Matthew Piers Watt Boulton

Early life

Boulton was born 22 September 1820 at Mose Old Norton, Staffordshire, England, to Matthew Robinson Boulton (8 August 1770 – 16 May 1842) and Mary Anne Wilkinson (27 November 1795 – 7 June 1829). He was baptized at St. Mary's Church, Handsworth, Staffordshire on 9 November 1820. M. P. W.'s ancestors can be traced back to John Bolton (his surname missing the u, which was included one or two generations later) of Lichfield, Staffordshire, who married (the later-to-be wealthy) Elizabeth, daughter of Matthew Dyott of Stichbrooke, Staffordshire in the late 15th century. John Bolton is believed descended from, possibly a grandson of Robert Bolton (1572 – 19 December 1631), rector of Broughton, Northamptonshire in 1609 until his death.

M. P. W. Boulton's immediate family included two younger brothers (both whom survived childhood but died unmarried) as well as three sisters and eight cousins. His brother-in-law, James Patrick Muirhead (1813–1890, husband to Boulton's elder sister Katharine Elizabeth, 1816–1890), would become James Watt's biographer.

Boulton's grandfather Matthew Boulton and James Watt had perfected the steam engine during the 1770s which soon set off the Industrial Revolution in England, and later the rest of the world. Matthew Piers Watt was named after his grandfather as well as his grandfather's close business partner, James Watt who had jointly created the Soho Foundry which employed their engines. Boulton's second given name also reflected the family of his great-grandmother, the Piers of Chester, Bull Ring, Birmingham.

In 1815–1816 M. P. W.'s father, Matthew Robinson Boulton, bought the 3,250 hectares (8,000 acres) Great Tew Estate and manor in the civil parish of Cotswold Hills in Oxfordshire. In 1825 he added a Gothic Revival library to the east end of the manor house, and by the middle of the 19th century the Boulton family had a large Tudor style section designed by F.S. Waller added to the west end. The Great Tew Estate would remain with Boulton's immediate family until M. P. W.'s son Matthew Ernest Boulton died without heirs in 1914, after which it was eventually inherited by a more distant relative.

Boulton's early education included instruction at a private school in Royal Leamington Spa (simply called Leamington) run by Reverend Atwood, the Vicar of Kenilworth. There were but six boys in this school with a good measure of religious instruction. He attended with his younger brother Hugh William (1821–1847) who would die at age 26, and with Francis Galton, later Sir Francis Galton, the brilliant English polymath who became his friend and remained so through Cambridge.

Family life

Boulton was married twice; his first marriage on 27 November 1845 was to Frances Eliza Cartwright (b. Northamptonshire 1817 – d. Great Malvern, Worcestershire 1864), the daughter of Lieutenant-Colonel William Ralph Cartwright and his second wife Julia Frances Aubrey. Her father served as a Tory politician and sat in the British House of Commons between 1797 and 1846. Boulton's first marriage produced two daughters, Marianne Aubrey (sometimes Mary Anne Audrey, b. London, 1854–1934) and Ethel Julia (b. Tew, 1858–1924).

After selling Soho House and his father's mint facility in 1850, Boulton retired to his family's manor and estate of Great Tew, in the Oxfordshire village of the same name, and also living in London. An 1851 census listed him at the former as a landed proprietor, along with a nephew, Thomas Robert Cartwright (age 20), and nine servants.

Following the death of his first wife Frances Eliza in 1864, Boulton remarried with Pauline Gleissberg (b. Germany, 1837–1911), daughter of Ernst Gleissberg, dean of the city of Cannstatt in the German kingdom of Württemberg. Together they had four children: Clara Gertrude (later to be Lady of the Manor of Great Tew, b. Knightsbridge, 1868–1954), his first son Matthew Ernest Kensington (b. Paddington, 1870–1914), Pauline Margaret (b. Switzerland, 1872–1918) and Frederick Montagu (b. Great Tew, 1875–1912).

Later years: career, publications and scientific works

Boulton became a Justice of the Peace, Deputy Lieutenant, and High Sheriff of Oxfordshire before the age of 30. He was part of the landed gentry due to his family's holdings at Tew Park, and the Great Haseley Court estate and manor that M. P. W. later purchased in Tetworth, Gloucestershire in 1880. Boulton improved the Tew estate by enlarging its grand three-story manor house, adding another garden and refining its grove.

