Biographical Sketch

Robert Hooke

hypertext transfer protocol: //www.gap-system.org/~history/Thumbnails/Hooke.jpg Robert Hooke ‘s male parent was John Hooke who was a minister of religion at All Saints Church in Freshwater on the Isle of Wight. Robert had a brother named John, the same as his male parent, who was five old ages older. Robert, like many kids of his twenty-four hours, had hapless wellness and was non expected to make maturity. Robert ‘s ain thoughts involved his experimental accomplishments and his mechanical accomplishments. He observed the workss, the animate beings, the farms, the stones, the drops, the sea, and the beaches around him. He was fascinated by mechanical playthings and redstem storksbills, doing many things from wood from a working clock to a theoretical account of a to the full rigged ship with working guns. Hooke had discovered works cells more exactly, what Hooke proverb were the cell walls in cork tissue. Hooke was besides a acute perceiver of dodos and geology.

Anton new wave Leewenhoek

Leeuwenhoek was born in Delft on October 24, 1632. His male parent was a basket-maker, while his female parent ‘s households were beer makers. Antony new wave Leeuwenhoek learned to crunch lenses, made simple microscopes, and began detecting with them. He seems to hold been inspired to take up microscopy by holding seen a transcript of Robert Hooke ‘s illustrated book Micrographia, which depicted Hooke ‘s ain observations with the microscope and was really popular. Leeuwenhoek looked at animate being and works tissues, at mineral crystals and at dodos. He was the first to see microscopic Foraminifera, which he described as “ small cockles no bigger than a harsh sand-grain.” He discovered blood cells, and was the first to see living sperm cells of animate beings. He discovered microscopic animate beings such as roundworms and rotifers.

Theodor Schwann

Theodor Schwann was born at Neuss near Dusseldorf on Dec. 7, 1810. At the University of Bonn, which he entered in 1829, he met Johannes Muller, the physiologist, whom he assisted in his experiments. Theodor Schwann ( 1810-1882 ) is considered a laminitis of the cell theory. He besides discovered pepsin ; the first digestive enzyme prepared from carnal tissue, and experimented to confute self-generated coevals. He isolated a substance responsible for digestion in the tummy ; the first enzyme prepared from carnal tissue, and named it pepsin. He studied musculus contraction and nervus construction, detecting the striated musculus in the upper gorge and the medulla sheath covering nervus cells. He coined the term metamorphosis, identified the function played by micro-organisms in the decomposition of organic affair, and formulated the basic rules of embryology by detecting that the egg is a individual cell that finally develops into a complete being.

Louis Pasteur

Pasteur was the descendent of coevalss of sixpences. He was Gallic chemist and microbiologist whose parts were among the most varied and valuable in the history of scientific discipline and industry. It was he who proved that micro-organisms cause agitation and disease ; he who pioneered the usage of vaccinums for hydrophobias, splenic fever, and chicken cholera ; he who saved the beer, vino, and silk industries of France and other states ; he who performed of import innovator work in stereochemistry ; and he who originated the procedure known as pasteurisation. . On the footing of these experiments, Pasteur elaborated his theory of molecular dissymmetry, demoing that the biological belongingss of chemical substances depend non merely on the nature of the atoms representing their molecules but besides on the mode in which these atoms are arranged in infinite.

James Watson & A ; Francis Crick

Francis Crick was educated near London. He studied natural philosophies in college and received a BS grade in the field. Interested in biological science, he decided to pitch his surveies to concentrate on the consequence of X raies on proteins. James Watson, on the other manus, was born and raised in Chicago, Illinois, and received a scholarship to analyze at the University of Chicago. He besides received a grade in fauna from Indiana University in Bloomington where he studied the consequence of X raies on bacteriums. BiographyShelf – Francis Crick & A ; James Watts Watson became intrigued with bring outing the construction of DNA. His involvement and research intensified when he met Francis Crick while working at the Cavendish Lab at the University of Cambridge. Both wanted to bring out a cistron ‘s true construction, and in 1953 after experimenting with composition board and paste, the two figured out that Deoxyribonucleic acid had to be composed of two double-helical constellations. Crick had been assigned to work on an experiment sing baccy bacteriums. He still had an overpowering impulse to work on calculating out the true construction of DNA, and while working on the baccy assignment, he found and located a virus utilizing an negatron microscope.

Linus Pauling

Linus Pauling Linus Carl Pauling was born in Portland, Oregon, on 28th February, 1901, the boy of a pharmacist, Herman Henry William Pauling, who, though born in Missouri, was of German descent, and his married woman, Lucy Isabelle Darling, born in Oregon of English-Scottish lineage. In 1921 he suggested, and attempted to transport out, an experiment on the orientation of Fe atoms by a magnetic field, through the electrolytic deposition of a bed of Fe in a strong magnetic field and the finding of the orientation of the Fe crystallizes by smoothing and etching the sedimentation, and microscopic scrutiny of the etch figures. With Professor Dickinson, he began in 1922 the experimental finding of the constructions of some crystals, and besides started theoretical work on the nature of the chemical bond.
