He did not analyze any of these compounds, however. In , Runge published the first systematic study of chromatography: He also noted the ability of belladonna to induce long-lasting dilation of the pupil of the eye mydriasis , and he developed a process for obtaining sugar from beet juice.

He investigated dry distillation and the composition of matter. Born 8 Feb ; died 27 Sep at age As the son of a saltpeter manufacturer from Dijon, he grew interested in chemistry and was apprenticed to a pharmacist.

While in military service as a pharmacist, he became the first to isolate pure morphine from opium He returned to assist at his father's saltpeter business, where the ashes of kelp seaweed were leached for sodium and potassium salts using sulphuric acid.

In , from the mother liquor, he observed rising clouds of purple vapour which condensed on cold surfaces as dark crystals with a metallic lustre.

He thought these could be a new element, but lacked ability to fully confirm his suspicion. Born 8 Feb ; died 7 Nov at age Deluc was educated in mathematics and the natural sciences.

While a businessman in Switzerland during the first half of his life, during his travels, he collected mineral and plant specimens in the Alps.

A commercial failure in induced him to emigrate to England and devote himself to science, his long-time avocation. He held the doctrine of catastrophism to explain present geological formations, opposing the view that present processes have acted continuously during past ages.

Born 8 Feb ; died 17 Mar at age His talents were prodigous, spanning medicine, biology, physiology, mechanics, physics, astronomy, and oceanography.

His principal work, Hydrodynamica , publ. Bernoulli's famous theorem, based on the conservation of energy, states the total mechanical energy of the flowing fluid remains constant.

This total is comprised of the energy associated with fluid pressure, the gravitational potential energy of elevation, and the kinetic energy of fluid motion.

Born 8 Feb ; died 26 Jan at age Huet wrote a number of philosophical works that asserted the fallibility of human reason in addition to scientific work in the fields of astronomy, anatomy, and mathematics.

Nature bears long with those who wrong her. She is patient under abuse. But when abuse has gone too far, when the time of reckoning finally comes, she is equally slow to be appeased and to turn away her wrath.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again.

They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day.

I cannot recall the last time something like that happened in politics or religion. I used to wonder how it comes about that the electron is negative.

There is no reason whatever to prefer one to the other. Then why is the electron negative? It is the facts that matter, not the proofs.

Physics can progress without the proofs, but we can't go on without the facts Died 8 Feb at age 65 born 29 Jul Dr Henry Albert Howard "Harry" Boot was an English physicist , who worked with John Randall developing the cavity magnetron , the microwave-generating device used in radar.

This made a major contribution to winning WWII. Earlier magnetrons made in the 's gave low power output. By Feb , advances by Randall and Boot in the design of the small-sized cavity magnetron, produced centimeter wavelengths at much higher power, which allowed radar to detect smaller objects.

In turn, this more compact equipment with a smaller antenna permitted easy mobile installation of high-resolution radar in aircraft.

Died 8 Feb at age 78 born 5 Jun He first conceived the idea of holography in using conventional filtered-light sources. Because such sources had limitations of either too little light or too diffuse, holography was not commercially feasible until the invention of the laser , which amplifies the intensity of light waves.

He also did research on high-speed oscilloscopes, communication theory, physical optics, and television. Gabor held more than patents. Some sources give 9 Feb Died 8 Feb at age 88 born 13 Sep In his early research, he studied plant pigments and synthesized anthocyanins and flavones.

Later, working with alkaloids, he discovered the structures of morphine and strychnine Scientist Extraordinary, by Trevor I. Died 8 Feb at age 75 born 14 Feb His work on supernovas produced an improved theoretical understanding of these infrequent stars that have exceptional brightness for a short period.

His career included contributions to jet propulsion and the physics of crystals, liquids and gases but he is best known for astrophysics.

