's who in World War One|publisher=Psychology Press|url=https://books.google.com/books?id=06TdWzZyH3sC&q=Hiram+Stevens+Maxim+nationality&pg=PA201|isbn=9780203438817|date=1 June 2002}}</ref>

==Birth and early life==
Maxim was born in Sangerville, Maine on 5 February 1840. He became an apprentice coachbuilder at the age of 14 and ten years later, took up a job at the machine works of his uncle, Levi Stephens, at Fitchburg, Massachusetts. He subsequently worked as an instrument-maker and as a draughtsman.<ref>{{cite web|url=http://www.gracesguide.co.uk/Hiram_Stevens_Maxim|title=Hiram Stevens Maxim |publisher= Grace's Guide|access-date= 6 December 2013}}</ref>
(His early jobs in these areas led him to be often disappointed with workers when he ran his own companies later on in life.){{Citation needed|date=February 2019}} Hiram called himself a Protestant.<ref>{{cite book | url=https://books.google.com/books?id=CH48DwAAQBAJ&dq=%22hiram+maxim%22+%22protestant%22&pg=PA220 | isbn=978-0-19-518951-3 | title=Inventing Modern: Growing up with X-Rays, Skyscrapers, and Tailfins | date=18 May 2005 | publisher=Oxford University Press }}</ref>

==Inventions==
Maxim, a longtime sufferer of [[Medicine:Bronchitis|bronchitis]], patented and manufactured a pocket [[Chemistry:Menthol|menthol]] [[Engineering:Inhaler|inhaler]] and a larger "Pipe of Peace", a steam inhaler using [[Biology:Pine|pine]] vapour, that he claimed could relieve [[Medicine:Asthma|asthma]], [[Medicine:Tinnitus|tinnitus]], hay fever and [[Medicine:Catarrh|catarrh]].<ref>"Sir Hiram Maxim's great Invention", ''The Times'', 19 July 1910.</ref> After being criticised for applying his talents to [[Philosophy:Quackery|quackery]], he protested that "it will be seen that it is a very creditable thing to invent a killing machine, and nothing less than a disgrace to invent an apparatus to prevent human suffering".<ref name="nyt" />[[File:Sir Hiram Stevens Maxim00.jpg|right|thumb|Maxim caricatured by Spy for Vanity Fair, 1904]]He also invented a curling iron, an apparatus for demagnetising watches, magno-electric machines, devices to prevent the rolling of ships, eyelet and riveting machines, aircraft artillery, an aerial torpedo gun, coffee substitutes, and various oil, steam, and gas engines.<ref>{{Cite web |url=http://www.sangerville.lib.me.us/hiram.html |title=Hiram's inventions |access-date=12 November 2003 |archive-date=28 December 2011 |archive-url=https://web.archive.org/web/20111228062322/http://www.sangerville.lib.me.us/hiram.html |url-status=dead }}</ref>

A large furniture factory had repeatedly burned down, and Maxim was consulted on how to prevent a recurrence. As a result, Maxim invented the first automatic [[Engineering:Fire sprinkler|fire sprinkler]]. It would douse the areas that were on fire, and it would report the fire to the fire station. Maxim was unable to sell the idea elsewhere, but when the patent expired the idea was used.<ref>{{Citation |last=Chinn |first=George M. |title=The Machine Gun |year=1951 |volume=I |publisher=Bureau of Ordnance }}, p. 127.</ref>

Maxim developed and installed the first electric lights in a New York City building (the Equitable Life Building (New York City) at 120 Broadway) in the late 1870s.<ref name=nyt/> However, he was involved in several lengthy patent disputes with [[Biography:Thomas Edison|Thomas Edison]] over his claims to the lightbulb. One of these actions regarded the incandescent bulb, for which Maxim claimed that Edison was credited by means of his better understanding of patenting law. Maxim claimed that an employee of his had falsely patented the invention under his own name, and that Edison proved the employee's claim to be false, knowing that patent law would mean the invention would become public property, allowing Edison to manufacture the lightbulb without crediting Maxim as the true inventor.{{citation needed|date=November 2016}}

