Jean Louis Rodolphe Agassiz has been called the "Father of Glaciology" and the "First Naturalist." Swiss scientist Louis Agassiz was one of the most influential researchers of the 19th century, promoting the Ice Age and boosting science in the United States. But the most persuasive argument for ice ages came in 1837, when Swiss-American geologist Louis Agassiz (1807-1873) gave his now-famous speech on past widespread ice age conditions. Louis Agassiz - Louis Agassiz - Activities in the United States: In 1846 Agassiz visited the United States for the general purpose of studying natural history and geology there but more specifically to give a course of lectures at the Lowell Institute in Boston. Annals of Science, v.24 (2) p.131 – 146 . With the aim of becoming a doctor, he studied from 1824 at the universities of Zurich, Heidelberg and Munich, but educated himself also in nature sciences and botany. For the next 5 years, Agassiz traveled to glacier areas observing their structures and possible movements. – Louis Agassiz, Methods of Study in Natural History (1863), ch. Glacial theory itself was developed in the early 1800s by Jean de Charpentier and other natural scientists. The Ice Age The year 1937 brought some bold hypotheses to the table regarding a possible hypothermal event in the Earth’s past. The origins of ice age theory began hundreds of years ago, when Europeans noted that glaciers in the Alps had shrunk, but its popularization is credited to 19th century Swiss geologist Louis Agassiz. Louis Agassiz. Louis Agassiz, in full Jean Louis Rodolphe Agassiz, (born May 28, 1807, Motier, Switzerland—died December 14, 1873, Cambridge, Massachusetts, U.S.), Swiss-born American naturalist, geologist, and teacher who made revolutionary contributions to the study of natural science with landmark work on glacier activity and extinct fishes.He achieved lasting fame through his … The common explanatory approach was volcanic processes. It was assumed that the erratic blocks in the foothills of the Alps had been carried by large floods from the Alpine peaks to the foothills. The vacation of 1836 was spent by Agassiz and his wife in the little village of Bex, where he met Jean de Charpentier and Ignaz Venetz. The solution to the ice age mystery originated when the National Science Foundation organized the CLIMAP project to study changes in the earth's climate over the past 700,000 years. Many people dislike the philosophy of Louis Agassiz for one reason or another. Proponents of this school of thought believed that new life spontaneously came into existence in the periods after catastrophic events. Born in Switzerland in 1807, Agassiz was the son of a minister. One of the goals was to produce a map of the earth during the last ice age. The ice sheets were not as large as he had thought, the ice age did not arrive as suddenly as he had proposed, and in fact there were several ice ages in succession, not just one giant one. Agassiz was educated and spent his early career in Western Europe (Irmscher, 2013, p. 41-84). Goethe, Charpentier, and Schimper in particular were instrumental in understanding that erratics were moved by glaciers. Their recently-announced glacial theories had startled the scientific world, and Agassiz returned to Neuchâtel as an enthusiastic convert. Louis Agassiz visited the researcher during his scientific journey to the Black Forest and was finally convinced by Schimper’s ideas. Your email address will not be published. A few years after Louis Agassiz’ passing, many scientists were finally convinced by the ice age theory and it slowly reached everyone across Europe, an achievement which Louis Agassiz is mostly remembered for today. In 1848, Agassiz assumed a professorship at Harvard University where his rare gifts as teacher, public speaker, and man of letters earned him the respect of … Evolutionists do not like it that he rejected Darwin’s theory of evolution. He first earned a doctorate in philosophy, followed by a medical degree, both at G… by fat vox. Davies, G.L. Glacial theory itself was developed in the early 1800s by Jean de Charpentier and other natural scientists. In 1832 he became professor of natural history at the University of Neuchatel. In Scandinavia in 1824, Jens Esmark had come to the conclusion that glaciers were at one time more massive in scale. After an invitation from J. Only a few years later,JosephAdhe´marproposedanexplanationofthe existence of ice ages based on the precession of the equinoxes. After Johann Baptist von Spix, who joined his travel, passed away, Agassiz