Crookes, W. Certain Properties of the Emanations of Radium. [4], Crookes was named president of the British Association for the Advancement of Science in 1898. Their first child, Alice Mary (born 1857, later Mrs. Cowland) remained unmarried for forty years, living with her parents and working as an assistant to her father. He was considered remarkable for his industriousness and for his intellectual qualities. [57][58] Psychologists Leonard Zusne and Warren H. Jones have described Crookes as gullible as he endorsed fraudulent mediums as genuine. These were the subject of his first published papers, in 1851. Crookes did not, however, provide the true explanation of this apparent "attraction and repulsion resulting from radiation". The method of spectral analysis, introduced by Bunsen and Kirchhoff, was received by Crookes with great enthusiasm and to great effect. [11][10], Crookes developed the Crookes tube,[19] investigating cathode rays. [3], Married and living in London, Crookes sought to support his new family through independent work as a photographic chemist. He believed that he had discovered a fourth state of matter, which he called "radiant matter",[25] but his theoretical views on the nature of "radiant matter" were to be superseded. He noted that contrary to popular belief, Hope had been exposed as a fraud on several occasions. For a time, he was interested in spiritualism and became president of the Society for Psychical Research. Save my name, email, and website in this browser for the next time I comment. (16 May 1862) "De l'existenc d'un nouveau mtal, le thallium,", The difference between "Crookes tubes" and ". At about the same time as this important discovery, he observed that when "p-particles", ejected from radio-active substances, impinge upon zinc sulfide, each impact is accompanied by a minute scintillation, an observation which forms the basis of one of the most useful methods in the detection of radioactivity. [55][56], Between 1871 and 1874, Crookes studied the mediums Kate Fox, Florence Cook, and Daniel Dunglas Home.

[1] Since staff at Chester were required to be bachelors, he had to resign his position. [2] Sir William Crookes OM PRS (/krks/; 17 June 1832 4 April 1919) was a British chemist and physicist who attended the Royal College of Chemistry[1], now part of Imperial College London, and worked on spectroscopy.

"[60] Biographer William Hodson Brock wrote that Crookes was "evidently short-sighted, but did not wear spectacles until the 1890s. Two of Crookes' sons became engineers, and two lawyers. There all his later work was done, in what was then "the finest private laboratory in Britain". He received many public and academic honours. One of Crookes' students was the Reverend John Barlow, Secretary of the Royal Institution, who chose to take a course in analytical chemistry. Crookes' samples were made by Whitefriars, London, stained glass makers, and Chance Brothers, Birmingham. Scientists addressing the problem in the first years of the twentieth century included Kristian Birkeland, whose technology helped found Norsk Hydro, and Fritz Haber and Carl Bosch, whose HaberBosch process forms the foundation of today's nitrogen fertilizer industry. The reason, he said, was a dearth of nitrogen fertilizer available from natural sources. Crookes called on chemists to develop new ways of making fertilizer from the enormous stock of nitrogen in the atmosphere (which is roughly 80 percent nitrogen). What limitations this imposed upon his psychic investigations we can only imagine. [3]:8, When Crookes embarked upon original work, it wasn't in organic chemistry, but rather into new compounds of selenium. [63][64][65][66][67], In a series of experiments in London, England at the house of Crookes in February 1875, the medium Anna Eva Fay managed to fool Crookes into believing she had genuine psychic powers. [72] In a review, biographer William Brock wrote that Stein made his "case against Crookes and Home clearly and logically. At various times he edited the Journal of the Photographic Society and the Photographic News. He published numerous papers on spectroscopy and conducted research on a variety of minor subjects. [53][54] [2][3], William Crookes was born in London in 1832, the eldest of eight surviving children (eight others died young) of Joseph Crookes (1792-1889), a wealthy tailor and real estate investor of north-country origin, and his second wife, Mary (ne Scott; 1806-1884). He also suggested that Crookes had conspired with Anna Eva Fay. [29][30][31], After 1880, Crookes lived at 7 Kensington Park Gardens in the fashionable area of Notting Hill. 1660), had been Mayor of Hartlepool, County Durham on three occasions. In his investigations of the conduction of electricity in low pressure gases, he discovered that as the pressure was lowered, the negative electrode (cathode) appeared to emit rays (the so-called "cathode rays", now known to be a stream of free electrons, and used in cathode ray display devices). Cornell University, 1903. His father's shop was about half a mile away. Crookes also invented a 100% ultraviolet blocking sunglass lens. [3][22][23][24], Portrait of Sir William Crookes, O.M., age 79, Sir William Crookes by Sir Leslie Ward, 1902, Crookes investigated the properties of cathode rays, showing that they travel in straight lines, cause fluorescence when they fall on some substances, and that their impact can produce great heat. Through Barlow, Crookes met scientists such as George Gabriel Stokes and Michael Faraday. "[3]:140, After studying the reports of Florence Cook, the science historian Sherrie Lynne Lyons wrote that the alleged spirit "Katie King" was at times Cook herself and at other times an accomplice. [3]:1213 Journal of the Franklin Institute of the State of Pennsylvania, Volume 81. Both Crookes and Lamy isolated the element in 1862. [8] In 1855 he was appointed lecturer in chemistry at the Chester Diocesan Training College. [2][3][10][11][12], His first important discovery was that of the element thallium, made with the help of flame spectroscopy. By 1851, Crookes' interest in photography and optics caused his father to build him a laboratory in the garden at home for his research. After his investigation, he believed that the mediums could produce genuine paranormal phenomena and communicate with spirits. Crookes paid 25 for his first year's tuition and had to provide his own apparatus and some of the more expensive chemicals.

