Mendeleev's discovery of the periodic law and his periodic table of the elements was first announced to European scientists in a short article in the german journal Zeitschrift fur Chemie (Journal of Chemistry) in 1869, which is on display. Mendeleev discovered the periodic law during the time he was engaged in writing the first edition of a chemistry textbook, Osnovy Khimii (Principles of Chemistry). Mendeleev based his periodic table on 'four aspects of matter' that revealed close relationships between certain chemical elements. These four aspects were isomorphism, the specific volumes of similar compounds or elements, the composition of compound salts, and relations among the atomic weights of elements. Since the periodic law was dependent upon the quantitative relation between atomic weight, as an independent variable, and an element's physical and chemical properties, Mendeleev in 1869 took up the problem of developing and entire 'natural system of elements'.

Izaak Maurits (Piet) Kolthoff (Father of Analytical Chemistry])

was a highly influential chemist, widely considered the Father of Analytical Chemistry. He was given this title based on his development of analytical chemistry as a modern science. His research dealt with analytical and physical chemistry . His mainresearch topics included potentimetry, conductometry, polarography, theory and application of indicators, acid-base equilibriaand titrations in aqueous and non-aqueous media, formation, properties and aging of precipitates, adsorption, coprecipitation, post-precipitation, and induced reactions. He is also credited in development of the polarograph, an instrument for recording polarization of electrolytes. During World War II he served as chairman of the Committee on Analytical research Methods and supervisor of three research projects for the U.S. Government on synethic or "cold process" rubber.

Lavoisier was an administrator of the FermeGénérale and a powerful member of a number of other aristocratic councils. All of these political and economic activities enabled him to fund his scientific research. At the height of the French Revolution, he was accused by Jean-Paul Marat of selling adulterated tobacco and of other crimes, and was eventually guillotined a year after Marat's death. Benjamin Franklin was familiar with Lavoisier, as they were both members of the "Benjamin Franklin inquiries" into Mesmer and animal magnetism.

Archibald Scott Couper (31 March 1831 – 11 March 1892) was a Scottish chemist who proposed an early theory of chemical structure and bonding. He developed the concepts of tetravalent carbon atoms linking together to form large molecules, and that the bonding order of the atoms in a molecule can be determined from chemical evidence.

Couper was the only surviving son of a wealthy textile mill owner near Glasgow. He studied at the universities of Glasgow and Edinburgh and intermittently in Germany during the years 1851-54. He began the formal study of chemistry at the University of Berlin in the fall of 1854, then in 1856 entered Charles AdolpheWurtz's private laboratory at the Faculty of Medicine in Paris (now the University of Paris V: René Descartes).

Sir Humphry Davy, 1st Baronet FRS MRIA FGS (17 December 1778 –29 May 1829) was an English chemist and inventor. He is probably best remembered today for his discoveries of several alkali and alkaline earth metals, as well as contributions to the discoveries of the elemental nature of chlorine and iodine. Berzelius called Davy's 1806 Bakerian Lecture On Some Chemical Agencies of Electricity "one of the best memoirs which has ever enriched the theory of chemistry." This paper was central to any chemical affinity theory in the first half of the nineteenth century. In 1815 he invented the Davy lamp, which allowed miners to work safely in the presence of flammable gases.

Wöhler is regarded as a pioneer in organic chemistry as a result of his (accidentally) synthesizing urea in the Wöhler synthesis in 1828. This discovery has become celebrated as a refutation of vitalism, the hypothesis that living things are alive because of some special "vital force". However, contemporary accounts do not support that notion. This Wöhler Myth, as historian of science Peter J. Ramberg called it, originated from a popular history of chemistry published in 1931, which, "ignoring all pretense of historical accuracy, turned Wöhler into a crusader who made attempt after attempt to synthesize a natural product that would refute vitalism and lift the veil of ignorance, until 'one afternoon the miracle happened'".Nevertheless, it was the beginning of the end of one popular vitalist hypothesis, that of Jöns Jakob Berzelius that "organic" compounds could only be made by living things.

Vauquelin was born at Saint-André-d'Hébertot in Normandy, France. His first acquaintance with chemistry was gained as laboratory assistant to an apothecary in Rouen (1777–1779), and after various vicissitudes he obtained an introduction to A.F. Fourcroy, in whose laboratory he was an assistant from 1783 to 1791.

At first his work appeared as that of his master and patron, then in their joint names; in 1790 he began to publish on his own, and between that year and 1833 his name is associated with 376 papers. Most of these were simple records of patient and laborious analytical operations, and it is perhaps surprising that among all the substances he analysed he only detected two new elements, beryllium in 1798 in beryl and chromium in 1797 in a red lead ore from Siberia. He also managed to get liquid ammonia at atmospheric pressure.

In 1853, at the precocious age of 15, Perkin entered the Royal College of Chemistry in London (now part of Imperial College London), where he began his studies under August Wilhelm von Hofmann.At this time, chemistry was still in a quite primitive state: although the atomic theory was accepted, the major elements had been discovered, and techniques to analyse the proportions of the elements in many compounds were in place, it was still a difficult proposition to determine the arrangement of the elements in compounds. Hofmann had published a hypothesis on how it might be possible to synthesise quinine, an expensive natural substance much in demand for the treatment of malaria. Perkin, who had by then become one of Hofmann's assistants, embarked on a series of experiments to try to achieve this end. During the Easter vacation in 1856, while Hofmann was visiting his native Germany, Perkin performed some further experiments in the crude laboratory in his apartment on the top floor of his home in Cable Street in east London. It was here that he made his great discovery: that aniline could be partly transformed into a crude mixture which when extracted with alcohol produced a substance with an intense purple colour.] Perkin, who had an interest in painting and photography, immediately became enthusiastic about this result and carried out further trials with his friend Arthur Church and his brother Thomas.