was asked to complete the researcher’s studies which he gratefully did. During the winter of 1836/37, Agassiz and Schimper developed the theory of a sequence of glaciations. In America, he proposed something new: polygeny, or separate creations of different races, closely tied to geography. We now know that ice sheets advance and retreat, altering landscape and climate as they do so. The lectures were followed by another series in Charleston and, later, by both popular and technical lectures in various cities. Louis Agassiz is ... and proposed the theory of continental glaciation, or ice ages. Heralded for helping to shape our understanding of glacial activity and systematics, the study of scientific classification and relationships, he was later ousted for his staunch and unfavorable beliefs regarding evolution and race. In 1842–1846 Agassiz issued his Nomenclator Zoologicus, a classified list, with references, of all names employed in zoology for genera and groups — a work of great labour and research. Finnegan, D.A. Alongside Louis Agassiz, he initiated modern theories on ice ages and climate cycles. Louis Agassiz�s Theory The alternative to Georges Cuvier �s concept, that of severe and sudden cooling, found enormous amplification in the rapidly emerging theory of the ice age, and was promulgated by Louis Agassiz, a young Swiss naturalist who started his career as Cuvier's assistant. 4, p. 42. Remarkably, the very existence of an Ice Age was only first conceived just over 150 years ago when Louis Agassiz first published his theory [002][003]. Agassiz was Swiss, and so he knew glaciers well. Today, the concept of thick ice sheets covering large portions of the globe is a familiar one. A detailed scientific case for ancient glaciation was first synthesized in detail by Jean de Charpentier in the early 1830s, and the great geologist Louis Agassiz became an early convert. Louis Agassiz (1807-1873) was a Swiss-born natural scientist, a professor of zoology and geology in the predecessor of the Harvard School of Engineering and Applied Sciences, and a prominent supporter of racial segregation and white supremacy. He observed many kinds of glacial features, from erratics to moraines, and the many existing features which he eventually presented to the scientific community. Many who held this theory in high regard also believed in a great biblical flood. In 1787 Bernhard Friedrich Kuhn had already suspected glacier activity as the cause and the Scottish geologist James Hutton had come to a similar conclusion. He is the major figure in the development of Ice Age theory. Louis Agassiz was born the son of a Protestant pastor in Vully-le-Haut (today: Haut-Vully) in the district of Môtier, Switzerland. In 1837, Agassiz proposed that the Earth had been subjected to a past ice age. Perhaps the most famous scientist you've never heard of, Louis Agassiz remains one of the most important figures in scientific history. The idea of Continental Glaciation came from Louis Agassiz in 1840. ... Never before had a researcher gathered such extensive and detailed field data to support a new theory. He presented the theory to the Helvetic Societythat ancient glaciers flowed outward from the Alps, and even larger glaciers had covered the plains and mountains of Europ… However, after decades of attempting to convince his fellow researchers and several publications, more and more scientists began to focus on his subject as well. Required fields are marked *, The SciHi Blog is made with enthusiasm by. Supplemented by his own observations, Agassiz came to accept de Charpentier’s theories on alpine glaciers and eventually to propose his own hypotheses. Charpentier first advanced a reasonable scientific explanation of a recent ice age to explain many of the phenomena fou… On May 28, 1807, Swiss paleontologist, glaciologist, and geologist Jean Louis Rodolphe Agassiz was born, who is considered a prominent innovator in the study of the Earth‘s natural history. Yet 200 years after his birth his legacy is almost invisible, tainted by his opposition to Darwinism and his publicly stated racism. They mainly drew upon the preceding works of Venetz, de Charpentier and on their own fieldwork. Agassiz’ hypothesis says that much of the continent of North America was covered by glacial ice that was 2 miles thick and which extended over much of the midwest. They began working on the topic together and Agassiz presented their results on the ice age theory in Switzerland in 1837 dramatically. His engagement for the Lowell Institute lectures