⏹ Brandt, Georg

Swedish chemist ( 1694 - 1768 )
Brant received his education in Leiden, where he studied medicine and chemistry, and was one of the students of Boerhaave (Boerhaave), the Dutch physician. He entered the door of fame for his discovery of the element cobalt », Brant's work and his perseverance and perseverance were admired by his contemporaries.

⏹ Brand Hennig Brand

German chemist (from the seventeenth century).
Brand began his life in the military, then went on to study chemistry, and was eager to search for a liquid that turns silver into gold. Brand began his experiments on urine, which led him to discover the element phosphorus.

⏹ Brahi Tekko (Tigha)
Brahe, Tycho (Tyge)

Danish astronomer (1564-1601).
Brahe learned in Copenhagen, where he specialized in law (law), then completed his education in Leipzig and settled after that in an astronomer job, so he built an observatory in Hveen, then he moved to Prague to reside in the custody of Emperor Rudolf.
Brahe mistakenly believed that the Earth was the center of the solar system, yet his painstaking work at the observatory was of great help to later astronomers by grounding Kepler's laws.
Brahe managed to discover a new star in the Cassiopeia galaxy (Cassiopela) in the year 1752.
In the year 1602, the famous astronomer Kepler published in Prague the most important works of Brahe in a book entitled: Astronomie Instaurata Progymnasmata.
In addition, Brahe designed and manufactured a number of astronomical observing machines, including the Quadrante
And the sextant, although the latter was known in the Arab East before that.

⏹ Brown, Alkasaiber Karam
Brown, Alexander Chrome

Scottish chemist (1838 - 1922).
Brown received his education in Edinburgh, London, Heidelberg, and Mazeburg · Then he worked as a professor of chemistry in Edinburgh until he reached the age of seventy, when Brown was chosen as a Fellow of the Royal Societies.
He has become famous for his research in equilibrium (isomerism, i.e. the similarity of compounds of chemical difference in terms of components and their ratios with at least one of their chemical or physical characteristics) and in organic sulfur compounds. Brown's name is called the law of substitution reaction in benzene derivatives • Brown has developed new structural formulas for benzene compounds.

⏹ Brown, Robert Robert, Brown

Scottish botanist (1773-1858).
Brown studied medicine in Edinburgh and was interested in natural studies, so he participated in the Flinders campaign to Australia in the year 1800, and he collected four thousand varieties of plants and brought them back to his homeland. Australia Brown was the first British writer to use the natural system in classification instead of the Swedish Linnaeus system (Linnaeus lived from 1707 to 1778). Brown was made a Fellow of the Royal Society and then became Curator of the Botany Department of the British Museum.
Brown noticed the movement of colloidal particles in solutions and gave his name to this movement and called it the Brownian movement. This discovery led to the provision of practical evidence on the molecular structure of liquids and to other important chemical discoveries. Brown was awarded the Copley Medal.

⏹ Brown-Sequard, Charles Edward
Brown Sequard, Charles Edward

British physiologist
( 1894-1817 )
Brown-Sequard descends from Americanized French (French-American), and he received his education in Paris, then worked as a professor at Harvard and Paris.
Finally, he worked as a professor of experimental medicine at the College de France • Braun-Sequard conducted valuable studies on the spinal cord and has more famous research on internal secretions in the body, which led to the successful treatment of dry skin, hair and general degeneration resulting from hypothyroidism. This disease is known as “myxedema”.
Concerning the extension of life, Brown-Sequard came out with a proposal that was unsuccessful in his time, as he referred to the use of sheep testicular fluids for this purpose, and thus he raised a wave of criticism from the scholars of his time who failed to reach the scientific glory he reached.
