One of the greatest scientists of the 1700s and 1800s was a man named Joseph L. Proust. He was a French chemist who was born on September 26, 1754 in Angers, France and died on July 5, 1826 in Angers, France. Proust changed science as everyone before him knew it. His ideas at the time were not held too highly for what they were. Nowadays, people view him as one of the greatest chemists of the past in terms of atomic structure. He is well known for his theory of definite composition that he came up with in 1793. This theory states that the percent composition of any sample of a substance is the same. In order to come up with this theory, Proust conducted a series of experiments with a lot of research behind it. One of the most successful experiments that backed up his theory was with the oxides of iron in 1797. He started out his life as the second son of an apothecary, Joseph Proust. As a child he worked to become an apothecary like his father. He had worked for this goal in Angers first and then in Paris. Proust received his education in his early years from his godparents and extended his education at the local Oratorian college. At the time, he was apprenticed to his father to …show more content…
They never had any children. While in Segovia, he started to publish his papers on definite proportions. In 1816, Proust was elected to the French Academy of Sciences to succeed Louis Bernard Guyton de Morveau. After his wife died in 1817, he moved back to Angers where he took over a pharmacy owned by his brother, Joachim, who was poor in health. After this in 1819, he was made the chevalier of the Legion of Honour and he was granted a pension by Louis XVIII in 1820. Overall, Proust’s work changed science forever because scientists could now use the information that no matter what the percentage of composition that a sample of a substance contains, it will be the same for that
The cathode ray tube was invented in 1875 by the name of Sir Williams Crooke. Yet he wasn’t the one to make the big discovery. In 1897, a man by the name of J.J. Thompson conducted a series of experiments to prove the existence of subatomic particles. He wasn’t 100% correct with all of his claims he made but broke the theory John Dalton stated that the smallest form matter could be broken down to was an atom. Having shown the world that there was smaller than an atom, it later caused others to question and dive even deeper.
and opened doors for later scientists that were in his field of organic synthesis. He was a
The chemist I have chosen is Antoine Laurent Lavoisier. As you might know, he was a fabulous chemist. Antoine Lavoisier is famous for formulating the theory of the chemical reactivity of oxygen. He also co-authored the modern system for the nomenclature of chemical substances. I have chosen this chemist because he is not one of those people that boast about all their accomplishments, but his achievements are crucial to science development. Antoine kept his accomplishments to himself. All of his achievements are fascinating to me. In this biography, I will be talking about his background, main accomplishments, and my opinion about his interesting story.
Louis Pasteur was born December 271822 in Dole, France. When he was five, his family moved to Arbois, France. He attended college in Paris and received a Doctor of Science degree in 1847. He began teaching chemistry at the University of Strasbourg, where he met his wife, Marie Laurent, who shared Pasteur’s interest in science. Marie and Pasteur married in 1849 and had five children, two of which survived to adulthood. Pasteur eventually went on to instruct chemistry and became dean of the school of science at the University of Lille.
Theodore W. Richards received the nobel prize in 1914 for his “accurate determinations of the atomic weight of a large number of chemical elements.” (Source ) He was born January 31st, 1868 in Germantown, PA, USA. William Trost Richards, his father, was a very famous landscape artist at the time and his mother, Anna, won her fame through poetry. While growing up, Theodore’s parents brought him to England and France. At the age of fourteen he was educated by his mother.
Although he was born in Cote-d’Or he was raised in Paris. His mother owned a charcoal-distribution business that she inherited from her parents. At the time of his birth his dad was an administrator for the French army but soon joined his mom. The family came up with the name Eiffel from the Eifel Mountains of which they came. The family name was not changed to Eiffel formally until 1880. Due to his mother’s job, he lived with his grandmother, but still remained close with his mother. Catherine Eiffel sold the business in 1843 and retired on the proceeds.
Laplace was the child of a worker agriculturist. At a young age, he immediately demonstrated his scientific capacity at the military foundation in Beaumont. In 1766 Laplace entered the University of Caen, yet he cleared out for Paris the following year, without taking a degree. He touched base with a letter of proposal to the mathematician Jean d'Alembert, who helped him secure a residency at the École Militaire, where he educated from 1769 to 1776.
...hat have many contibutions to different parts of science such as fluid mechanics. While some of them have worked on theorems or theories about the functioning of anything about the life, some parts of scientists have tried to work on making inventions. Some of them are well-known scientists and many people know a lot of information about them. However, there are many other scientists that have stayed in the background. One of them is Henri De Pitot. It is necessary to thank to whole scientific family.
his education at the Collège Royal in Lyons, then transferred to the Lycée Louis-le-Grand in Paris. It was at the latter that he began to write poetry and develop moods of depression, and in 1839 he was expelled for being unruly. Eventually he became a student of law at the Ecole de Droit but in reality lived a “free life” and it was here that he came into contact with the literary world for the first time. He also contracted VD, which was to be the cause of his death years later.
recognized as a writer. He became one of the most famous and well paid French
At the age of 21, his intestinal operation led to appendicitis. Henri was on bed rest for most of 1890 and to help him occupy his time, his mother bought him a set of paints. That was the turning point in Henri’s life. He decided to give up his career in law for a career in art. Matisse himself said, “It was as if I had been called. Henceforth I did not lead my life. It led me” (Getlein 80). Soon after, Henri began to take classes at the Academie Julian to prepare himself for the entrance examination at the Ecole des Beaux-Arts (Essers 7). Henri failed his first attempt, leading to his departure from the Academie. He then enrolled at the Ecole des Arts decoratifs and that is where his friendship with Albert Marquet began. They started working alongside of Gustave Moreau, a distinguished teacher at Ecole des Beaux-Arts, even though they had not been accepted (Essers 12). In 1895, Henri finally passed the Beaux-Arts entrance examination and his pathway to his new career choice had officially begun.
Etienne Pascal was very concerned about his son becoming an educated man. This is why he decided to teach his son on his own. He brought a young Blaise to lectures and other gatherings. He decided Blaise would not study math until age 15. When he made this decision he took all the math books out of the family home; however, this did not stop a curious Pascal. At age twelve, he started to work on geometry by himself. Blaise’s father finally started to take him to mathematical gatherings at "Academic Parisienne." At the age of 16, Pascal began to play an active role in "Academic Parisienne," as the principal disciple of Girard Desargues, one of the heads of "Academic Par...
Although his father had other plans for him, Pasteur had the opportunity to attend a preparatory school in Paris before going on to Ecole Normale, however when he got to Paris he became very homesick and his father soon arrived to take him home. After returning to Arbois Pasteur attended a local school named Besancon where he worked very hard and became one of the top students in his class. In 1842 Pasteur passed the admission tests to attend Ecole Normale however he was rated fifteenth of twenty-two candidates and this was not good enough to satisfy him. He continued to study and finally in 1843 Pasteur sailed through his admission tests and was awarded fourth place among the other candidates (Burton, 7-11).
...st important scientists in history. It is said that they both shaped the sciences and mathematics that we use and study today. Euclid’s postulates and Archimedes’ calculus are both important fundamentals and tools in mathematics, while discoveries, such Archimedes’ method of using water to measure the volume of an irregularly shaped object, helped shaped all of today’s physics and scientific principles. It is for these reasons that they are remembered for their contributions to the world of mathematics and sciences today, and will continue to be remembered for years to come.
Dalton was the first person to develop a scientific atom theory, the ancient Greeks had ideas about the atom but could not prove it scientifically.