He searched for supernovas, and calculated their frequency as rare as one per millenium per typicl galaxy. After Lev Landau proposed extremely dense and compact neutron stars in , Zwicky with Walter Baade suggested that they might be at the core of supernovas, which contributed to the development of the theory of stellar evolution.

His abrasive personality delayed the acceptance of his innovative interpretations. Died 8 Feb at age 63 born 18 Aug Frederick Charles Bawden was an English plant pathologist whose research interest was in plant viruses, and how best to ensure that a farmer could grow healthy and productive crops.

With his associates, in , he discovered that the tobacco mozaic virus contained ribonucleic acid RNA.

Nucleic acids were known to be present in all cells, but this was the first time that RNA was observed in a virus, which is a subcellular infectious agent.

Nucleic acids have subsequently been found in all identifiable viruses. Since the tobacco mosaic virus was first identified by Martinus Beijerinck , it has proved particularly amenable to laboratory research.

Bawden travelled a number of times to Africa to help solve problems with diseased crops. Died 8 Feb at age 75 born 8 Oct Kretschmer analyzed over 4, criminal cases using his 3 body type model: His conclusion was that were is a greater number of violent criminals who correspond to the athletic type, while the asthenic are more likely to be involved in petty theft and fraud.

Finally, Kretschmer found that the pyknic tended toward crimes involving deception and fraud but were also sometimes involved in violent crimes.

Died 8 Feb at age 66 born 8 Jan Walther Wilhelm Georg Franz Bothe was a German physicist who developed the coincidence method of detecting the emission of electrons by x-rays in which electrons passing through two adjacent Geiger tubes at almost the same time are registered as a coincidental event.

He used it to show that momentum and energy are conserved at the atomic level. In he applied the method to the study of cosmic rays and was able to show that they consisted of massive particles rather than photons.

This research brought him a share with Max Born in the Nobel Prize for In , he observed a strange radiation emitted from beryllium when it was exposed to alpha particles, later identified by Chadwick as consisting of neutrons.

He built Germany's first cyclotron Died 8 Feb at age 53 born 28 Dec He invented game theory, the branch of mathematics that analyses strategy and is now widely employed for military and economic purposes.

During WW II, he studied the implosion method for bringing nuclear fuel to explosion and he participated in the development of the hydrogen bomb.

He also set quantum theory upon a rigorous mathematical basis. The Scientific Genius Who Pioneered Died 8 Feb at age 78 born 21 Jan At first, he considered pharmacy but turned to chemistry.

He earned a Ph. He was interest in finding a better pain reliever for his father's chronic rheumatism, to replace the use of salicylic acid which had a bad taste and caused stomach upset.

On 10 Aug , he formed a derivative, acetylsalicylic acid by acetylating salicylic acid with acetic acid. Company testing showed it was a safe and efffective drug for pain relief, lowering fever, and as an anti-inflammatory.

It was marketed from Hoffman's name is on the patent, and he became head of the pharmaceutical marketing department, but received no financial share of its worldwide success.

In , he retired to Switzerland. Died 8 Feb at age 64 born 8 Aug English biologist who published the first English translation of Gregor Mendel 's work on heredity which he confirmed with his own experiments, and further demonstrated that heredity was apparent in animals as well as plants.

His support of Mendel was as effective in awakening modern understanding of heredity as Thomas Huxley provided for Charles Darwin on evolution.

Bateson coined the term genetics for the new science. He recognized gene linkage by which some characteristics are inherited together, rather than all characteristics being inherited independently as later explained by Thomas Morgan.

Earlier, he had contributed to understanding of embryology when, in , proposed that the chordates evolved from primitive echinoderms. Died 8 Feb at age 78 born 21 Dec While an army officer in Siberia , he studied the native animals, made geographical surveys, and examined the effects of the Ice Age in Asia and Europe.

His investigation of the structural lines of mountain ranges revised the cartography of eastern Asia. He wrote a series of articles against social Darwinism and its tenet of the benefits of competition.

Kropotkin asserted that sociability characterized animals. Thus, he held, cooperation rather than struggle guided the evolution of man and human intelligence.