With the death of his father in 1848, he inherited the large fortune created by both his father's and grandfather's enterprises, permitting him, his large household and his relatives a comfortable life. Up to 11 servants were employed to administer to his manor and estate. Boulton's inheritance made him wealthy, but he had little desire to continue his family's businesses which he subsequently closed, disposing of their assets by sale. His financial independence allowed him to pursue studies and writings as a philosopher-scientist on a wide variety of subjects. Among them were at least two pamphlets in the early 1860s refuting the authenticity of purported 18th-century photographs; verse translations of the classics including Homer's Iliad, Virgil's Æneid and other classical works during the mid-1870s; papers on metaphysics from the late 1870s, and as well two pamphlets on solar energy written in the early 1890s. He earned over a dozen patents for multiple inventions, many of them for aircraft propulsion systems. At least one patent was assigned to George Westinghouse, Jr, the American industrial tycoon.

His financial independence allowed him not to pursue any particular career aggressively. He was described as reclusive to the point that his "wide knowledge and sterling qualities were known only to a few". While others of wealth and ability often sought greater wealth, notability and positions of power, Boulton was to eventually become notable for being unnotable. In his lifetime he had "...no wish to attract the attention of his contemporaries".

Kenyon College Professor of History Bruce Kinzer's 2009 biographic sketch of Boulton, possibly the only one ever published, posited that "Boulton has not posthumously gained the recognition he never sought during his lifetime." The philosopher-scientist-inventor's non-notability extended to missing entries in Boase's Modern English Biography, the Dictionary of National Biography (where he was one of only five members of the Metaphysical Society who did not appear in it) and the later Oxford Dictionary of National Biography.

Death and legacy

M. P. W. Boulton died in London on 30 June 1894 at age 73. This was soon noted by The Times which wrote in his obituary that he was:

... a most gifted member of a gifted family, the inheritor of a large fortune, and highly cultured; but, being naturally a recluse, with no care for self-assertion, his wide knowledge and sterling qualities were known only to a few

After Boulton's death his eldest son Matthew retained the Great Tew Estate until his own death, still single, in 1914, after which the estate fell into general disrepair, unused for a number of decades. Boulton's great-nephew Major Eustace Robb renovated the estate and lived there from 1952 until his demise in 1985.

Tribute

Boulton Peak is a mountain summit at the southeast side of Curtiss Bay, about 9 kilometres (5.6 mi) south of Cape Andreas in Antarctica. It was mapped from air photos taken between 1955 and 1957 and named by the UK Antarctic Place-Names Committee in 1960 to honour Boulton for his invention of the aileron.

Aeronautical works

In 1868, long before the advent of powered aircraft flight – and within a decade of the birth of both Orville and Wilbur Wright – Boulton patented the first aileron. The aileron system he created was to be actuated by either a hand-operated control (not illustrated on the patent's drawings) or by an automatic pendulum control device (depicted on the patent's drawing sheet), with the intended function of a single-axis autopilot. Boulton's inspiration for a lateral flight control device has been attributed to French Count Ferdinand Charles Honore Phillipe d'Esterno, whose detailed analysis of flapping and soaring bird flight, Du Vol des Oiseaux (On the flight of birds) was published as a pamphlet in 1864. Although Boulton's prescient aileron control system was fully functional, he, as did almost everyone of his era, lacked a detailed understanding of aerodynamics, and an airplane he designed never achieved flight.

Ailerons are a key device for the lateral flight control of airplanes to enable their safe flight. They are still in almost universal use in the present day by civilian and military aircraft, and even on the most sophisticated jetliners. In 1873, five years after Boulton's aileron patent, the French military engineer and aircraft designer Charles Renard built and flew at St.-Eloi, near Arras, a small unmanned multi-wing glider incorporating ailerons (which he termed "winglets") on each side of its body, controlled by Boulton's pendulum control single-axis autopilot device with a design layout that closely matched the patent.

Boulton's Letter's Patent specifications were sealed on 4 August 1868 and the complete patent was backdated to its application date of 5 February 1868. His British patent, the 392nd one completed in 1868, was issued more than 35 years before ailerons were 'reinvented' in France, and ailerons were later repatented in the United States by Glenn Curtiss of the Aerial Experiment Association in about 1911. Boulton's 1868 patent became forgotten and lost from sight until the same time, a few years before they came into general use in 1915. Aviation historian C. H. Gibbs-Smith acknowledged Boulton's priority of invention, stating that if the 1868 patent had been revealed at the time of the Wright brothers' legal filings, they might not have been able to claim the priority of invention for the lateral control of flying machines.

