He is best known, however, for discovering the Tyndall effect , in which a beam of light becomes visible when passing through a colloid Tyndall popularized the molecular vibration theory of heat which had been developed by Maxwell in Heat as a Mode of Motion (1863). He also defended Julius Mayer's claim to be the originator of the Law of energy conservation because of his priority in discovering the mechanical equivalent of heat

The Encyclopedia of Astrobiology, Astronomy, and Spaceflight FRONT PAGE NEWS ARCHIVE NEWSLETTER ... Z this site WWW 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.

4. John Tyndall (1820-1893) World Acclaimed Scientist Of Leighlinbridge, Co. Carlow John Tyndall was born in Leighlinbridge, Co. Carlow on 2nd August 1820 for it was John Tyndall who apparently first Pasteur merely passed along Tyndall's discovery to mankind 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.

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.

JOHN TYNDALL TYNDALL, JOHN (1820-1893), British natural philosopher, was born in Co. Carlow, Ireland, on the 2nd of August 1820, his father being the son of a small landowner in poor circumstances, but a man of more than ordinary ability, With Darwin and Huxley his name is inseparably connected with the battle which began in the middle of the ipth century for making the new standpoint of modem science part of the accepted philosophy in general life. For many years, indeed, he came to represent to ordinary Englishmen the typical or ideal professor of physics. His strong, picturesque mode of seizing and expressing things gave him an immense living influence both in speech and writing, and disseminated a popular knowledge of physical science such as had not previously existed. But besides being a true educator, and perhaps the greatest popular teacher of natural philosophy in his generation, he was an earnest and original observer and explorer of nature. Tyndall was to a large extent a self-made man; he had no early advantages, but with indomitable earnestness devoted himself to study, to which he was stimulated by the writings of Carlyle. He passed from a national school in Co. Carlow to a minor post (1839) in the Irish ordnance survey, thence (1842) to the English survey, attending mechanics' institute lectures at Preston in Lancashire. He then became for a time (1844) a railway engineer, and in 1847 a teacher at Queenwood College, Hants. Thence with much spirit, and in face of many difficulties, he betook himself, with his colleague Edward Frankland, to the university of Marburg (1848-1851), where, by intense application, he obtained his doctorate in two years. His inaugural dissertation was an essay on screw-surfaces.

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.
