He was the son of John Dollond, a Huguenot silk weaver and started business as an optician in 1750. He was joined by his father in 1752 until his death in 1761, and then by his brother, John, until his death in 1804. The family business was continued by Peter Dollond's nephew, George Huggins, who changed his surname to Dollond.

The firm became one of the largest makers and suppliers of scientific and optical instruments and continued trading under various guises throughout the 19th and 20th centuries. The sympiesometer was invented by Alexander Adie of Edinburgh in 1818 and is essentially an improved version of Robert Hooke's thermobarometer which was subject of a paper presented to the Royal Society in 1668. The instrument works by having a syphon tube filled with liquid open to the air at one end and with trapped gas at the other (sulphuric acid and hydrogen were used in later sympiesometers). As barometric pressure increases the liquid will be forced down the tube causing the gas to be compressed, resulting in a change in level in the tube; however the volume of the gas changes with temperature so before a reliable reading can be taken the instrument would first need to be calibrated by adjusting the position of the movable barometer scale in relation to the temperature scale behind to reflect the reading provided by the thermometer. The sympiesometer was conceived by Adie as an alternative to the mercury marine barometer as it was smaller and believed to be less susceptible to the motion of a vessel at sea.

Nicholas Goodison in ENGLISH BAROMETERS 1680-1860 notes that John Bennett worked up until 1768 and illustrates an undated trade card indicating that he was located at 'The Globe, Crown Court, between St. Ann's, Soho, and Golden Square'. Bennett was a fine maker who held warrants to three members of the Royal Family and most likely had a working relationship with the eminent scientific instrument maker Jonathan Sisson.

A RARE GEORGE III MAHOGANY HODOMETER OR WAYWISERDOLLOND, LONDON, CIRCA 1800With 31.5 inch diameter wheel bound with an iron tyre and with six tapered spokes around a brass hub engaging with take-off gearing contained within the left hand fork of the handle assembly, the right hand fork incorporating a hinged section to allow removal of the wheel with locking via a knurled brass screw, the upper section with inverted 7.25 inch circular silvered register engraved Dollond, London to centre within concentric inner scale calibrated in Roman numeral Miles (I to X) and Arabic Furlongs (0 to 8 for each mile) to be read by the shorter of the two blued steel hands within outer scales calibrated in Poles (0 to 40) and Yards (0 to 220) to be read by the longer hand, set behind a hinged glazed circular moulded wooden bezel beneath elaborate yoke-shaped handle.137cm (54ins) high overall, 30.5cm (12ins) wide at the handle.  Provenance:Private Collection. Peter Dollond is recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1680-1860 as born 1730 and died 1820. He was the son of John Dollond, a Huguenot silk weaver and started business as an optician in 1750. He was joined by his father in 1752 until his death in 1761, and then by his brother, John, until his death in 1804. The family business was continued by Peter Dollond's nephew, George Huggins, who changed his surname to Dollond. George Dollond became instrument maker to William IV and Queen Victoria, exhibited at the Great Exhibition in 1851 and died 1856. The firm became one of the largest makers and suppliers of scientific and optical instruments and continued trading under various guises throughout the 19th and 20th centuries. The current lot would have been a particularly valuable instrument for surveyors charged with creating maps and plans during the latter years of the 18th century. The importance of the instrument's role is reflected in the quality of its construction with the dial in particular being finely engraved and finished. When reviewing comparable surviving instruments of this type it becomes clear that different makers such as Dollond, Thomas Rubergall, William Frazer, and W. and S. Jones appear to have sold essentially identical instruments. This would suggest that they were probably made in one workshop who then supplied them to various makers for retail. One possible candidate for the supplier would be the workshop established by George Adams, as several earlier variants of this design by him are known including an example in the King George III collection housed at The Science Museum, London. This suggests that Adams was used to making such instruments hence was best suited to supply them in reasonable numbers to other makers.  