precipitated the establishment of the Lawrence Scientific School at Harvard University in 1847 with him as its head. Louis Agassiz, the Ice Age Scientist. While being occupied as professor in Neuchâtel, Louis Agassiz proceeded his research on fish and fossils at the Swiss canton of Glasrus, which depicted the foundation for his later works that made him internationally famous. He attributed the formation of fjords and other such features to glaciers. Louis Agassiz only became involved in the study closer to the middle of the century and thus there were already many prevailing ideas on the nature of alpine glaciers. This skepticism was mostly due to the schism between the differing schools of thought on the past development of Earth’s history in the scientific community at the time. This book tells the exciting story of the ice ages--what they were like, why they occurred, and when the next one is due. Louis Agassiz was born the son of a Protestant pastor in Vully-le-Haut (today: Haut-Vully) in the district of Môtier, Switzerland. astronomical theory of paleoclimate was probably Louis Agassiz’s lecture about his theory of a Great Ice Age at a meeting of the Swiss Society of Natural Sciences, held in Neuchaˆtel in 1837. The work of Jens Esmark is often cited as the the beginning of glacial studies. The 3,946 m high Agassizhorn in the Bernese Alps bears his name in honour of Louis Agassiz. Agassiz appears to have been already familiar with Bernhardi's paper at that time. Several scientists already thought of glacier-activities but had difficulties to prove their ideas. One of his research areas was Maine. In further publications, he explained his new and improved studies. One of the greatest contributors to the science of water, he discovered evidence of a time when the frozen state of water changed Earth's landscape: the Ice Age. In the 1830’s Karl Friedrich Schimper mentioned his theories on a possible ice age and therefore a solution to the boulder problem. How The Scotsman broke the story of the Ice Age ... in 1840 to follow geologists William Buckland and Louis Agassiz as they visited the ... with Buckland to find evidence to back up his theory. He proposed that nearly all of northern Europe and Britain had once been covered by ice, and he subsequently found evidence for his theory in New England. First brought up at home, he spent four years at a secondary school in Biel/Bienne and then studied in Lausanne. LOUIS AGASSIZ, THE GREAT DELUGE, AND EARLY MAINE GEOLOGY DAVID C. SMITH AND HAROLD W. BORNS, JR. * ABSTRACT - Louis Agassiz (1807-1873), in addition to his work on paleoichthyology, had a substantial impact on geological thinking. However, their theses met with just as little acceptance as those of the natural scientist Albrecht Reinhard Bernhardi (1797-1849), who had already argued in an article in 1832 that an ice cap had once extended over Europe, reaching as far as Central Germany. Several publications followed the trip and Agassiz’ reputation across the continent grew. His later book, Système glaciare (1847), presented further evidence for this theory, gathered all over Europe. Agassiz promoted the theory of a catastrophic “ice age” when glaciers covered the early topography and life forms. During his tenure at Harvard, he was, among many other things, an early student of the effect of the last Ice Age on North America. His important researches on fossil fishes were published 1833-44. This school of though also holds that life had developed slowly through evolution and that catastrophes had not taken place or had little impact. © 2021 The Life and Work of Louis Agassiz. “The time has come when scientific truth must cease to be the property of the few, when it must be woven into the common life of the world.” Then Louis Agassiz discovered proof that all Europe had once been covered by crushing glaciers.

Humans, he maintained, included not just different races, but wholly different species, and … Catastrophism – This was the idea that the history of the Earth was formed by great catastrophes that shaped the landscape of the Earth and caused many great extinction events. Unfortunately, their theories were not immediately accepted throughout the scientific community and beyond. In the 1820’s, Agassiz undertook a research journey to Brasil to study fish, which depicted a turning point in his career. By the 1830s, de Charpentier had begun to dedicate himself to glacial studies. A. Lowell, at the Lowell Institute in Boston, Massachusetts, to the U.S., Agassiz decided to settle there. Earth sciences - Earth