His greatest renown, though, was as an anarchist. A Factor of Evolution, by Peter Kropotkin. Jean Jacques Theophile Schloesing.

Died 8 Feb at age 94 born 9 Jul French soil scientist who with Achille Muntz proved that nitrification is a biological process in the soil by using chloroform vapors to inhibit the production of nitrate.

The process involved sensitizing a photoconductive surface to light by giving it an electrostatic charge Carlson developed it between and , and initially described it as electrophotography It was immediately protected by Carlson with an impenetrable web of patents, though it was not until that he was able to obtain funding for further development.

In he sold the commercial rights for his invention to the Haloid Company, a small manufacturer of photographic paper which later became the Xerox Corporation.

Born 8 Feb ; died 25 May at age American psychiatrist and educator who developed the Austrian psychologist Alfred Adler 's system of individual psychology into a pragmatic method for understanding the purposes of reprehensible behaviour in children and for stimulating cooperative behaviour without punishment or reward.

Born 8 Feb ; died 23 Jan at age Roman Catholic priest and cultural anthropologist who advocated a comparative, historical approach to understanding cultural phenomena and whose investigations of hunting and food-gathering tribes produced theories on the origin and development of society.

Born 8 Feb ; died 27 Aug at age British zoologist and collector 2nd Baron Rothschild of Tring who founded the Walter Rothschild Zoological Museum , Tring, which opened to the public in and is now part of the Natural History Museum.

His interest in natural history began when he was a child, collecting butterflies. Numerous species and sub-species of animals were named after him.

From Tring, he issued Novitates Zoologicae , and published scores of scientific papers. He was the eldest son of financier Nathan Mayer Rothschild, 1st Baron Rothschild, whom he disappointed by devoting his life to natural history instead of the family banking business.

He received his titles on the death of his father in Birds, Butterflies and History, by Miriam Rothschild. Born 8 Feb ; died 12 Feb at age Russian-born American chemist who initiated the study of free radicals in chemistry when in he prepared the first authentic one, triphenylmethyl.

Organic free radicals are essential to body functioning as well as being implicated in aging and diseases. Also, they play a major role in the production of plastics and other widely used synthetic materials.

Organic free radicals contain a form of carbon with an unpaired electron which allows the radical to react readily with another molecule.

Until Gomberg synthesized triphenylmethyl, free radicals containing carbon had been thought not to exist. Gomberg's discovery led to modern theories of the structure and reactivity of organic molecules, and led to the development of an entire field of research.

Born 8 Feb ; died 2 Feb at age In his final version of the periodic table he left gaps, foretelling that they would be filled by elements not then known.

He predicted the properties of three of those elements. New Style dates used by Dict. His Life and His Work, by O. Booklist for Dmitry Mendeleyev.

Born 8 Feb ; died 16 Feb at age He and Alfred Russel Wallace left England in to explore and collect insects in the Amazon basin.

Bates spent 11 years in Amazonia amassing large collections of insects that were sent back to museums and collectors in Europe. Bates was quick to embrace Darwin's and Wallace's theory of evolution by natural selection.

Bates' own theory of mimicry, which now bears his name Batesian mimicry , provided evidence for evolution by natural selection.

Born 8 Feb ; died 25 Mar at age In the course of his research on synthetic dyes, he isolated and named several important components of coal-tar oil, among them carbolic acid , now called phenol , pyrrole, rosolic acid aurin , and cyanol aniline.

He did not analyze any of these compounds, however. In , Runge published the first systematic study of chromatography: He also noted the ability of belladonna to induce long-lasting dilation of the pupil of the eye mydriasis , and he developed a process for obtaining sugar from beet juice.

He investigated dry distillation and the composition of matter. Born 8 Feb ; died 27 Sep at age As the son of a saltpeter manufacturer from Dijon, he grew interested in chemistry and was apprenticed to a pharmacist.
