Work
Wollaston became wealthy by developing the first physico-chemical method for processing platinum ore in practical quantities, and in the process of testing the device he discovered the elements palladium (symbol Pd) in 1803 and rhodium (symbol Rh) in 1803.
Anders Gustav Ekeberg discovered tantalum in 1802, however, William Hyde Wollaston declared it was identical with niobium (then known as columbium). Due to Wollaston's influence the existence of columbium was temporarily denied. Later Heinrich Rose proved in 1846 that columbium and tantalum were indeed different elements and he renamed columbium "niobium".
Wollaston also performed important work in electricity. In 1801, he performed an experiment showing that the electricity from friction was identical to that produced by voltaic piles.During the last years of his life he performed electrical experiments that would pave the way to the eventual design of the electric motor. Controversy erupted when Michael Faraday constructed the first working electric motor and hastily published his results without acknowledging Wollaston's previous work. Wollaston, however, saw nothing wrong with Faraday's action. Wollaston also invented a battery that allowed the zinc plates in the battery to be raised out of the acid, so that the zinc wouldn't be dissolved as quickly as it would if it were in the battery all the time.
His optical work was important as well, where he is remembered for his observations of dark Fraunhofer lines in the solar spectrum (1802), which eventually led to the discovery of the elements in the Sun. He invented the camera lucida (1807), the reflecting goniometer (1809), and the Wollaston prism. He also developed the first lens specifically for camera lens called Wollaston's meniscus lens, or just meniscus lens, in 1812. The lens was designed to improve the image projected by the camera obscura. By changing the shape of the lens, Wollaston was able to project a flatter image, eliminating much of the distortion that was a problem with many of that day's biconvex lenses.
Wollaston used his Bakerian lecture in 1805, On the Force of Percussion, to defend Gottfried Leibniz's principle of vis viva, an early formulation of the conservation of energy. Wollaston was too ill to deliver his final Bakerian in 1828 and dictated it to Henry Warburton who read it on 20 November.
Wollaston's attempt to demonstrate the presence of glucose in the blood serum of diabetics was unsuccessful due to the limited means of detection available to him. His 1811 paper "On the non-existence of sugar in the blood of persons labouring under diabetes mellitus" concluded that sugar must travel via lymphatic channels from the stomach directly to the kidneys, without entering the bloodstream. Wollaston supported this theory by referring to the thesis of a young medical student at Edinburgh, Charles Darwin (1758-1778), "Experiments establishing a criterion between mucaginous and purulent matter. And an account of the retrograde motions of the absorbent vessels of animal bodies in some diseases." This Charles Darwin was the eldest son of Erasmus Darwin and not his more famous nephew, Charles Robert Darwin.
Wollaston also served on a royal commission that opposed adoption of the metric system (1819), and one that created the imperial gallon.

Famous quotes containing the word work:
“To see distinctly the machinery—the wheels and pinions—of any work of Art is, unquestionably, of itself, a pleasure, but one which we are able to enjoy only just in proportion as we do not enjoy the legitimate effect designed by the artist.”
—Edgar Allan Poe (1809–1849)
“The press is no substitute for institutions. It is like the beam of a searchlight that moves restlessly about, bringing one episode and then another out of darkness into vision. Men cannot do the work of the world by this light alone. They cannot govern society by episodes, incidents, and eruptions. It is only when they work by a steady light of their own, that the press, when it is turned upon them, reveals a situation intelligible enough for a popular decision.”
—Walter Lippmann (1889–1974)
“Men should not labor foolishly like brutes, but the brain and the body should always, or as much as possible, work and rest together, and then the work will be of such a kind that when the body is hungry the brain will be hungry also, and the same food will suffice for both; otherwise the food which repairs the waste energy of the overwrought body will oppress the sedentary brain, and the degenerate scholar will come to esteem all food vulgar, and all getting a living drudgery.”
—Henry David Thoreau (1817–1862)
