Can anyone give me a list of 10 foreign and 10 filipino scientist and his/her contribution in chemistry?



Answer:
FOREIGN CHEMISTS

Emil Abderhalden - a Swiss biochemist and physiologist. He was born in Oberuzwil in the Canton of St. Gallen in Switzerland. Emil Abderhalden studied medicine at the University of Basel and received his doctorate in 1902. He then studied in the laboratory of Emil Fischer and worked at the University of Berlin. In 1911 he moved to the University of Halle and taught physiology in the medical school. From 1931 to 1950, he was president of the German Academy of Natural Scientists Leopoldina. During World War I, he established a children's hospital and organized the removal of malnourished children to Switzerland. Subsequently, he resumed his research into physiological chemistry and began to study metabolism and food chemistry.

Richard Abegg- a German chemist and pioneer of valence theory. Because of his research he proposed that the difference of the maximum positive and negative valence of an element tends to be eight. This has become to be called Abegg's rule. He was a gas balloon enthusiast and this is what caused his death at the age of 41 when he crashed in his balloon Schlesien.rom 1901, Abegg was active with an electrochemistry journal as editor.Abegg introduced the concept of the electro-affinity into chemistry and made the basis for the handbook of the inorganic chemistry (1905–1939). In 1904, Abegg formulated the valence rule, after which the highest positive and highest negative electro-valence of an element yields 8 altogether. This is called called Abegg's rule.

Amedeo Avogadro-Lorenzo Romano Amedeo Carlo Avogadro, Count of Quaregna and Cerreto (August 9, 1776–July 9, 1856) was an Italian savant chemist, most noted for his contributions to the theory of molarity and molecular weight. As a tribute to him, the number of atoms of one mole of a substance, 6.02 \times 10 ^ {23} is known as Avogadro's number.

Johannes Nicolaus Brønsted- a Danish physical chemist. He received a degree in chemical engineering in 1899 and his Ph. D. in 1908 from the University of Copenhagen. He was immediately appointed professor of inorganic and physical chemistry at Copenhagen. In 1906 he published his first of many papers on electron affinity. In 1923 he introduced the protonic theory of acid-base reactions, simultaneously with the English chemist Thomas Martin Lowry. The same year, the electronic theory was proposed by Gilbert N. Lewis, but both theories are commonly used.He became known as an authority on catalysis by acids and bases. He has the Brønsted catalysis equation named after him. He also came up with the highly used theory of the proton donor along with Lowry. Brønsted theorised that as a hydrogen atom (always found in an acid) is ionized once dissolved in water, it loses its electron and becomes a proton donor. The hydroxide ion, which occurs when an alkali is formed when a substance is dissolved in water is called a proton receiver. This leads to a neutralization reaction where the ions combine creating hydrogen hydroxide, otherwise known as water. The pH scale may be interpreted as "power of hydrogen", and the definition is based on the work of Brønsted and Lowry.

Robert Bunsen-a German chemist. His laboratory assistant, Peter Desaga perfected the burner that was later named after Bunsen, which was originally invented by British chemist/physicist Michael Faraday. He also worked on emission spectroscopy of heated elements. Together, he and Gustav Kirchhoff discovered the elements cesium and rubidium. He is considered the founder of modern gasanalytical methods.

Melvin Calvin-a chemist most famed for discovering the Calvin cycle (along with Andrew Benson), for which he was awarded the 1961 Nobel Prize in Chemistry. He spent virtually all of his five-decade career at the University of California, Berkeley.

Robert Boyle-n Anglo-Irish natural philosopher, chemist, physicist, inventor, and early gentleman scientist, noted for his work in physics and chemistry. He is best known for the formulation of Boyle's law. Although his research and personal philosophy clearly has its roots in the alchemical tradition, he is largely regarded today as the first modern chemist. He is very famous in the science world for being the first scientist that kept accurate experiment logs. Among his works, The Sceptical Chymist is seen as a cornerstone book in the field of chemistry.

Marie Curie-aka Madame Curie; November 7, 1867 – July 4, 1934) was a Polish-French physicist and chemist. She was a pioneer in the field of radioactivity, the first twice-honored Nobel laureate (and still today the only laureate in two different sciences), and the first female professor at the Sorbonne.

Henry Cavendish-a British scientist noted for his discovery of hydrogen or what he called "inflammable air". He described the density of inflammable air, which formed water on combustion, in a 1766 paper "On Factitious Airs". Antoine Lavoisier later reproduced Cavendish's experiment and gave the element its name.

