		He made an unsuccessful 1 His father, Nicolas de Saussure (1709-1790), an agriculturist of unusually liberal opinions, resided all his life at his farm of Conches, on the Arve, near Geneva.
		Saussure's geological observations made him a firm believer in the Neptunian theory: he regarded all rocks.

		de Saussure was born in Conches, near Geneva.
		Saussure's geological observations made him a firm believer in the Neptunian theory: he regarded all rocks and minerals as deposited from aqueous solution or suspension, and attached much importance to the study of meteorological conditions.
		De Saussure was honoured by being depicted on the 20 Swiss franc banknote of the sixth issue of Swiss National Bank notes (1979-1995 when replaced by the eighth issue, and the notes were recalled in 2000) (These notes will become valueless on 1 May 2020).

	De Saussure, Nicolas-Théodore - Swiss botanist 1767–1845
		Nicolas de Saussure was an early pioneer in plant physiology.
		De Saussure studied gas and nutrient uptake in plants, using the scientific method of controlled experimentation.
		De Saussure also studied oxygen consumption in germinating seeds and plants grown in the dark, and argued (correctly) that the use of oxygen by plants was similar to that of animals.

		Two different scientists found the Discovery of Photosynthesis: Jean Senebier and Theodore de Saussure.
		Jean Senebier, a French pastor, showed that CO2 was the "fixed" or "injured" air and that plants in photosynthesis took it up.
		Very soon afterwards, Theodore de Saussure showed that the increase in mass of the plant as it grows could not be due only to uptake of CO2, but also to the incorporation of water.

		He learned of Priestley's experiments, and spent a summer near London doing over 500 experiments, and he discovered that light or sunlight to be specific plays an important role in the occurrence of photosynthesis.
		Soon after Jean Senebier (right) working in Geneva noticed that "fixed air" or CO Theodore de Saussure also working in Geneva discovered that water also played a major role in the occurrence of photosynthesis.
		The last piece of the puzzle of photosynthesis water put in by a German surgeon, Julius Robert Mayer (right), who discovered that all plants convert solar energy received through the leaves into chemical energy that the plant needs to survive.

	Florence 2004 - Coral Gardens — The Dolomites
		Those mountains are known around the world today as the Dolomites, but the new name, dating back little more than two hundred years and popular beginning only in the early 1900s, does not have an equally poetic origin.
		In fact, in 1789 Marquis Déodat de Dolomieu took a study trip to southern Tyrol, where along the road from Trento to Bolzano he collected samples of a light-coloured rock similar to limestone, but unlike this latter scarcely if at all reactive when bathed in hydrochloric acid.
		It was chemist Nicolas Théodore de Saussure who analysed those samples and discovered that they were composed of a mineral yet to be clearly identified, a calcium and magnesium carbonate to which he gave the name dolomite in honour of his friend, while the light-coloured rock that contained it was subsequently named dolomia.

	Early Understandings Of Plant Growth
		He concluded that atmospheric air was essential for plant growth.
		A significant enlightenment in the understanding of plant nutrition was made by Theodore de Saussure (1767-1845) when he demonstrated that hydrogen and oxygen from water and carbon dioxide from the air contributed to the dry matter content of plants and that these sources were more important than humus.
		This Swiss scientist also showed that for normal nutrition, plants must take up, in dilute concentration, nitrates and other mineral matter from the soil.

		In 1804, a Swiss scientist, Nicholas Theodore de Saussure, by means of further carefully conducted experiments concerning the weight of plants, found that plants carrying on photosynthesis increased in weight by more than the amount of carbon dioxide they consumed.
		Nicholas de Saussure thought of water, too, and by precise measurements on plants was able to demonstrate that water was used by plants in photosynthesis.
		Building on this idea, Theodor Schwann and Matthias Schleiden stated that cells make up the basic structure of all living things and that these cells act independently yet function together as a unit.

		It then became evident that the "pure air" that plants release is oxygen.
		A complete elementary picture of plant nutrition was first achieved in 1804 by the Swiss scientist Theodore de Saussure (1767-1845).
		In his book Chemical Researches on Vegetation, de Saussure showed conclusively that green plants produce oxygen only when they consume carbon dioxide from the air, and that its uptake adds carbon to the plant.

	All about minerals
		In 1799 the French chemist Antoine Lavoisier - the father of nutrition research - predicted that scientists would isolate 'elements' from the soil.
		In 1804 Theodore de Saussure, another Frenchman, demonstrated that the mineral content of the soil affected the mineral content of the plants grown in that soil.
		Since then science has gradually shown that mineral after mineral was part of the body's vital functions and therefore we had to consume them through our diet in order to survive.

		The course focuses in particular on the relationship between violence and subjectivity and on questions of memory, trauma, and history: we will read these novels as responses to a set of disorienting and disturbing historical events.
		In this course, we cross-examine some of the most compelling modern fiction and film from Russia, Eastern and Western Europe, Latin and North America, focusing on the relation between dream, delirium, death, displacement, deviance, dissent and creativity.
		Taking an interdisciplinary as well as cross-culturally comparative approach to these critical modernist writers, we consider the dreamed city and delirious consciousness that structures much of modernist fiction in relation to other arts, particularly film (viewing early and avantgarde work by filmmakers ranging from Fritz Lang and Dziga Vertov to Stan Brakhage and Ingmar Bergman).