===Maxim gun===
[[File:Maxim, Cassier and Smith with Machine Gun for Germany - Cassier's 1895-04 (cropped).png|thumb|upright|Image from the April 1895 edition Cassier's Magazine, showing Hiram Maxim and the Maxim gun, along with Louis Cassier and J. Bucknall Smith]]
Maxim was reported to have said: "In 1882 I was in Vienna, where I met an American whom I had known in the States. He said: 'Hang your chemistry and electricity! If you want to make a pile of money, invent something that will enable these Europeans to cut each others' throats with greater facility.'"<ref name=nyt>Malcolm Brown [https://query.nytimes.com/gst/fullpage.html?res=9B0CEFDE1E38F935A15752C1A963948260&sec=health&spon=&pagewanted=all 100 years of 'Maxim's Killing Machine'] ''New York Times'', 26 November 1985.</ref>

As a child, Maxim had been knocked over by a rifle's recoil, and this inspired him to use that recoil force to automatically operate a gun. Between 1883 and 1885 Maxim patented gas, recoil and blowback methods of operation. After moving to England, he settled in a large house formerly owned by Lord Thurlow in West Norwood where he developed his design for an automatic weapon, using an action that would close the breech and compress a spring, by storing the recoil energy released by a shot to prepare the gun for its next shot. He thoughtfully ran announcements in the local press warning that he would be experimenting with the gun in his garden and that neighbours should keep their windows open to avoid the danger of broken glass.<ref>Ben Weinreb & Christopher Hibbert, ''The London Encyclopedia'', {{ISBN|0-333-57688-8}} ''Serbia House''</ref>

Maxim founded an arms company with financial backing from Edward Vickers to produce his machine gun in Crayford, Kent, which later merged with Nordenfelt. Subsequently, part of the Barrow Shipbuilding Company purchase by [[Company:Vickers|Vickers]] Corporation in 1897, formed 'Vickers, Son & Maxim'. Their improved development of the Maxim gun design, the [[Engineering:Vickers machine gun|Vickers machine gun]], after Maxim's resignation from the board in 1911 on his 71st birthday, was the standard British machine gun for many years. With arms sales led by Basil Zaharoff, variants of the Maxim gun were bought and used extensively by both sides during [[Social:World War I|World War I]].

In his later years Maxim became profoundly deaf, as his hearing had been damaged by years of exposure to the noise of his guns.<ref>Action By Sir Hiram Maxim, ''The Times'', 16 January 1915.</ref>

===Flying machines===
[[Image:maxim.gif|thumb|right|Maxim's flying machine]]
Maxim's father had earlier conceived of a helicopter powered by two counter-rotating rotors, but was unable to find a powerful enough engine to build it. Hiram first sketched out plans for a helicopter in 1872, but when he built his first "flying machine" he chose to use wings.  Before starting design work, he carried out a series of experiments on aerofoil sections and propeller design, at first using a [[Physics:Wind tunnel|wind tunnel]] and later building a whirling arm test rig.<ref>{{cite book |last=Penrose |first=Harald<!--Harald is not a typo--> |title=British Aviation: The Pioneer Years |location=London |publisher=Putnam |date=1967 |pages=22–23 }}</ref> Construction started in 1889 of a {{convert|40|ft|m|adj=mid|-long}} craft with a {{convert|110|ft|m|adj=mid}} wingspan that weighed 3.5 tons, powered by two lightweight naptha-fired {{convert|360|hp|adj=mid}} [[Physics:Steam engine|steam engine]]s driving two {{convert|17|ft|m|adj=mid|-diameter}} laminated pine propellers.<ref>{{harvnb|Penrose|1967|p=25}}</ref>