John Dalton-an English chemist and physicist, born at Eaglesfield, near Cockermouth in Cumbria. He is best known for his advocacy of the atomic theory and his research into colour blindness (sometimes referred to as Daltonism, in his honour).

Around 1790 Dalton seems to have considered taking up law or medicine, but his projects were not met with encouragement from his relatives, and he remained at Kendal until, in the spring of 1793, moving to Manchester. Mainly through John Gough, a blind philosopher to whom he owed much of his scientific knowledge, Dalton was appointed teacher of mathematics and natural philosophy at the Manchester Academy. He remained in that position until the college's relocation to York in 1803, when he became a public and private teacher of mathematics and chemistry.

FILIPINO CHEMISTS

Daniel Dingel- For more than three decades now, Daniel Dingel has been claiming that his car can run with water as fuel. An article from the Philippine Daily Inquirer said that Dingle built his engine as early as 1969. Dingel built a car reactor that uses electricity from a 12-volt car battery to split the ordinary tap water into hydrogen and oxygen components. The hydrogen can then be used to power the car engine. Dingel said that a number of foreign car companies have expressed interest in his invention. The officials of the Department of Science and Technology (DOST) have dismissed Dingel's water-powered car as a hoax. In return, Dingel accused them of conspiring with oil producing countries. Dingel, however, was the not the only man on earth who is testing water as an alternative fuel. American inventors Rudolf Gunnerman and Stanley Meyer and the researchers of the U.S. Department of Energy's National Renewable Energy Laboratory have been pursuing similar experiments.

Dr. Abelardo Aguilar- A Filipino scientist reportedly discovered erythromycin in 1949. He was Dr. Abelardo Aguilar who died in 1993 without being recognized and rewarded for his discovery. Reports said Aguilar discovered the antibiotic from the Aspergillus species of fungi in 1949 and sent samples to Indiana-based pharmaceutical firm Eli Lilly Co. The drug firm allegedly registered the propriety name Iloson for the antibiotic in honor of Iloilo province where Aguilar discovered it. In 1952, Eli Lilly Co. began the commercial distribution of Iloson, which was sold as an alternative to penicillin. Erythromycin, the generic name of Iloson, was reportedly the first successful macrolide antibiotic introduced in the US.

Edgardo Vazquez- Edgardo Vazquez won a World Intellectual Property Organization (WIPO) gold medal in 1995 for developing a modular housing system. Such a system called Vazbuilt is reportedly capable of building within weeks a house with prefabricated materials that can withstand typhoons and earthquakes. Ironically, Vasquez is not getting enough support from the Philippine government to propagate his technology, which could help provide shelter to some five million Filipino families without their own homes. Vazquez is the national president of the Filipino Inventors Society.

Rudy Lantano Sr.- In 1996, Rudy Lantano Sr., a scientist from the Philippine Department of Science and Technology (DOST), won the World Intellectual Property Organization (WIPO) gold medal for developing Super Bunker Formula-L, a revolutionary fuel half-composed of water. The mix burns faster and emits pollutants, 95 percent less than those released to the air by traditional fuel products. The inventor said his invention is a result of blending new ingredients and additives with ordinary oil products through agitation and mixing, which is a very safe process. The initial plan was to commercially produce two million liters of Alco-Diesel, two million liters of Lan-Gas and an unlimited quantity of Super Bunker Formula-L each day for customers in Luzon.

Dr. Virgilio Malang- Dr. Virgilio Malang won a gold medal for his invention "Psidium Guajava Effervescing Gynecological Insert", a silver medal for his "Patient Side-Turning Hospital Bed", and three bonze medals for his inventions "external vaginal cleanser", "light refracting earpick", and "broom's way of hanging" at the Seoul International Fair in held South Korea in December 2002. There were 385 inventions from 30 countries that joined the competitions.

Ruperta David- Contrary to popular belief, there was no fish sauce or Patis yet during the Spanish occupation. Patis began to become a part of most Filipinos' diet only after the Japanese occupation. Here is an account of how an enterprising lady discovered the fermentation of Patis. Immediately after the war, the family of Ruperta David or Aling Tentay started a dried fish business. One day, Aling Tentay stored in jars some salted fish that turned into fragments even before they dried. While in jars, the fish fragments turned into a liquid substance that tasted like our Patis today. Thus the beginning of the thriving Patis business of Aling Tentay, which was officially registered in 1949 and is known today as Tentay Food and Sauces Inc. (Source: Philippine Daily Inquirer)
