Tyndall, John (1820-1893) One of the most influential mountaineers of the Victorian age. First visited the Alps in 1856 with T.H. Huxley to make scientific observations. Made his third ascent of Mont Blanc in 1859 and spent 20 hours on the summit carrying out scientific work. His The Glaciers of the Alps (1860) produced one of the great controversies of the time. His chief opponent was Forbes. In 1860 reached 13,000 feet on the Matterhorn, the highest point then gained, and during the following year made the first ascent of the Weisshorn. Resigned from the Alpine Club in 1862 after a famous after-dinner speech by Leslie Stephen which caricatured scientific observation by mountaineers. Elected Honorary Member in 1887.

John Tyndall (1820 - 1893) John Tyndall was born into a small landowning family in Country Carlow in Ireland. Although relatively poor, his father ensured his son received a good elementary education. A gifted child, he would walk home with his tutor, working on Euclid's geometrical problems in the snow. He began work as a draughtsman with the Ordnance Survey in 1839, and then travelled to the University at Marburg in Germany to study chemistry and physics. He received his PhD in two years, published his first paper a year later and became a fellow of the Royal Society a year after that. In 1853 he started working alongside Michael Faraday at the Royal Institution where he continued his research, succeeding him there as superintendent in 1867. Over the previous decade he had been researching heat transfer in gases and vapours, with interesting results. Taking some very pure, highly filtered water, he saw that a visible beam of light completely disappeared when it went through the pure water. He repeated the experiment with filtered air and achieved the same result. He had discovered that light only became visible after bouncing off air particles. He experimented further by changing the size of the particles and found that different sized particles scattered light in different ways. In the 1660s Newton had demonstrated that visible light coming from the sun was made up of different colours. Tyndall discovered that light at the blue and violet end of the spectrum was scattered by minute particles and light at the red end was scattered by bigger particles. Because the atmosphere contains smaller particles, scattering the blue light, the sky appears blue. He went to show that 'optically pure' air contains no bugs or germs by preparing various concoctions of dead fish and meat and then letting them putrefy. The same concoctions in pure air did not do this.

The Encyclopedia of Astrobiology, Astronomy, and Spaceflight about main latest news news archive ... Z Tyndall, John (1820-1893) Irish physicist who championed the now-accepted notion that there is no fundamental difference between animate and inanimate matter, and that the origin of life was chemical: . . . the matter of the animal body is that of inorganic nature. There is no substance in the animal tissues which is not primarily derived from the rocks, the water and the air. . . . a perfect reversal of this process of reduction would carry us from the inorganic to the organic, and such a reversal is at least conceivable. Carrying on from where Spallanzini de la Tour , and Pasteur had left off, Tyndall also finally disposed of the old idea of spontaneous generation by answering the last objection raised by supporters of that view. It had been observed that microbes sometimes began growing in infusions, such as those of hay, even after the latter had been boiled. Tyndall showed that the reason for this was that the hay contained spores which can survive even after long exposure to high temperature.

John Tyndall (1820-1893) John van Wyhe Herbert Spencer In 1874 Tyndall gave his famous Belfast address before the annual meeting of the British Association for the Advancement of Science. It was one of the most prestigious places from which to pronounce on what men of science should be doing. Tyndall famously used his address to argue for the superior authority of science over religious or non-rationalist explanations. By the time of this address the Association had largely been taken over by the young guard, men like T.H. Huxley and Tyndall. Nevertheless, Tyndall's bold statement for rationalism and natural law was made in Belfast, a stronghold of religious belief then as now and so it was taken as an aggressive attack on religion. The address was popularly believed to advocate materialism as the true philosophy of science. It remains a powerful call for rationalism, consistency, and scepticism. Further reading Tyndall.

16. John Tyndall (1820-1893) World Acclaimed Scientist Of Leighlinbridge, Co. Carlow John Tyndall was born in Leighlinbridge, Co. Carlow on 2nd August 1820. Itwas a pay school, a luxury that John Tyndall senior could ill afford. http://www.rootsweb.com/~irlcar2/John_Tyndall.htm

A short Biography of World Acclaimed Scientist John Tyndall was born in Leighlinbridge, Co. Carlow on 2nd August 1820. During the course of his life, this very intelligent poet-scientist was to invent practical items such as a safe miners' lamp, a powerful lighthouse beacon and the first practical gas mask therefore being responsible for saving the lives of many thousands of miners, sailors and common labourers. In France, Pasteuration is called Tyndallization, for it was John Tyndall who apparently first discovered the process of killing bacteria in milk, Louis Pasteur merely passed along Tyndall's discovery to mankind. Per article in "Ireland of the Welcomes," Tyndall could be called a brilliant but "invisible scientist" whose theories and accomplishments were often attributed to others. John Tyndall also described the action of the fungus penicillin on bacteria over a century before Sir Alexander Fleming re-discovered the antibiotic. Tyndall was also a master mountaineer, and was the first person to climb several peaks in the Alps. He reached to within a few hundred feet of the top of the famed Matterhorn the year before Whymper succeeded in the difficult climb. Tyndall joined the Ordnance Survey as a Civil Servant on 01 April 1839. For a short time he surveyed in Co Carlow close to his home, but in 1840 he was transferred to Youghal in Co. Cork. In 1842 he was transferred by the Ordnance Survey to Preston in England. He never returned to Ireland expect for short visits home. In Preston he joined the Chartist labour movement led by immigrants from Ireland. His articles in the "Liverpool Mercury" were outspoken and exposed the injustices to the lower working classes, Irish and English alike. Since the Civil Service could ill afford to be politicised by his strong position concerning labour he was fired and returned to Carlow to rethink his future.

The population of the county almost halved in forty years. The Great Famine period played a very big part in this with emigration also to blame.