[3], On 16 January 1884, Crookes' father died. [3]:810, Although Crookes revered Hofmann, he did not share his primary interest in organic chemistry. [21] He also devised one of the first instruments for studying nuclear radioactivity, the spinthariscope. He was also helped by his daughter Alice, who was "adept at fractionating rare earth elements" and "no mean interpreter of spectra".

His experiments in chemistry and physics were known for the originality of their design,[3] and he is considered a "superb experimentalist". Combined with his previous income, this ensured that Crookes was very well off. [52], Crookes was possibly influenced by the death of his younger brother Philip in 1867 at 21 from yellow fever contracted while he was on an expedition to lay a telegraph cable from Cuba to Florida. [3][10][11][12][13][14][15], Thallium was also independently discovered by Frenchman Claude Auguste Lamy, who had the advantage of access to large amounts of materials via his brother-in-law, Charles Frdric Kuhlmann. Until then he may have used a monocle or pocket magnifying glass when necessary. Harry Marshall Diemer, Ralph Stuart Cooper.

[3], His daily routine was to manage his commercial affairs in the morning, do further business or go to scientific meetings in the afternoon, eat dinner at 7, work in his library from 8 to 9, and then in the laboratory until after midnight. In addition, William Crookes, who had been asked to examine a sample, presented on the spectra of argon, reported that argon displayed two distinct spectra. [62] Some researchers such as Trevor H. Hall suspected that Crookes had an affair with Cook. [7], Joseph Crookes had had five children with his first wife; two sons from that marriage, Joseph and Alfred, took over the tailoring business, leaving William free to choose his own path. He was a pioneer of vacuum tubes, inventing the Crookes tube which was made in 1875. From his home, Crookes could easily reach the Chemical News offices, the Royal Society, the Chemica Society, and the Athenaeum Club. [74], British chemist and physicist (18321919), William Crookes (18321919) and the Commercialization of Science, William H. Brock, Routledge, 2008; Routledge, pp. He is credited with discovering the element thallium, announced in 1861, with the help of spectroscopy. Benn Brothers., 1902.

Radio-activity induced by the oscillatory discharge, or, The subsequent radio-active emanation from substances exposed to the Tesla oscillatory discharge. [3]:440 In 1890 he was initiated into the Hermetic Order of the Golden Dawn. [48][49][50][51][46], Crookes became interested in spiritualism in the late 1860s, and was most strongly involved around 18741875. Lecture delivered before the British Association for the Advancement of Science, at Sheffield, Friday, 22 August 1879. [37], In 1903, Crookes turned his attention to the newly discovered phenomenon of radioactivity, achieving the separation from uranium of its active transformation product, uranium-X (later established to be protactinium). [5][6] Joseph Crookes's father, William (1734-1814), was also a tailor, and his grandfather, John Crookes (b. Your email address will not be published. William Crookes, On Radiant Matter. William's father, Joseph Crookes, gave the couple a house at 15 Stanley Street, Brompton. In 1867, influenced by Cromwell Fleetwood Varley, Crookes attended a sance to try to get in touch with his brother. 3-4, Crookes, William (30 March 1861) "On the existence of a new element, probably of the sulphur group,", Crookes, William (18 May 1861) "Further remarks on the supposed new metalloid,", Crookes, William (19 June 1862) "Preliminary researches on thallium,", Lamy, A.