Y A RARE GEORGE V SHIBAYAMA INSECT DECORATED SILVER CARRIAGE TIMEPIECETHE CASE BY A. AND J. ZIMMERMANN LIMITED, BIRMINGHAM 1911 The French rectangular eight-day single train movement with platform lever escapement regulated by sprung monometallic balance, with integral winder to backplate stamped with standing lion trademark for Duverdry and Bloquel, the 2 inch circular white enamel Roman numeral dial with blued steel spade hour hand set behind a convex glass within moulded bezel, the rectangular case with hinged C-scroll carrying handle over front and sides inlaid in mother-of-pearl, amber, abalone and other materials with random crawling insects incorporating engraved legs and antennae and with very small Japanese character signature to lower right hand corner of the front panel, the front also with canted surround to the fascia and the rear with conforming hinged door, on disc feet, Hallmarks for London 1911 makers A. &. J. Z within a shield.The clock 11.5cm (4.5ins) high with handle down, 7.5m (3ins) wide, 5.7cm (2.25ins) deep.  The firm of A. and J. Zimmermann Limited were a firm of silversmiths mostly specialising in small decorative items who worked from Regent Street, Birmingham from 1899 until 1929 when they were placed into voluntary liquidation. The clockmaking factory of Duverdry and Bloquel is noted by Leigh Extence as originally founded by Albert Villon in the town of Saint-Nicolas-d'Aliermont in 1867. Paul Duverdry joined the firm as a director in 1887 followed by Joseph Bloquel in 1910. The execution of Shibayama 'insect' decoration of the current lot would have been undertaken by a specialist Japanese craftsman resulting in a highly unusual luxury product. A similar but much smaller timepiece, with decoration apparently executed by the same Japanese craftsman into a silver case by Charles and Richard Comyns, London, was sold in these rooms FINE CLOCKS, BAROMETERS & SCIENTIFIC INSTRUMENTS 2nd March 2022 (lot 196) for £3,800 hammer.

Purchased at Christie's, London sale 500 Years: Decorative Arts, Europe 23rd September 2010 (lot 144) for £3,881.25. John Whitehurst (I) was born in Congleton, Cheshire in 1713, he was apprenticed as a clockmaker to his father (of the same name) before setting up business in Derby in 1736 - the same year he installed a turret clock to the newly completed Guildhall. He was an accomplished maker and scientist who had a particular interest in geology. He moved to London in 1780 in order to take up position at the Royal Mint as 'Stamper of the Money Weights' as well as pursue his scientific interests. He was founder member of the Lunar Society and was elected to the Royal Society in 1783. He died in 1788 leaving the Derby clockmaking business to his nephew also called John (II) who in-turn took his son of the same name (John III) into partnership in 1809. The firm traded as 'Whitehurst & Son' until 1834 when the business reverted to just 'Whitehurst' on the death of John (II). The business continued under the Whitehurst name until the death of John (III) in 1855 when it was sold to Roskell of Liverpool who subsequently wound-up operations in 1862. However, a former employee, John Smith, resurrected the business which is still trading today as 'Smith of Derby'.  John Whitehurst (I) is known for his distinctive design of angle barometer, an example of which was sold in these rooms in the THE BANFIELD COLLECTION OF BAROMETERS 4th September 2007 (lot 125) for £8,000 hammer. His son was one of the first to make wheel barometers, with his earliest models constructed with a Classical column forming the upright above the dial (see Goodison, Nicholas ENGLISH BAROMETERS 1680-1860 page 284, Plate 193). Condition Report: Barometer is generally in good original untouched condition. There is currently no siphon tube fitted (hence is not in working order) however the pulley assembly and recording pointer mechanism are present and in working order. The dial is in fine condition with slight oxidation/mellowing to the silvering only; the glass has probably been reset as the plaster which secures it to the bezel appears relatively fresh. The thermometer is in fine original working condition. The case is essentially untouched retaining fine old surface. The only notable faults are two vertical shrinkage cracks (from movement within the carcass) to each side the lower (drop) section and a small veneer patch repair to the lower edge. Otherwise faults are very much limited to minor age-related bumps, scuffs and minor shrinkage. Condition Report Disclaimer

