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.

Born in Leighlinbridge, County Carlow, his early education has been likened to the “hedge school” variety, but the expert tutelage of his teacher, John Conwill, ensured he had a solid foundations in mathematics, English composition, drawing and surveying.

The Form and Function of Scientific Discoveries Kenneth L. Caneva Dibner Library Lecture, Smithsonian Institution Libraries, November 16, 2000 FOREWORD T he Dibner Library Lectures contribute immeasurably to the Smithsonian Libraries' efforts to acquaint the larger public with the valuable materials in the Dibner Library of the History of Science and Technology, and how they are used by scholars. The creative research done by these lecturers and all users of the Dibner Library speak clearly and unmistakably to the continuing usefulness of the volumes Bern Dibner collected and donated to the nation in his 1976 gift to the Smithsonian. This is the tenth lecture in the Dibner Library Lecture Series, supported by The Dibner Fund, and the second to be published. Kenneth L. Caneva delivered this lecture on "The Form and Function of Scientific Discoveries" in November 2000 and prepared it for the present publication with notes and bibliography. We first met Professor Caneva in 1995 when he was selected to be a Smithsonian Libraries Dibner Library Resident Scholar in the early years of that program. Caneva is one of twenty-five scholars who have benefited from this program also generously supported by The Dibner Fund since 1992. The cover image is a well known illustration of science represented as a ship, boldly sailing beyond the Pillars of Hercules, the emblematic limits of the old world. Appearing on the title page of Francis Bacon's Novum Organum (1620), the image epitomizes the spirit of scientific inquiry that forms the basis of Professor Caneva's observations about the experiments and discoveries of Hans Christian Ørsted, Johann Wilhelm Ritter, and Thomas Johann Seebeck, the subjects of his lecture. Bacon's eminence as a philosopher of science was recognized by Bern Dibner, the creator of the Dibner Library of the History of Science and Technology, who included Bacon in his galaxy of 200 pioneers in the history of science and technology, now celebrated as the "Heralds of Science."

Visit the Molecular Expressions Website Galleria Photo Gallery ... Home John Tyndall From a humble background, John Tyndall rose to great heights, becoming one of the most eminent men of science during his period. The self-made man was a powerful lecturer and an influential writer who published on topics ranging from molecular physics and magnetism to mountaineering, literature, religion, and the motion of glaciers. In optics, he is most famous for his discovery of the phenomenon that came to be known as the Tyndall effect Faraday as a Discoverer (1868). Tyndall was also acquainted with the English biologist Thomas H. Huxley, a good friend with whom he coauthored a treatise on glaciers after the pair went on a famous expedition to Switzerland in 1856. Throughout the 1860s, much of Tyndall’s time was spent studying the capacity of various gases and vapors to transmit and absorb radiant heat. In the course of these investigations, he built the first ratio spectrophotometer, an instrument that facilitates the measurement of absorption, and made numerous discoveries. For example, finding that water vapor, carbon dioxide, and ozone are the best absorbers of heat radiation, Tyndall determined that the substances are extremely important in maintaining the surface temperature of the Earth and that fluctuations in their levels in the atmosphere could lead to climate change. He also correctly attributed the formation of dew and frost to heat loss related to radiative processes and argued that London was a “heat island” that was warmer than neighboring areas. These and other findings related to his work on radiant heat were included in

Tyndall was seized by the mountains, and he became one of the most intrepid and resolute of explorers (among other feats of climbing, he was the first to ascend the Weissborn [1861]). He and his wife Louisa (daughter of Lord Claud Hamilton) maintained a cottage on Bel Alp above the Rhone valley. Tyndall's observations on glacier motion brought him into acute conflict with other scientists, though it was he who identified the essential principles and causes of glacier motion. John Tyndall was born in Ireland in poor circumstances. He was a remarkable self-made man of science. "With Darwin and Huxley his name is inseparably connected with the battle which began in the middle of the 19th century for making the new standpoint of modern science part of the accepted philosophy in general life.

This collection of (first?) American editions is an outgrowth of his enormously successful lecture tour of America (1872-3). That trip earned him many thousands of dollars, but he would touch none of it. He placed it instead in the hands of trustees, and directed that it be used for the advancement of American science.

Tyndall, John Irish physicist who 1869 studied the scattering of light by invisibly small suspended particles in colloids. Known as the Tyndall effect, it was first observed with colloidal solutions, in which a beam of light is made visible when it is scattered by minute colloidal particles (whereas a pure solvent does not scatter light). Similar scattering of blue wavelengths of sunlight by particles in the atmosphere makes the sky look blue (beyond the atmosphere, the sky is black). Tyndall was born in County Carlow and studied at Marburg, Germany. He became professor at the Royal Institution 1853 and was also professor at the Royal School of Mines 1859-68. As superintendent of the Royal Institution from 1867, he did much to popularize science in Britain and also in the USA, where he toured from 1872 to 1873. Having established that there are dust particles suspended in the air, Tyndall was able to show that the air contains living microorganisms. This confirmed the work of French chemist Louis Pasteur that rejected the spontaneous generation of life, and it also inspired Tyndall to develop methods of sterilizing by heat treatment. Tyndall also carried out experimental work on the absorption and transmission of heat by gases, especially water vapour and atmospheric gases, which was important in the development of meteorology.

39. John Tyndall John Tyndall {18201893} was a man of science—draftsman, surveyor, physicsprofessor, mathematician, geologist, atmospheric scientist, public lecturer, http://www.tqnyc.org/NYC030244/john_tyndall.htm

In January 1859, Tyndall began studying the radiative properties of various gases. Part of his experimentation included the construction of the first ratio spectrophotometer, which he used to measure the absorptive powers of gases such as water vapor, "carbonic acid" (now known as carbon dioxide), ozone, and hydrocarbons. Among his most important discoveries were the vast differences in the abilities of "perfectly colorless and invisible gases and vapors" to absorb and transmit radiant heat. He noted that oxygen, nitrogen, and hydrogen are almost transparent to radiant heat while other gases are quite opaque. Tyndall's experiments also showed that molecules of water vapor, carbon dioxide, and ozone are the best absorbers of heat radiation, and that even in small quantities, these gases absorb much more strongly than the atmosphere itself. He concluded that among the constituents of the atmosphere, water vapor is the strongest absorber of radiant heat and is therefore the most important gas controlling Earth's surface temperature. He said, without water vapor, the Earth's surface would be "held fast in the iron grip of frost." He later speculated on how fluctuations in water vapor and carbon dioxide could be related to climate change. The above graphs show the percentage of radiation that gases found in the Earth's atmosphere absorb. Methane (CH