[9], In April 1856 Crookes married Ellen, daughter of William Humphrey of Darlington. Crookes was the inventor of the Crookes radiometer but did not discern the true explanation of the phenomenon he detected. Joseph Crookes' estate was left in trust, divided between his three surviving sons, Alfred, William and Frank. His household included a large multigenerational family and a number of servants. Lecture delivered before the Franklin Institute, 17 February 1881. [59], The anthropologist Edward Clodd noted that Crookes had poor eyesight, which may have explained his belief in spiritualist phenomena and quoted William Ramsay as saying that Crookes is "so shortsighted that, despite his unquestioned honesty, he cannot be trusted in what he tells you he has seen. [4] His interests, ranging over pure and applied science, economic and practical problems, and psychic research, made him a well-known personality and earned him a substantial income. [39], In 1913, Crookes[40] created a 100% ultraviolet and 90% infrared blocking lens[41][42][43] made from glass containing cerium,[44] but only lightly tinted. [2][3][11] Crookes wrote a standard treatise on Select Methods in Chemical Analysis in 1871. [45] They were an unintended by-product of Crookes's research to find a lens glass formulation that would protect glass workers from cataracts. [32], On 13 August 1894, John William Strutt, 3rd Baron Rayleigh and William Ramsay announced the detection of a new gas in the atmosphere. He worked with Manuel Johnson at the Radcliffe Observatory in Oxford in 1854, where he adapted the recent innovation of wax paper photography to machines built by Francis Ronalds to continuously record meteorological parameters. Stein concluded that all feats of Hope were conjuring tricks. He named the element thallium, from Greek , thalls, meaning "a green shoot or twig". Eric Deeson notes that Crookes' studies of the occult are related to his scientific work on radiometry in that both involved the detection of previously undiscovered forces. "[71], In 1916, William Hope tricked Crookes with a fake spirit photograph of his wife. [61] Cook was repeatedly exposed as a fraudulent medium but she had been "trained in the arts of the sance" which managed to trick Crookes. In his inaugural address, he outlined in detail a coming catastrophe: The wheat-eating peoples of the world were going to start running out of food in the 1930s. [3], In 1866, Adolf Erik Nordenskild identified a rare mineral from Skrikerum as a selenide of copper, thallium, and silver (Cu7(Tl, Ag)Se4), and named the mineral crookesite in honor of Sir William Crookes. Ellen's mother, Mrs. Humphrey, lived with them for the rest of her life, nearly forty years. I don't wanna play nice I wanna cause problems [problemIf you want 'em I got 'emWhat you want what you want you a problem? On 31 January 1895 they made a full report to the Royal Society on the new gas, argon. "[73], Crookes joined the Society for Psychical Research, becoming its president in the 1890s: he also joined the Theosophical Society and The Ghost Club,[53] of which he was president from 1907 to 1912. He was also the first to describe the spectrum of terrestrial helium, in 1865. As these examples indicate, he was a pioneer in the construction and use of vacuum tubes for the study of physical phenomena. [3] D. Appleton, 1880. Crookes was knighted in 1897. [3] In 1859, he founded the Chemical News, a science magazine which he edited for many years and conducted on much less formal lines than was usual for the journals of scientific societies. Crookes lived with his parents about three miles from the College in Oxford Street. [68] Regarding Crookes and his experiments with mediums, the magician Harry Houdini suggested that Crookes had been deceived. Crookes discovered a previously unknown element with a bright green emission line in its spectrum. [3]:11 [34][35][36] [2] The discovery of argon and of helium led to identification of the noble gases and the reorganization of the periodic system. Landscape format, printed on one side only of a single sheet of white paper.) [3]:35, By 1880 Crookes employed a paid full-time scientific assistant (first Charles Gimingham and after 1883 James Gardiner). Crookes himself suggested a design for a Periodic table in the style of a space lemniscate in 1898. He soon discovered the phenomenon which drives the movement in a Crookes radiometer, in which a set of vanes, each blackened on one side and polished on the other, rotate when exposed to radiant energy. At the end of his second year, Crookes became a junior assistant to August Wilhelm von Hofmann, doing laboratory demonstrations and helping with research and commercial analysis. 87:241; 1903. [3], Crookes was effective in experimentation. His remarks on the coming famine achieved wide distribution in the press and were turned into a popular book. Regarding Crookes, Lyons wrote, "Here was a man with a flawless scientific reputation, who discovered a new element, but could not detect a real live maiden who was masquerading as a ghost". A devoted couple, William and Ellen Crookes had six sons and three daughters. In October 1851, Crookes was promoted to senior assistant, a position he held until 1854. By the late Derek R. Guttery", "Crookes, Sir William (18321919), chemist and science journalist", "Rediscovery of the elements: Thallium, Crookes, and Lamy", "XLVI. Required fields are marked *. [46] Crookes tested more than 300 formulations,[47] each numbered and labelled. It comprised an entire floor of the house and included three interconnected laboratory rooms, for chemistry, physics, and mechanical construction, and a library. [33] Chemical News; Vol. Crookes Glass 246 was the tint recommended for glassworkers. Crookes's findings were published on 30 March 1861. Oliver Lodge revealed there had been obvious signs of double exposure, the picture of Lady Crookes had been copied from a wedding anniversary photograph, but Crookes was a convinced spiritualist and claimed it was genuine evidence for spirit photography. The best-known Crookes tints are A (withdrawn due to its uranium), A1, B, and B2, which absorb all ultraviolet below 350nm while darkening visual light. "[70], In 1897, John Grier Hibben wrote that Crookes' idea of ether waves explaining telepathy was not a scientific hypothesis "he presents no facts to indicate its probability or to save it from being relegated to the sphere of bare conjecture. It remained for Sir J. J. Thomson to expound on the subatomic nature of cathode rays (consisting of streams of negative electrons[27]). [10][16][17][18][12], Crookes was elected a fellow of the Royal Society in 1863.

