Woodburytype photographic oval portrait, [(11.2 x 8.7cm) or (4 3/8 x 3 3/8 inches)] mounted centrally on original thin card leaf with title. Fine clean condition for the portrait, ideal for framing. This Woodburytype photo was extracted from a collection of portraits, photographed from life by Lock and Whitfield, between 1876 and 1883. Many images have been provided above in order for you to examine the condition of photograph. [The Woodburytype process was invented by Walter Bentley Woodbury (British, 1834–1885) / Joseph Wilson Swan (British, 1828–1914). Patented 1864, working details published 1865. The Woodburytype process was one of the first successful photomechanical processes fully able to reproduce the delicate halftones of photographs. It was often considered the most perfect, most beautiful photomechanical process and inspired a number of books, magazines, and special edition printings between 1864 and 1910. When attempts were made to adopt Woodburytype to rotary printing, the process could not compete with the quickly developing collotype and halftone photomechanical processes that almost completely replaced Woodburytype by the end of the nineteenth century.] Wikipedia. Sir William Robert Grove, (11 July 1811 – 1 August 1896) was a Welsh judge and physical scientist. He anticipated the general theory of the conservation of energy, and was a pioneer of fuel cell technology. He invented the Grove voltaic cell. n 1839, Grove developed a novel form of electric cell, the Grove cell, which used zinc and platinum electrodes exposed to two acids and separated by a porous ceramic pot. Grove announced the latter development to the Académie des Sciences in Paris in 1839. In 1840 Grove invented one of the first incandescent electric lights, which was later perfected by Thomas Edison.Later that year he gave another account of his development at the British Association for the Advancement of Science meeting in Birmingham, where it aroused the interest of Michael Faraday. On Faraday's invitation Grove presented his discoveries at the prestigious Royal Institution Friday Discourse on 13 March 1840. Grove's presentation made his reputation, and he was soon proposed for Fellowship of the Royal Society by such distinguished men as William Thomas Brande, William Snow Harris and Charles Wheatstone. Grove also attracted the attention of John Peter Gassiot, a relationship that resulted in Grove's becoming the first professor of experimental philosophy at the London Institution in 1841. Grove's inaugural lecture in 1842 was the first announcement of what Grove called the correlation of physical forces, in modern terms, the conservation of energy. In 1842, Grove developed the first fuel cell (which he called the gas voltaic battery), which produced electrical energy by combining hydrogen and oxygen, and described it using his correlation theory. In developing the cell and showing that steam could be disassociated into oxygen and hydrogen, and the process reversed, he was the first person to demonstrate the thermal dissociation of molecules into their constituent atoms. The first demonstration of this effect, he gave privately to Faraday, Gassiot and Edward William Brayley, his scientific editor. His work also led him to early insights into the nature of ionisation. For observations made in Ref., Grove is credited for the discovery of sputtering. In the 1840s Grove also collaborated with Gassiot at the London Institution on photography and the Daguerreotype and calotype processes. Inspired by his legal practice, he presciently observed: It would be vain to attempt specifically to predict what may be the effect of Photography on future generations. A Process by which the most transient actions are rendered permanent, by which facts write their own annals in a language that can never be obsolete, forming documents which prove themselves, — must interweave itself not only with science but with history and legislature. — London Institution, 19 January 1842 In 1852 he discovered striae, dark bands that occur in electrical breakdown, and investigated their character, presenting his work in an 1858 Bakerian lecture. In 1846, Grove published On The Correlation of Physical Forces in which he anticipated the general theory of the conservation of energy that was more famously put forward in Hermann von Helmholtz' Über die Erhaltung der Kraft (On the Conservation of Force) published the following year. His 1846 Bakerian lecture relied heavily on his theory. James Prescott Joule had been inspired to his investigations into the mechanical equivalent of heat by comparing the mass of coal consumed in a steam engine with the mass of zinc consumed in a Grove battery in performing a common quantity of mechanical work. Grove was certainly familiar with William Thomson's theoretical analysis of Joule's experimental results and Thomson's immature suggestions of conservation of energy. Thomson's public champion, Peter Guthrie Tait was initially a supporter of Grove's ideas but later dismissed them with some coolness. Though Groves's ideas were forerunners of the theory of the conservation of energy, they were qualitative, unlike the quantitative investigations of Joule or Julius Robert von Mayer. His ideas also shaded into broader speculation, such as the nature of Olbers's paradox, which he may have discovered for himself rather than through a direct knowledge. ... it is difficult to understand why we get so little light at night from the stellar universe, without assuming that some light is lost in its progress through space – not lost absolutely, for that would be an annihilation of force – but converted into some other mode of motion. — On the Correlation of Physical Forces (1874) Grove also speculated that other forms of energy were yet to be discovered "as far certain as certain can be of any future event." The probability is that, if not all, the greater number of physical phenomena are, in one sense correlative, and that, without a duality of conception, the mind cannot form an idea of them: thus motion cannot be perceived or probably imagined without parallax or relative change of position ... in all physical phenomena, the effects produced by motion are all in proportion to the relative motion. ... The question of whether there can be absolute motion, or indeed any absolute isolated force, is purely themetaphysical question of idealism or realism. — On the Correlation of Physical Forces (1874) From 1846 Grove started to reduce his scientific work in favour of his professional practice at the bar, his young family providing the financial motivation; and in 1853 became a QC. The bar provided him with the opportunity to combine his legal and scientific knowledge, in particular in patent law and in the unsuccessful defence of poisoner William Palmer in 1856. He was especially involved in the photography patent cases of Beard v. Egerton (1845–1849), on behalf of Egerton, and of Talbot v. Laroche (1854). In the latter case Grove appeared for William Fox Talbot in his unsuccessful attempt to assert his calotype patent. Grove served on a Royal Commission on patent law and on the Metropolitan Commission of Sewers. In 1871 he was made judge of the Court of Common Pleas, and was appointed to the Queen's Bench in 1880.He was to have presided at the Cornwall and Devon winter assizes of 1884, which would have entailed him trying the notorious survival cannibalism case of R v. Dudley and Stephens. However, at the last minute he was substituted by Baron Huddleston, possibly because Huddleston was seen as more reliable in ensuring the guilty verdict that the judiciary required. Grove did sit as one of five judges on the final determination of the case in the Divisional Court of the Queen's Bench. Grove was a careful, painstaking and accurate judge, courageous and not afraid to assert an independent judicial opinion. However, he was fallible in patent cases, where he was prone to become over-interested in the technology in question and to be distracted by questioning the litigants as to potential improvements in their devices, even going so far as to suggest his own innovations. He retired from the bench in 1887.