Table clock, reproduction of the Jeremias Metzger modelIn gilt and silvered metal, with chiseled, pierced and molded decorationThe dome-shaped top with edges conceals the bell and features rich pierced decoration with vegetal scrolls and hunting scenes inspired by Virgil Solis's engravings (Nuremberg, 1514-1562). The edges are decorated with winged horses and, crowning the dome, a full-round representation of the goddess Fortuna on a classically-inspired pedestalOn the sides, arranged between the various dials and on a background engraved with arabesque patterns and vegetal scrolls, there are five female figures in relief, each with an animal, possibly with allegorical significance alluding to the five sensesThe base is decorated in low relief with a military procession, depicting armed figures marchingThe main dial, flanked by astronomical and calendar subsidiary dials, includes a celestial astrolabe dial, a perpetual calendar indicating Saints' days, a Golden Number dial, and various scales associated with time measurement and astronomical cycles. These dials replicate the complexity of Renaissance examples but, like other 19th-century reproductions, are merely decorativeStructure flanked by Corinthian columns and ornamented with engraved inscriptionsMechanism present, of simple construction, characteristic of 19th-century reproductions of this modelEurope, 19th century(minor losses and wear; mechanism untested; key missing)29×19×12 cmThis model reproduces the famous astronomical clocks created by Jeremias Metzger (active c. 1563-1564), goldsmith and clockmaker from Augsburg. During the Renaissance, these complex mechanisms were valued for their technical sophistication and their scientific and astrological symbolism.The first reproductions of this model appeared between 1864 and 1865, during a period of great interest in Renaissance heritage and ancient scientific instruments. The process was driven by the development of electroplating, allowing the production of meticulous replicas of historical objects. The Viennese firm C. Haas & Co. was one of the pioneers in this process, creating copies for museums and collectors.These nineteenth-century replicas are distinguished by their high aesthetic fidelity, accurately replicating the intricate decoration of astronomical dials, inscriptions, and figurative elements. Although the astronomical and calendar dials are decorative, maintaining only an ornamental function, the mechanism preserves the time-keeping functionality.Today, these nineteenth-century examples are appreciated not only for their historical value but also for their quality of execution and collectible interest, representing a fusion between Renaissance mastery and nineteenth-century scientific and artistic revivalism.

Simms, F.R.A.S.' the the base of the image, depicting a seated gentleman next to a Smith Beck & Beck, No.1 folding microscope with Varly stage, image 155mm x 208mm, in modern card mountFrederick Walter Simms (24 December 1803 – 27 February 1865) was a British civil engineer, known for his association with the Greenwich Observatory. He was the brother of William Simms (1793–1860), who, alongside his partner Edward Troughton formed the company of scientific instrument makers Troughton & Simms.Before joining the Greenwich Observatory in 1830, Simms apprenticed as a surveyor and contributed to the Trigonometrical Survey of Ireland. His tenure at the Observatory began when Thomas Glanville Taylor departed for the Directorship of the Madras Observatory. By 1835, Simms' responsibilities, as listed by John Pond, included observations with the Zenith Tube alongside John Henry Belville, occasional work with other instruments, proofreading printed observations with Henry, and overseeing the publication process of the annual volumes of Greenwich Observations. While Pond commended Simms as "very able and diligent," he also noted irregularities in chronometer rates, which eventually led to expectations of retirement.Despite being paid a modest salary supplemented by earnings from navigation lessons and surveying tasks, Simms found the financial arrangement insufficient. His dissatisfaction culminated in his resignation on 21 October 1835, shortly after the arrival of the new Astronomer Royal, Airy. Airy, in his autobiography, remarked that Simms had hoped for the position of First Assistant, a role for which Airy deemed him unfit.Following his departure from the Observatory, Simms pursued a new career path as a railway surveyor and engineer. In 1836, Simms commenced his role as a resident engineer with the South Eastern Railway Company, embarking on various significant projects, including the construction of the Bletchingley and Saltwood tunnels. He authored several books on surveying and tunnelling and produced the 1838 Map of The Parish of Greenwich in the County of Kent for the Tithe Commissioners.In 1846, the East India Company, seeking to expand railway infrastructure in their territories, approached Simms to serve as their consulting engineer in India. Despite grappling with health issues exacerbated by the climate, Simms briefly sojourned in Mauritius before resuming his duties. Among his responsibilities was overseeing the comprehensive survey and mapping of Calcutta, primarily conducted by local assistants.Upon concluding his tenure with the East India Company, Simms returned to England in 1851, his health notably deteriorated due to the harsh conditions in India. He subsequently retired from active professional life.