Conceived of as a test rig, the machine ran on an {{convert|1800|ft|m|adj=mid}} length of rail track which Maxim laid down for the purpose at his home, Baldwyn's Park Mansion, Baldwyn's Park in Bexley.<ref>{{cite web|title=Baldwyn's Park Mansion|url=http://www.newsshopper.co.uk/news/bexley/322679.inventors_mansion_in_line_for_makeover/|website=News Shopper|date=11 February 2002 |access-date=23 February 2017}}</ref> The initial intention was to prevent the machine from lifting off by using heavy cast-iron wheels, but after initial trials, Maxim concluded that this would not suffice, and so the machine was fitted with four wheeled outriggers which were restrained by wooden rails {{convert|13|ft|m}} outside the central track.<ref>{{harvnb|Penrose|1967|pp=33–4}}</ref> In trials in 1894, the machine lifted and was prevented from rising by the outriggers.<ref>{{cite news | newspaper = The Times | date = 25 November 1916 | title = Death of Sir Hiram Maxim.

====Captive Flying Machines====<!--Proper name -- capitalisation is correct-->
[[Image:Hiram Maxim Captive Flying Machines.jpg|thumb|right|The Sir Hiram Maxim Captive Flying Machines operating at Blackpool Pleasure Beach in 2006]]
To both fund his research into flight and to bring attention to the notion of flight, Maxim designed and built an amusement ride for the Earl's Court exhibition of 1904. The ride was based on a test-rig he had devised for his research, and consisted of a large spinning frame from which cars hung captive. As the machine spun, the cars would be swung outward through the air, simulating flight. The ride was similar to the later Circle Swing ride, made popular in the US by renowned roller-coaster designer [[Biography:Harry Traver|Harry Traver]].

Maxim originally intended to use primitive aerofoils and wings to allow riders to control their flight, but this was outlawed as unsafe. As a result, Maxim quickly lost interest in the project, declaring the adapted ride as "Simply a glorified merry-go-round". Nevertheless, his company built several more rides of various sizes at The Crystal Palace and various seaside resorts including Southport, New Brighton, and Blackpool, all of which opened in 1904. Originally, Maxim had intended to build only two, but a lengthy breakdown on the original Earl's Court ride forced him to build more to make the venture profitable. He had plans for further variations of the ride but his disillusionment with the amusement business meant that they were never realised.

Although he expressed regrets about the whole project, the rides were held in high regard within the amusement industry and the Blackpool ride still operates to this day as part of what is now the Pleasure Beach amusement park. Along with the same park's similarly historic river caves, it is the oldest operating amusement ride in Europe. The Flying Machines has the distinction of being virtually unchanged from Maxim's original design. The Blackpool ride's name is now usually abbreviated to the "Flying Machine" or "Flying Machines", although the full name, "Sir Hiram Maxim's Captive Flying Machines", is given at the ride entrance.

In 2001, Disney California Adventure Park opened, featuring the Golden Zephyr, a modern-day recreation of the Traver version of the ride. The ride itself is much smaller than the Blackpool version, with cars swinging out at a much smaller angle. Nevertheless, engineers from Disney visited Blackpool to inspect the Maxim ride (the only example of either version still standing) to help design their ride.

==Grahame-White, Blériot, and Maxim Company==
In 1911, Maxim headed the newly formed [[Engineering:Grahame-White|Grahame-White]], Blériot, and Maxim Company, founded with the two aviators and two hundred thousand pounds of capital.<ref>{{cite news |title=Maxim Leads Air Company. Grahame-White, Bleriot and Maxim Company with $1,000,000 Capital. |quote=Sir Hiram Maxim, who has just resigned from the ordnance firm with which his name has been for so long connected, will be the Chairman of a new company to be known as the Grahame-White, Bleriot, and Maxim Company, limited, with a total authorized capital of 200,000 ($1,000,000.) |newspaper=New York Times |date=29 March 1911 |page=1 |url=https://query.nytimes.com/gst/abstract.html?res=9B00E6DB1439E333A2575AC2A9659C946096D6CF}}</ref>
He had hoped to produce military aircraft capable of scouting or dropping a {{convert|500|lb|kg|adj=mid}} bomb, but his failing health and financial difficulties with his other enterprises restricted his ability to develop this enterprise before his death.<ref>"Sir Hiram Maxim's Resignation. The Inventor And Aviation", ''The Times'', 23 March 1911.</ref>

== Philosophy ==
In addition to his engineering endeavors, Maxim, a lifelong atheist<ref>{{cite book|title=A Rationalist Encyclopaedia: a book of reference on religion, philosophy, ethics, and science|year=1950|publisher=Watts|page=384|author=Joseph McCabe|edition=2|quote=He was a member of the firm of Vickers' Sons and Maxim.