Although Boulton had described ailerons in 1864 and then patented them in 1868, no one is known to have used them in manned aircraft flight until Robert Esnault-Pelterie's glider, 36 years later in 1904 (Renard's 1871 glider flights using pendulum controlled "winglets" were unmanned). Esnault-Pelterie, a French aeronautical engineer, built a Wright brothers-style biplane glider that year, which had first used their wing warping design that he had also copied, but the glider's control in flight was found to be poor and was then changed over to ailerons, although another source states the changeover was due to his view that wing warping was structurally dangerous.

Patent description of ailerons

Boulton's description of his aileron control system was both clear and complete. It was "the first record we have of appreciation of the necessity for active lateral control as distinguished from [passive lateral stability].... With this invention of Boulton's we have the birth of the present-day three torque method of airborne control" as was praised by Charles Manly. This was also endorsed by C. H. Gibbs-Smith.

The patent's actual wording of ailerons reads (page 16, from line 8):

For the safety of aerial vessel it is important to provide a controlling power not only to direct their horizontal and vertical course, but also to prevent their turning over by rotating on the longitudinal axis. A certain stability of the kind desired is afforded by using an extended surface whose sides make an angle from the axis upwards ... But it is desirable to provide a more powerful action preventing [rolling] rotation of the body in this direction. For this purpose a rudder of the following construction may be adopted:—Vanes or movable surfaces are attached to arms projecting from the vessel laterally or at right angles to its length. When these vanes are not required to act they present their edges to the front, so as to offer little resistance to the vessel's movement, but if the vessel should begin to rotate [roll] on the longitudinal axis the vanes are moved so as to take inclined positions, those on the ascending side of the vessel being caused to rotate to such an inclination that the air impinging upon them exerts a pressure downwards, while those on the descending side are so inclined that the air impinging upon them exerts a pressure upwards, thus the balance of the vessel is redressed and its further rotation prevented. The vanes may be moved by hand or by self-acting mechanism.....

Three figures (No. 5–7) of his aileron system were provided on the patent's attached drawing sheet, and on page 19 his explanation of the drawings reads (page 19, from line 22):

Figure 5 represents a transverse section of a plane fitted with rudders constructed according to my Invention to prevent its turning over on an axis in its line of motion through the air. a is a section of the plane which is supposed to have taken a position inclined to the horizon; b and c are two vanes mounted on axes one at each side of the plane, so that it can be turned round like a throttle valve...."

Ongoing controversy

There are still conflicting claims today over who first invented the aileron. Other 19th century engineers and scientists, including Charles Renard, Alphonse Pénaud, and Louis Mouillard, had described similar flight control surfaces, possibly serving as further inspiration to Boulton aside from Count d'Esterno. Another technique for lateral flight control, wing warping, was also described or experimented with by several people including Jean-Marie Le Bris, John Montgomery, Clement Ader, Edson Gallaudet, D. D. Wells, and Hugo Mattullath. Aviation historian C. H. Gibbs-Smith wrote that the aileron was "... one of the most remarkable inventions ... of aeronautical history, which was immediately lost sight of".

In an apparent oversight by the U.S. Patent Office, the Wright brothers, on their second attempt, obtained a patent in 1906, not for the invention of an airplane (which had already existed for a number of decades in the form of gliders) but for the invention of a system of aerodynamic control that manipulated a flying machine's surfaces, including lateral flight control. They did so despite rudders, elevators and ailerons having been invented long before their efforts began, and then aggressively sued other aircraft builders worldwide for failure to pay them licensing royalties on the basis of the lateral flight control described in their expansive 1906 patent. Irrespective of such controversies it was Boulton, indisputably, who was the first to patent ailerons in 1868. The ailerons used by Esnault-Pelterie in 1904 followed Boulton's concept, although it is unknown whether he had studied the 1868 work, or if he had reinvented them independently.