Andreas Vesalius, Rufus of Ephesus & Girolamo Fabrizio d'Acquapendente,three books bound in contemporary velum on pasteboards with fabric ties, recent bookplate for 'Ex Libris lato Ivan Pozeg', as:Book1: Andreas Vesalius, Anatomia, 1604, Venice: Giovanni Antonio and Giacomo de Franceschis, 2 parts in 1 Vol. engraved title with Vesalius proforming a dissection surrounded by architectural boarder incorporating bodies in various staes of dissection, with tabel at base arranged with surgical instruments, minor Contemporary manuscript to some margins, light browning but generally very goodAndreas Vesalius (1514–1564), often hailed as the "Father of Modern Anatomy," was a pioneering Flemish anatomist and physician whose then groundbreaking work revolutionized the study of the human body. Educated at the University of Louvain and the University of Padua, Vesalius challenged the prevailing reliance on ancient texts by advocating for hands-on dissection and observation. His monumental work, De Humani Corporis Fabrica (1543), was a masterpiece of anatomical precision, featuring intricate illustrations that set a new standard for medical texts.Vesalius's insistence on empirical evidence over traditional authority laid the foundation for modern medical science. His dissections and detailed observations corrected many errors in Galenic anatomy, earning him both acclaim and controversy in his time. Later in his career, Vesalius served as court physician to Emperor Charles V and King Philip II of Spain. His work continues to influence medical education and anatomical research.Book Description:The 1604 edition of Anatomis by Andreas Vesalius is a significant publication that underscores his revolutionary contributions to anatomy. This folio volume is a refined and expanded work, incorporating Vesalius's earlier findings alongside updated insights that reflect the evolving understanding of human anatomy in the early 17th century.The text is richly illustrated with detailed woodcut engravings, showcasing Vesalius's approach to the study of the human body. Each anatomical structure is depicted with artistic precision and scientific clarity, making this edition a valuable resource for physicians and scholars of the period. The work includes sections on skeletal, muscular, and organ systems, accompanied by annotations that highlight both anatomical function and surgical relevance. Book 2: Rufus of Ephesus, with commentary by Fabius Paulinus, Universa Antiquorum Anatome, Tam Ossium, Quam Partium & Externarum, & Internarum, 1604, Published in Venice by Io. Antonium and Jacobum de FranciscisRufus of Ephesus was a physician and anatomist of the 1st century CE, whose contributions to medical science were foundational in antiquity. Active during the height of the Roman Empire, Rufus was noted for his studies in anatomy and clinical medicine. His works, which often integrated practical medical advice with philosophical insights, greatly influenced subsequent generations of physicians in both the Greco-Roman and Islamic worlds. His detailed anatomical observations, particularly on the human body’s internal organs, were a precursor to later advancements in anatomical studies.The 1604 edition was edited and expanded by Fabius Paulinus, a Renaissance scholar who brought Rufus’s works to a wider audience. Paulinus supplemented the original text with additional commentary and illustrations, translating some previously inaccessible Greek fragments into Latin for the first time, including sections from the writings of Soranus of Ephesus, another influential ancient physician.Book Description:This 1604 folio edition, Universa Antiquorum Anatome, is a landmark in anatomical literature. It presents the detailed anatomical knowledge of Rufus of Ephesus, supplemented with the scholarly additions of Fabius Paulinus. The text explores both external and internal structures of the human body, providing insights into ancient medical practices and observations. A key feature of this edition is the inclusion of a fragment from Soranus of Ephesus, newly translated into Latin, which discusses the anatomy and function of the uterus.The title page is adorned with an intricate engraving, symbolizing the union of classical learning and Renaissance scientific inquiry. Published in Venice by Io. Antonium and Jacobum de Franciscis, the work reflects the high standards of early 17th-century Venetian printing.Book 3: Girolamo Fabrizio d'Acquapendente, Le Opere Chirurgiche di Girolamo Fabrizio d'Acquapendente, 1683, Printed in Padua by Giacomo CadorinoGirolamo Fabrizio d'Acquapendente (1537–1619) was an Italian anatomist and surgeon, often called the "Father of Embryology." Educated at the University of Padua, Fabrizio was a key figure in the development of anatomical and surgical sciences during the Renaissance. His teaching and writings laid the foundation for modern anatomy and surgery, with particular contributions to understanding the venous system, the mechanics of the human body, and the development of embryos.Fabrizio was appointed as the chair of surgery and anatomy at Padua, where he taught for over 50 years. He is best remembered for his discovery of the valves in veins and his detailed studies of fetal development, which were milestones in medical science. His influence extended to many of his students, including William Harvey, who would later discover the circulation of blood. Fabrizio's writings and illustrations were groundbreaking, combining scientific rigor with artistic excellence.Book Description:This 1683 edition of Le Opere Chirurgiche is a comprehensive compilation of Girolamo Fabrizio d'Acquapendente’s surgical works, translated into Italian and expanded with additional commentary. Divided into two parts, the first section covers the treatment of tumors, wounds, ulcers, fractures, and other surgical conditions. The second part focuses on major surgical operations and includes insights into techniques and instruments used during the Renaissance.Printed in Padua by Giacomo Cadorino, this folio edition also features a supplement by Marco Aurelio Severino, providing a concise overview of surgical principles, making it an invaluable resource for surgeons and anatomists of the time.

