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 equilibria
and 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 Ferme
Générale 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 Adolphe
Wurtz's private laboratory at the Faculty of
Medicine in Paris (now the University of Paris
V: René Descartes).

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.

14. LOCAL CHEMISTS

15. Filipino Chemist - Dr. Julian Banzon
The 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.

16. 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.

He discovered that Potassium Nitrate can induce flowering in
Carabao Mangos. He discovered this mango flower induction
by KNO3 in the early 70's, and the technology is now used in
many other countries. Locally it has elevated mango
agriculture from virtual neglect to the Philippine number two
export after bananas.

18. Filipino Chemist - Dr. Alfredo Santos
Starting 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.

purpose, to help advance the field of Philippine science.

21. Filipino Chemist - Evelyn Mae T. Mendoza
The work of Evelyn Mae T. Mendoza is well known, as she was
recognized for her research in the field of plant biochemistry.
That includes the chemicals and biology of the coconut plants,
and various factors that affect the mung bean. Her work with
mung beans was meant to help analyze the nutritional factors
and worth of the plant, for a higher level of nutrition for the
public. This also helped with breeding, planting techniques,
and a wide variety of other factors that affected the
agricultural world, to help make plants grow better and
improve their economical worth in the long run.
She was recognized because of her continuous basic studies in
plant biochemistry particularly, one the biochemical basis of
the makapuno phenotype of coconut; on the factors affecting
the nutritional worth and suitability of cowpea, mungbean
and numerous under utilized Philippine indigenous legumes,
cassava and sweet potato; and on the biochemical source of
resistance of preferred plants to pest or illness.

22. Doctor Lourdes Cruz has made scientific contributions to the
biochemistry field of conotoxins, in particular the toxins of the
venom of the marine snail Conus geographus. Lourdes Cruz
documented the biochemical characterization of the
homologous highly toxic monomeric peptides with internal
disulfide bonds including: Conotoxin GI, Conotoxin GIA and
Conotoxin GII. Lourdes Cruz has helped develop conotoxins for
the purpose biochemical probes for examining the activities of
the human brain.
a biochemist whose research has contributed to the
understanding of the biochemistry of toxic peptides from the
venom of fish-hunting Conus marine snails. The characterization
of over 50 biologically active peptides from the snail's venom
had been made possible, in part, by her studies. She also
contributed to the development of conotoxins as tools for
examining the activity of the human brain. For instance, w-conotoxin
is widely used for studying neutral calcium
channels and m-conotoxin is used when muscular activity must
be controlled to examine events at the synapse. Dr. Cruz'
scientific awards include: the NAST Outstanding Young Scientist
Award,1981; the NRCP Achievement Award in Chemistry, 1982;
and the Outstanding Women in the Nation's Services Award
(Bio-chemistry).

23. After obtaining his Ph.D. with straight A's at the age of 22, Dr,
Juliano consistently demonstrated excellence in research. at
age of 42, he ha already more than a hundred scientific
articles mostly published in international journals.
Dr.Juliano is known for his researches in nuclear chemistry and
physics. Noteworthy of his published research works with total
50 are (1) Rapid and Non-destructive Analysis of Sulfur and
Calcium by Radio activation and Photo neutron Counting,
Dr. Jose Juliano, born on
October 16, 1932
is famous for researches in nuclear chemistry and physics. In
1959, hewas one of the receivers of the TONYM award
for hisinvolvement in Nuclear Science. He is also an affiliate of
the American Nuclear Society, American Physical Society and
the American Chemical Society.
His contributions have helped manage better understanding of
nuclear science. He was remarkable of his in print research
works with total 50 are Rapid and Non-destructive Analysis of

Counting and Disintegration of Iron-52 and Iron-53.

24. 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.