sciences - William Smith and faunal succession: In 1683 the zoologist Martin Lister proposed to the Royal Society that a new sort of map be drawn showing the areal distribution of the different kinds of British “soiles” (vegetable soils and underlying bedrock). Louis Agassiz is famous for his pioneering of the ice age theory External link, as well as his work in palaeontology and ichthyology External … Louis Agassiz. It took another century before it was fully realised that some of the consequences of the melting of the glaciers at the end of each Ice Age, would have been the flooding of continental shelves and the breaching of low-lying land bridges. Uniformitarianism – This was the idea that the features of the Earth were formed by rather slow “uniform” processes that are still in operation, such as erosion, sedimentation, lithification, volcanism, etc. Louis Agassiz then began working together with William Buckland, finding out how Scottland, England and Wales were formed by glaciers, which they also published. Louis Agassiz's concept of a "Great Ice Age" had to be modified in a number of ways. This knowledge, however, is relatively recent, the result of a great deal of geological deduction on the part of the Swiss scientists Johann von Charpentier (1786-1855) and Jean Louis Agassiz (1807-1873). Harvard appointed him professor of zoology and geology, and he founded the Museum of Comparative Zoology there in 1859 serving as the museum’s first director until his death in 1873. While his work was initially met with skepticism, it laid the foundations for Agassiz to begin his work in the future field of glaciology. He described the movements of glaciers and their historical importance to the Alpine area, as well as clarified how certain areas were once completely covered in ice. Scientists examined cores of sediment from the Indian Ocean bed and deciphered a continuous history for the past 500,000 years. This video has been created by Nicholas Fleming using Vegas Pro 14 video editing software for the EDSC102 Assessment 1: Digital Resource. In Europe, Agassiz had popularized the theory of the Ice Age. By 1841 Charles Lyell, and even Buckland, had been won over, and over the next 20 years, the theory of ancient periods of extensive ice became generally accepted. In 1831 he went to Paris to study a collection of fossils under the guidance of G. Cuvier. About Louis Agassiz. Louis Agassiz, 1807-73, of Fribourg, Switzerland, was the leading advocate of the Glacial Theory. With the aim of becoming a doctor, he studied from 1824 at the universities of Zurich, Heidelberg and Munich, but educated himself also in nature sciences and botany. 1968 The tour of the British Isles made by Louis Agassiz in 1840. British Journal for the History of Science v.37(1) p.29-52 2004 The work of ice: glacial theory and scientific culture in early Victorian Edinburgh. One of the most skeptic researchers was Charles Lyell, who at first supported Agassiz but later rejected his theories for several years. Louis Agassiz (1807-1873) ... Agassiz became a powerful proponent of the theory that a great Ice Age had once gripped the Earth, and published his ideas in Étude sur les glaciers in 1840. Karl Friedrich Schimper: A German naturalist, botanist, and poet who is best known as the theory of prehistoric hot and cold eras. These two contradictory schools of thought were a contentious issue throughout the 19th century: Because Agassiz was once a student of Cuvier, who had first popularized the theory of catastrophism, it is not surprising that Agassiz was initially resistant to the findings of de Charpentier as glacial processes would follow the ideas of uniformitarianism. To his early mentors belonged Alexander von Humboldt [6] and Georges Cuvier,[9] who motivated the young scientist to keep up his interest in geology, zoology and ichtyology. Other scientists believed that these huge boulders were carried on ice floes from the north to their present sites during floods. First brought up at home, he spent four years at a secondary school in Biel/Bienne and then studied in Lausanne. All Rights Reserved. Firstly, Louis Agassiz did not find many supporters, wherefore he put further work in researching and proving his proposition. For many decades, researchers tried to find out how boulders were transported over quite large distances, especially in the foothills of the Alps. Louis Agassiz only became involved in the study closer to the middle of the century and thus there were already many prevailing ideas on the nature of alpine glaciers.