BECQUEREL HENRI: (1852-1908) French physicist and engineer, the first person to discover radioactivity. Nobel Prize winner for Physics, 1903. A good autograph manuscript, unsigned, incorporating several explanatory drawings, two pages (written to the first and fourth sides of the bifolium), n.p., n.d. (circa 1895), in French. Becquerel's manuscript is entitled Historique des machines, and particularly concerns direct current dynamo-electric machines, and was most likely prepared as an aide-memoire for one of his first physics courses at the Ecole Polytechnique in Paris. Becquerel has listed the names of various famous inventors alongside the dates of their discoveries and summary notes, several with explanatory scientific drawings alongside, including Faraday ('1831 Anneaux de fer......d'une bobine'; Translation: '1831 Iron rings......a coil'), Pixii ('En 1832......aimants dans un disque bois mobile devant des bobines'; Translation: 'In 1832......magnets in a moveable wooden disk in front of coils'), Ritchie ('bobines mobiles'; Translation: 'moving coils'), Clarke, Nollet, Siemens, Wilde ('aimants et electro aimants'; Translation: 'magnets and electro magnets'), Ladd, Pacinotti, Gramme, Varley, Wheatstone, Alteneck and Edison. To the foot of the first page appear various scientific equations and drawings in pencil, most crossed through. A good manuscript featuring the names of many inventors and physicists who inspired and influenced Becquerel. Some very light, extremely minor age wear, VGMichael Faraday (1791-1867) English scientist who contributed to the study of electromagnetism and electrochemistry.Hippolyte Pixii (1808-1835) French instrument maker who built an early form of alternating current electrical generator based on the principle of electromagnetic induction discovered by Faraday.Edward Samuel Ritchie (1814-1895) American inventor and physicist who made important contributions to science and navigation.Hyde Clarke (1815-1895) English engineer, philologist and author.Floris Nollet (1794-1853) Belgian physicist, engineer and inventor who designed plans for large-scale generators.Werner von Siemens (1816-1892) German electrical engineer, inventor and industrialist.Henry Wilde (1833-1919) English electrical engineer who invented the dynamo-electric machine.William Ladd (1815-1885) English manufacturer of microscopes and other scientific instruments including the Dynamo-Magneto-Electric machine (1867).Antonio Pacinotti (1841-1912) Italian physicist, best known for inventing an improved form of direct-current electrical generator (1860).Zenobe Gramme (1826-1901) Belgian electrical engineer, inventor of the Gramme machine, a type of direct current dynamo capable of generating smoother and much higher voltages than the dynamos known to that point (1871).C. F. Varley (1828-1883) English engineer particularly associated with the development of the electric telegraph and the transatlantic telegraph cable.Charles Wheatstone (1802-1875) English scientist and inventor who made many scientific breakthroughs during the Victorian era.Friedrich von Hefner-Alteneck (1845-1904) German electrical engineer, one of the closest aides of Werner von Siemens.Thomas Edison (1847-1931) American inventor of the electric light bulb among many other items.