Other aeronautical, gas turbine and engine design research

In 1864 Boulton looked at the problems of combustion at constant pressure, in connection with the operation of an industrial gas turbine. His British patent, No. 1636 of 1864, contains points of interest. He realized that the high velocity of the gas jet exiting his combustion chamber nozzle offered a practical difficulty, and proposed to remedy this by the use of successive induced jets of increasing volume and consequently lower velocity. This was shown in his drawing, with gases being delivered through collinear nozzles of increasing diameter, with the outer nozzles operating at increased gas volumes with reduced velocities, similar to the exhaust of a high-bypass turbofan jet engine.

Another method proposed by Boulton for maintaining combustion at constant pressure was shown with gas burned in an inverted chamber under water, the products of combustion passing up through the water between the baffle plates and the mixed gases and steam being later delivered to a turbine. He went on to file a number of patents related to his gas turbine research (see patents).

Boulton also attempted to build an ornithopter, an aircraft which would create lift by the movement of its articulating wings. A manned ornithopter was later created in 2006 when teams at the University of Toronto Institute for Aerospace Studies (UTIAS) achieved a working design with large flapping wing areas. With assist from a jet engine it only flew for about 300 meters on its only flight.

Family connection to other aviation works

Besides Boulton's invention of a primary flight control, the aileron, the family name may also be associated with the well known British firm that provided wartime aircraft production as Boulton Paul Aircraft. Boulton Paul Aircraft Ltd was a British aircraft manufacturer that was created in 1934, although its start in aircraft manufacturing began earlier in 1914, and lasted until 1961. The company mainly built and modified aircraft under contract to other manufacturers, but had a few notable designs of its own, such as the Boulton Paul Defiant.

The company's origins date back to a Norwich ironmonger's shop founded in 1797. William Staples Boulton joined the Norfolk ironworks firm of Moore & Barnard in 1844. By 1870 William had been elevated to a partner and the firm was renamed to Barnard & Boulton, later becoming Boulton & Paul Ltd. The latter firm began its construction engineering division in 1905. In the early 1900s, Boulton & Paul became a successful general manufacturing firm, also starting an aircraft production operation in 1914–1915. The aircraft manufacturing division was spun off from the main construction business in 1934, subsequently moving to Wolverhampton.

Pseudonymous works

Although no definitive proof is known to exist that Boulton was also published under the pen name M. P. W. Bolton, researcher and author Alan Brown wrote in The Metaphysical Society: Victorian Minds in Crisis, 1869–1880, that Boulton was also sometimes spelt as 'Bolton'. Brown was perhaps convinced of that since no biographical information exists for any 'M. P. W. Bolton', Bolton was, in fact, Boulton's pseudonymous pen name. Somewhat intriguingly, Boulton's younger brother, Montagu Boulton (1824–1849), was admitted to Cambridge University's Inner Temple (a law society) as "Matthew Bolton" in October 1844. Additionally, M. P. W.'s distant ancestors' surnames omitted the 'u', from their spelling. That included John Bolton of Lichfield, Staffordshire, who is believed descended from, possibly a grandson of Robert Bolton (1572–1631), rector of Broughton, Northamptonshire.

Under the alternate 'Bolton' spelling the British Museum lists several philosophical works (all published by Chapman & Hall, which had also published most of Boulton's works), including:

Examination of the Principles of the Scoto-Oxonian (1861);

Reply to a critique in the Saturday review on the Scoto-Oxonian philosophy (1862);

Letter to T. Collyns Simon, Esq., Author of The Philosophical Answer to Essays and Reviews (1863);

Inquisitio Philosophica: An Examination of the Principles of Kant and Hamilton (1866);

Examination of the Principles of the Scoto-Oxonian Philosophy: with Replies to Objectors (1869).

Several of the Bolton writings fiercely attacked the theological positions expounded by Scottish philosopher Sir William Hamilton and the metaphysician Henry Longueville Mansel, who both argued that God was "infinite" and "absolute". One possible reason for the alternate pen name in confronting authority figures may then have been that of deniability. An edition of John Stuart Mill's Examination of Sir William Hamilton's Philosophy later led the English political radical George Grote to examine Bolton's Inquisitio Philosophica, and prompted Mill to write that its author "is a scholar, well read in history of philosophy and.... [shows] that he holds with the inductive school, both in their philosophy and in its consequences". Mills thought the work's author an "acute thinker" and Inquisitio an "able work".