This was a foundational discovery that eventually changed the whole of chemistry and physics. Chemist & Druggist, Volume 60. Avec ses vtements ondoyants et nacrs . [28], Crookes' attention had been attracted to the vacuum balance in the course of his research into thallium. [26] He believed the rays to consist of streams of particles of ordinary molecular magnitude. By Franklin Institute (Philadelphia, Pa.). [38] Crookes observed the gradual decay of the separated transformation product, and the simultaneous reproduction of a fresh supply in the original uranium. Crookes' daughter Florence died of scarlet fever in the same week. [20] He was, as a consequence, one of the first scientists to investigate what is now called a plasma and identified it as the fourth state of matter in 1879. [3]:474, The physiologist Gordon Stein suspected that Crookes was too ashamed to admit he had been duped by the medium Florence Cook or that he conspired with her for sexual favors. Crookes' life was one of unbroken scientific activity that extended over sixty-seven years. [7] In 1848, at age 16, Crookes entered the Royal College of Chemistry (now the Imperial College chemistry department) to study organic chemistry. Fay later confessed to her fraud and revealed the tricks that she had used. Negatively electrified particles whose mass is only 1/1840 that of a, "William Crookes: Covert Resources and a Mentor, 187181. Between 1864 and 1869, he was also involved with the Quarterly Journal of Science. Crookes was able to purchase the house and build the laboratory because of his income from the National Guano Company and from various patents. At the end of his first year, Crookes won the Ashburton scholarship which covered his second year's tuition. Nevertheless, Crookes's experimental work in this field was the foundation of discoveries which eventually changed the whole of chemistry and physics. Such friends reinforced Crookes' interest in optical physics[3]:13 which was respected by Hofmann. Alexander E. Outerbridge, Jr., A Fourth State of Matter. [69] The physicist Victor Stenger wrote that the experiments were poorly controlled and "his desire to believe blinded him to the chicanery of his psychic subjects. [3], In 1886, Crookes was elected as a member to the American Philosophical Society. In this way, Crookes identified the first known sample of terrestrial helium[33] and established its correspondence to observations of solar helium. The Popular Science Monthly, Volume 16.