This book was addressed to Li Hung Chang (also spelled Li Hongzhang and Li Hung-chang) and endeavored to address a belief that "The Chinese were generally puzzled as to how it was possible for people who are able to build locomotives and steamships to have a religion based on a belief in devils, ghosts, impossible miracles, and all the other absurdities and impossibilities peculiar to the religion taught by the [[Religion:Missionary|missionaries]]."<ref name="Scrapbook Foreword">''Li Hung Chang's Scrapbook'', Foreword, p. x.</ref>

Maxim held European missionaries in China in low esteem, for reasons described in the scrapbook. He stated "...it was my aim, in compiling for His Excellency a scrap-book with explanatory notes, to put the Chinaman right in this respect. I wished to show that we were not all fools."<ref name="Scrapbook Foreword" /> His scrapbook comprised some 400 pages with 42 illustrations, presenting his views on The Nature of Christianity; Christianity in China; and his conclusions on subjects including Miracles, Spirituality, Faith; and the influence of the Bible on the civilization of Europe and America. He concluded his scrapbook with an appeal to the Missionaries and his thoughts on the reason for the failure of what he described as "Missionary Propaganda" in China.

==Honors==
Maxim was a Chevalier of the Legion of Honour; a Civil, Mechanical and Electrical Engineer; Member of the London Chamber of Commerce; Fellow of the Royal Institution; Member of the British Association for the Advancement of Science; Member of the British Empire League; and Fellow of the Royal Society of Arts.<ref name="Hiram Stevens Maxim 1913" />

==Emigration and knighthood==
In 1881, Maxim arrived in Britain to reorganise the London offices of the United States Electric Lighting Company.<ref>{{cite web|url=https://www.pbs.org/wgbh/theymadeamerica/whomade/maxim_hi.html|title=Who Made America|publisher=PBS}}</ref> His visits back to the United States became increasingly infrequent and, on 16 September 1899, Maxim became a naturalised British citizen.<ref>{{London Gazette

==Death==
[[Image:WNC Maxim.JPG|thumb|Gravestone of Sir Hiram Maxim]]

Maxim died at his home in Streatham, London on 24 November 1916 at the age of 76.<ref>{{Cite web|url=http://www.freebmd.org.uk/cgi/information.pl?cite=OSGw25ViVJ6unrlLfnAVuQ&scan=1|title=Index entry|access-date=10 October 2017|work=FreeBMD|publisher=ONS}}</ref><ref>{{London Gazette |issue=29892 |date=5 January 1917 |page=317}}</ref> He is buried in south London's West Norwood Cemetery with his wife and his grandson, Lt Colonel Maxim Joubert.

==Family==
His brother, Hudson Maxim, was also a military inventor, specializing in explosives. They worked quite closely together until later in life, when there was a disagreement on a patent for [[Chemistry:Smokeless powder|smokeless powder]]. The patent, Hiram claimed, had been issued under the name 'H. Maxim,' and that because of this, his brother was able to stake a claim as the powder being his own. Hudson was a skilled and knowledgeable man, and sold arms in the US, while Hiram worked mainly in Europe. Hudson had success in the States, which caused jealousy from Hiram (he lamented having a "double" of himself running around in the States). The jealousy and disagreements caused a rift between the brothers that would last the rest of their lives.<ref name="Hawkey 2001" />

