  Jean Senebier - Wikipedia, the free encyclopedia
Jean Senebier (May 6, 1742 - July 22, 1809) was a Swiss pastor who wrote many works on vegetable physiology.
He was born at Geneva, and is remembered for his contributions to the understanding of the influence of light on vegetation.
Jan Ingenhousz proved the simultaneous disappearance of carbonic acid; but it was Senebier who clearly showed that this activity was confined to the green parts, and to these only in sunlight, and first gave a connected view of the whole process of vegetable nutrition in strictly chemical terms.

 Jean Senebier Biography / Biography of Jean Senebier World of Biology Biography
Jean Senebier was a Swiss botanist who is credited with being the first scientist to demonstrate the principle of photosynthesis.
Senebier, the son of merchant Jean-Antoine Senebier, was born in Geneva, Switzerland, on May 6, 1742.
Senebier was the first to discover that plants absorb carbonic acid gas and release oxygen.

 Senebier, Jean - Hutchinson encyclopedia article about Senebier, Jean   (Site not responding. Last check: 2007-10-24)
Swiss botanist, plant physiologist, and pastor, whose research on photosynthesis (the process by which green plants use light energy to make carbohydrates) showed that ‘fixed air’ (now known to be carbon dioxide) was converted to ‘pure air’ (oxygen) in a light-dependent process.
Senebier showed that it was the light and not the warmth of sunlight that was necessary for photosynthesis to occur, and that photosynthesis does not occur in boiled water from which the gases have been excluded.

In 1782, Senebier demonstrated that the combustion-supporting gas, oxygen, is formed by a plant, while carbon dioxide is absorbed from the air.
Senebier’s results did not prove that the oxygen could not come from the water.
Maybe the oxygen from the water went somewhere else in the plant, and the oxygen came from the carbon dioxide, which Senebier did show was needed for the process to occur.

It can be argued that Jean Senebier (1742-1809) did the most significant plant physiology experiments ever conducted.
Senebier had the good fortune to be both wealthy and curious and to live in a city (Geneva) with a thriving scientific community.
Senebier, Hales and many other scientists represented in the collection remind us of how important curiosity and a good working environment are for scientific enquiry.

 Science in Christian Perspective
Epigenesis, with its emphasis on internal transformations by a sequential, orderly differentiation, was, for Senebier, clearly a threat to theism.
Epigenesis (including, of course, chemical preformation) has become so deeply embedded in biology since Senebier's time that no one today questions the idea that organisms develop gradually from an ovum, even though this can scarcely be observed with ease.
Happily, Senebier is remembered today for his meticulous experiments on photosynthesis during the 1780s, not for his dismay over what happens in an egg.

Swiss-born physiologist and physician Jean-Louis Prévost was a pioneer in the anatomy of the reproductive system, as well as hematology, or study of the blood.
In the early years of the nineteenth century, it was not unusual for young men to begin studies in theology and later turn to medicine.

Jean Baptiste van Helmont rejects the idea that plants are fed by the soil.
Jan Ingelhousz discovers that only the green parts of plants release oxygen, and that oxygen is only given off when the plants are lit.
Jean Senebier shows that green plants consume carbon dioxide and give off oxygen under the influence of sun light.

 Jan Ingen-Housz's experiment
At the end of the eighteenth century, a Swiss minister named Jean Senebier worked out that another gas, carbon dioxide, is involved in photosynthesis.
The bigger the tree, the more charcoal (carbon) Senebier produced.
Senebier showed that the carbon came from the intake of carbon dioxide.

Starting with the historic discoveries of Joseph Priestley, Jan Ingenhousz, and Jean Senebier, this miniseries examines the absorption of light by plants and follows the energy pathways to the production of carbohydrates and other organic materials.
Programs also explore the Calvin cycle as it functions in carbon-3 and carbon-4 plants and the fluid transport system that delivers water and nutrients throughout the plant structure.

 The paper
Building on the work of Priestley, Jan Ingenhousz, a Dutch physician, demonstrated that sunlight was necessary for photosynthesis and that only the green parts of plants could release oxygen.
During this period Jean Senebier, a Swiss botanist and naturalist, discovered that CO2 is required for photosynthetic growth and Nicolas- Théodore de Saussure, a Swiss chemist and plant physiologist, showed that water is required.
It was not until 1845 that Julius Robert von Mayer, a German physician and physicist, proposed that photosynthetic organisms convert light energy into chemical free energy.

One might be so bold as to say that when it came down to it, Jean Senebier only ended up studying theology because he was not interested in the business career which his father had planned for him and because a political career would not have suited his character.
It was nonetheless a rare position since there were at that time only two, or at the most three, individuals to hold it.