Joseph L. Proust was born on September 26, 1754 in Angers, France. His father served as an apothecary in Angers. Joseph studied chemistry in his father’s shop and later came to Paris where he gained the appointment of apothecary in chief to the Salpetriere.

Proust’s largest accomplishment was creating elements from water. He put hydrogen into the realm of science was disproving Berthollet with the law of definite proportions, which is sometimes also known as Proust's Law. Proust studied copper carbonate and created golD from zinc, the two tin oxides,and the two iron sulfides to prove this law. He did this by making artificial copper carbonate and comparing it to natural copper carbonate. With this he showed that each had the same proportion of weights between the three elements involved (Cu, C, O). Between the two types of the other compounds, Proust showed that no intermediate indeterminate compounds exist between them. Proust published this paper in 1794, but the law was not accepted until 1812, when the Swedish chemist Jöns Jacob Berzelius gave him credit for it.

Filipino Chemist - Dr. Julian BanzonThe work of famous Filipino chemist Dr. Julian Banzon is centered on agricultural pursuits. This includes the search and exploration of native Filipino raw materials, and how they can be used as possible renewable sources of fuels and chemicals in society. One of the agricultural products that he has turned his eye onto and studied extensively is the native coconut. Dr. Banzon managed to come up with a scientific process in which coconut oil can be extracted through chemical means, instead of the regular physical ways that are more costly and time-consuming. This was a huge improvement within the industry.

Another field of focus for Dr. Julian Banzon has been the use of natural plants or animal waste products as fuel for machinery or other purposes, as well as how sugarcane can be a natural source of ethyl esters. These can be isolated from the main sugarcane plant, and then be used as a natural substitute for other synthetic types of fuel, or in pharmaceuticals. Through his laboratory work, Dr. Banzon has been able to devise a variety of ways in which this can potentially be useful to society as a form of energy. He has also published reports on the varieties of Philippine vinegars and their uses, extensive studies of coconut oils, and how to use cassava root for fermentation purposes.

Francisco Quisumbing was a chemist who hailed from the Philippines. During his illustrious career, he created a new formula for ink, which was trademarked under the name, Quink.

• This chemist created his own corporation, known as Philippines Ink Corp., after the Second World War; however, he became frustrated with all the red tape and bureaucracy that went on during this pivotal period in history, and soon gave up on getting his new company off of the ground.• Quisumbing, who was educated at the University of Chicago, came up with a special formula that dried very rapidly on the page, while still remaining fluid inside of the writing instrument.

This Filipino scientist did not rest on his laurels; he went on to write research papers on a diverse range of scientific topics that also related to agriculture, medicinal plants, orchids, and general botany. Always inquisitive and inventive, this scientist would study the plants and flowers of his native country, perform experiments, and draw conclusions designed to inform others. Often, the hypotheses and ideas of Quisumbing were used to improve life for citizens of this southeast Asian archipelago locale.

Doctor Alfredo Santos is a noted researcher in the chemistry of natural products, in particular the isolation and elucidation of the phaeantharine and other alkaloids from Philippine medical plants.

Filipino Chemist - Dr. Alfredo SantosStarting off his illustrious career as a professor of industrial pharmacy within the University of the Philippines, Dr. Alfredo Santos is most known for his research isolating alkaloids from various medicinal plants that are native to the Philippines. The ultimate goal of his research was to help lower the prices of pharmaceuticals, by finding natural alternatives that could perform as substitutes to the sometimes overly pricy imported materials that were so popular at the time. Many people in the countryside couldn't afford those imported drugs, and so there was a high need for these lower-priced alternatives that he helped champion.

An engineer named Daniel Dingel, who used to work for NASA, has developed a car that uses plain tap water and/or sea water for fuel. The technology utilizes a mini-reactor in the car that splits the water molecule into hydrogen & oxygen, with hydrogen being burned off as fuel.The emission released out of the exhaust is clean pure water vapor or water- absolutely no pollution, in fact, it cleans the air. He now has 6 cars running on water, the first car drove out in 1969, over 30 years ago. We have a 15 minute video of a Dingel interview, test drive and engine demonstration of one of his water-fueled cars that we wish to show you. (See end of letter on how to obtain the video). He also has various other water-powered inventions- all are patents pending.

Bienvenido O. Juliano – is a National Scientist who focused on the properties of starch and protein in relation to rice grain quality. He is one of the 1964 TOYM Awardees for Science. He was in charge of grain quality research at the International Rice Research Institute from 1961-1993 and contributed much to the basic knowledge in differences between varieties of grain quality of rice. He showed that any lose content of starch is the key determinant of eating quality of milled rice in Asia and extremely negatively connected with stickiness of cooked rice.

The study of rice grain quality has been the primary focus of the work that Dr. Bienvenido O. Juliano has worked on throughout his career. That includes extensive research into the properties of protein, starch, and other particles that make up a grain of rice. Through Dr. Juliano's efforts, scientists are able to measure potential grain quality as a genetic quality, and thus save time and effort in rice production. That has changed breeding strategies adopted on an international level, and has made rice not only more economically viable for breeders and farmers, but also richer in nutrients. By stripping each variety of rice grain down to its essential components, he has been able to pinpoint what the value is of each variety and combine them to create a more fully enriched and valuable end source of food for human consumption.