Hiram Maxim married his first wife, the English-born Jane Budden, on 11 May 1867 in Boston, {{wipe|Massachusetts}}. Their children were: Hiram Percy Maxim; Florence Maxim, who married George Albert Cutter, and Adelaide Maxim, who married Eldon Joubert, Ignacy Jan Paderewski's piano tuner.<ref>{{cite news|title=Hiram Percy Maxim, Wireless Amateur No. 1, Defended Rights of Youth|date=23 February 1936|newspaper={{wipe|New York Times}} |quote=Radio amateurs, numbering more than 45,000 in the United States, are mourning the loss of a friend and faithful ally in the passing of Hiram Percy Maxim of Hartford, Connecticut. As an ardent wireless amateur Mr. Maxim is remembered by veteran experimenters of pre-war days by the musical tone of his quench spark gap which spelled out the call letters of his pioneer station.}}</ref> In 1875, the family moved to Fanwood, New Jersey, with Hiram joining the family on weekends.<ref>Maxim, Hiram Percy. [http://lateralscience.blogspot.com/2014/11/a-genius-in-family-by-hiram-percy-maxim.html ''A Genius in the Family''], Lateral Science. Accessed 6 August 2019. "We moved to Fanwood, New Jersey, in the spring of 1875. My father used to come out from New York on Saturday afternoons and remain with us until Monday morning."</ref>

His son Hiram Percy Maxim followed in his father's and uncle's footsteps and became a mechanical engineer and weapons designer as well, but he is perhaps best known for his early amateur radio experiments and for founding the American Radio Relay League. His invention of the "Maxim Silencer" for noise suppression came too late to save his father's hearing.<ref>{{cite magazine|url=http://www.time.com/time/magazine/article/0,9171,742801,00.html|archive-url=https://web.archive.org/web/20070930103659/http://www.time.com/time/magazine/article/0,9171,742801,00.html|url-status=dead|archive-date=30 September 2007|title=Noise's Bogeyman|date=4 January 1932|access-date=21 August 2007|magazine={{wipe|Time (magazine)}}|quote=While mental hygienists, efficiency experts and city officials have been bewailing the maddening effects of city noise, Hiram Percy Maxim has been manufacturing noise mufflers at Hartford, Conn.

Most of these short stories are entertaining; they give a reader an insider's (and a child's) view of the man's personal and family life.<ref>{{cite book|title=A Genius in the Family|last=Maxim|first=Hiram Percy|publisher=Michael Joseph Ltd.|year=1936|location=London}}</ref>  ''So Goes My Love,'' a film loosely based on these memoirs and starring Don Ameche and Myrna Loy, was released in 1946.

Hiram Maxim married his secretary and mistress, Sarah, daughter of Charles Haynes of Boston, in 1881. It is not clear if he was legally divorced from his first wife at this time. The marriage was registered again in Westminster, London in 1890.<ref>{{Cite web|url=http://www.freebmd.org.uk/cgi/information.pl?cite=odlOILg14gBCqvAm3q2P%2Bw&scan=1|title=Index entry|work=FreeBMD|publisher=ONS|access-date=10 October 2017}}</ref><ref>{{Cite web|url=http://www.freebmd.org.uk/cgi/information.pl?cite=HRdsH%2FflIig0oETHEJBXZQ&scan=1|title=Index entry|work=FreeBMD|publisher=ONS|access-date=10 October 2017}}</ref>

A woman called Helen Leighton brought a case against Maxim, claiming that he had married her in 1878 and that "he was knowingly committing bigamy" against his current wife, Jane Budden. She claimed further that Maxim had fathered a child named Romaine by her. The case was eventually dropped, being settled for under $1,000 (the original amount asked for was $25,000), and Maxim put behind him the near public humiliation the case caused. In October 1898, Helen Leighton again brought charges against Maxim for bigamy and abandonment in Poughkeepsie, New York.<ref>{{cite web|url= https://chroniclingamerica.loc.gov/lccn/sn85066387/1898-10-09/ed-1/seq-3/print/image_681x648_from_3276%2C3907_to_5099%2C5643/
