The Evolution of Organic Chemistry: From Ancient Practices to Modern Science

The history of organic chemistry is a remarkable story of human curiosity and discovery, tracing how our understanding of the substances that make up life has evolved from ancient times to the present day. From early chemical experiments in antiquity to the development of powerful modern tools like spectroscopy and molecular modeling, organic chemistry has shaped countless advances in science, medicine, and industry.

The foundations of organic chemistry can be traced back to ancient civilizations. Around 3000 BCE, the Egyptians practiced distillation to produce perfumes and essential oils—early examples of chemical manipulation of organic substances. By the 4th century BCE, Greek philosophers like Aristotle speculated that living organisms contained a special “vital force” that distinguished them from nonliving matter. This idea, known as vitalism, would dominate scientific thought for nearly two thousand years. During the Islamic Golden Age around 800 CE, alchemists refined laboratory techniques, developing apparatus such as the alembic and improving processes like crystallization and distillation. These innovations laid the groundwork for the later emergence of modern chemistry.

A major shift occurred in the 17th century when Robert Boyle, often called the father of modern chemistry, rejected alchemy and proposed that all matter consists of elements that combine in fixed proportions. In 1746, John Roebuck developed the first industrial-scale synthesis of sulfuric acid, a compound essential to many organic reactions. These early developments signaled a move toward systematic experimentation and analysis.

The 19th century marked the true birth of organic chemistry as a scientific discipline. In 1806, Swedish chemist Jöns Jacob Berzelius coined the term “organic chemistry” to describe compounds derived from living organisms. However, the field transformed dramatically in 1828 when Friedrich Wöhler synthesized urea—an organic compound found in urine—using inorganic ammonium cyanate. This achievement, known as the Wöhler synthesis, disproved the long-held theory of vitalism and demonstrated that organic compounds could be created from nonliving materials.

Following Wöhler’s discovery, chemists such as August Kekulé and Archibald Scott Couper advanced the concept of carbon’s tetravalence, explaining how atoms bond to form complex molecules. In 1865, Kekulé proposed the ring structure of benzene, an insight that revolutionized the understanding of aromatic compounds. Soon after, in 1874, Jacobus van ’t Hoff and Joseph-Achille Le Bel introduced the concept of molecular three-dimensionality, explaining why certain compounds exhibit optical activity—an essential principle of modern stereochemistry. Around the same time, William Perkin’s accidental synthesis of mauveine, the first artificial dye, ignited the growth of the chemical industry.

The 20th century brought even greater breakthroughs. In 1907, Leo Baekeland invented Bakelite, the world’s first synthetic plastic, ushering in the age of polymers. Niels Bohr’s 1913 atomic model deepened the theoretical understanding of chemical bonding. Advances such as chromatography (1906) and nuclear magnetic resonance (NMR) spectroscopy (1939) revolutionized the ability to analyze molecular structures. Finally, in 1953, James Watson and Francis Crick—building on Rosalind Franklin’s X-ray data—discovered the double helix structure of DNA, cementing organic chemistry’s central role in biology.

Today, organic chemistry continues to drive innovation in medicine, energy, and materials science. From life-saving pharmaceuticals to biodegradable plastics, the field remains vital to addressing global challenges. Its history, stretching from the mysticism of alchemy to the precision of molecular design, reflects humanity’s enduring quest to understand and shape the living world.

History of Maillard reaction

Louis Camille Maillard was a chemist and physician, who was born in Pont-à Mousson, France, in 1878, and died in Paris in 1936. He began his studies in Nancy, where he obtained the degrees of M. Sc. in 1897 and Dr. Med. in 1903. In 1914 he moved to Pari s and the young doctor worked as head of a biological group in the Chemical Laboratory, University of Paris.

The Maillard reaction, named after L. C. Maillard, is also known as nonenzymatic browning. It is an extremely complex process and is the reaction between reducing sugars and proteins by the impact of heat.

The history of Maillard reactions begins in 1866, when Hugo Schiff (1834-1915) published that aldehydes (including sugars) react with amines (including amino acids) to form dark compounds. He proposed the formation of secondary imines (today called Schiff's bases) from aldehydes and aromatic amines. The reaction between carbonyl compound and primary amine discovered by Hugo Schiff in 1864 gave basis for further research in various scientific fields and resulted in thousands of papers being submitted by scientists all over the world to a diverse spectrum of scientific magazines.

In 1871, R. Sachsse studied the reaction of lactose with aniline, before Emil Fischer investigated the reactions of sugars and amino compounds in 1884 and 1886. Fischer focused on the reactions of D-glucose, D-fructose or sucrose with phenylhydrazine. Maillard was interested in Emil Fischer’s synthesis of peptides, which he thought, correctly as it turned out, could be achieved under milder conditions by the use of glycerol.

In 1909, Maillard began his studies. They are summarized in his 1913 academic report, under the title "Genèse des matières protéiques et des matières humiques”. He wrote at least eight related papers, with findings including carbon dioxide release as amino acids broke down, and the formation of a brown pigment.

He observed the formation of yellow-brown pigments in the reaction among sugars and amino acids, polypeptides, or proteins; and among polysaccharides and polypeptides, or proteins, in a heated solution.

Maillard searched for milder conditions. Thus, he wished to condense amino acids by use of glycerol as a condensing agent. He thus obtained cycloglycylglycine and pentaglycylglycine. Then, he used sugars instead of glycerol to investigate the formation of polypeptides from amino acids.

It was found that the aldehyde group (of an aldose) had more intense effect on amino acids than did the hydroxyl groups. This led to the discovery of the browning reaction, which is now more commonly known as the Maillard reaction.

At first, combining amino acids and sugars was simply called browning, and scientists only started calling it the Maillard reaction around 1947. In 1953, the US Department of Agriculture’s John Hodge proposed detailed mechanisms, breaking the Maillard reaction into three steps: the early Maillard reaction, the advanced Maillard reaction, and final Maillard reaction.

Raoult’s Law

Raoult’s Law is named for François-Marie Raoult (10 May 1830 – 1 April 1901) a French chemist who was one of the founders of physical chemistry.  He gave an important law about vapor pressure of the solution, known as Raoult’s law.

He observed experimentally that - in liquid-vapor phase equilibrium of a mixture - the partial pressure of a vapor constituent is proportional to the mole fraction of that constituent in the solution.

Raoult also investigated freezing point depression of solvents when a small amount of solute is introduced. In 1882, Raoult published his results on the effects of nondissociating organic solutes, from which he deduced a general law controlling the lowering of freezing points. Four years later he extended this work to show the effect of solutes on a vapor pressure.

Raoult’s Law is strictly applicable to ideal liquid solutions at all compositions, pressures and temperatures. In an ideal of perfect solution, the components are mutually miscible in all proportions and there are no volume or thermal changes on mixing.

Raoult published the formulations of his laws in the Comptes rendus for 1882 and 1887.

Henry’s Law of Gases by Dr William Henry

In 1805, an English Chemist William Henry (1774-1836) have an important generalization called Henry’s Law on the basis of series of observation about the quantitative affect of pressure on the solubility of gases.

Henry entered Edinburgh University in 1795, received his MD in 1807 and later specialized in urinary disease. Henry worked as a physician at the Manchester Infirmary, studying bladder stones and writing an essay on diabetes. He drifted to chemistry taking over a chemical works established by his father.

Henry devoted much of his research time to chemistry, with an emphasis on the behavior of gases.  He read one of his best-papers to the Royal Society in 1802 and published it in 1803: Philosophical Transactions of the Royal Society.

The paper describes experiments on the quantity of gases absorbed by water at different temperatures and under different pressures

This led to Henry’s Law of Gases. The Henry law states that the solubility of a gas at a given temperature is directly proportional to the pressure at which it is dissolved.

Discovery of resveratrol

The history of resveratrol, the active ingredient in red grapes, peanuts, berries, and several other food plants, indirectly dates to the Ayurveda, the ancient India treatise on the science of longevity.

Resveratrol was first isolated by Takaoka in the 1940 as a constituent of the roots of white hellebore.

Later, Nonomura isolated resveratrol from Japanese knotweed of Polygonum cuspidatum, called Ko-jo-kon in Japanese in 1963.

In 1992, the presence of resveratrol was reported in red wines and recognized as a biological active compound by Siemann and Creasy.  A number of epidemiological studies suggested that the moderate consumption of red wine by French and other Mediterranean population was connected with the reduced incidence of cardiovascular disease, despite high-fat diet, little exercise and widespread smoking.

The groups of Howitz and Sinclair from Harvard Medical School reported in 2003 in the journal Nature that resveratrol significantly extends the lifespan of the yeast Saccharomyces cerevisiae.

Electrophoresis by Arne Tiselius

Arne Wilhelm Kaurin Tiselius (August 10, 1902 – October 29, 1971) firstly described electrophoresis in 1933. It is a technique for the separation of charged molecules.

The Tiselius tube, as it became known, made it practical to study protein mixtures particularly blood proteins.

Tiselius was awarded the 1948 Nobel Prize in chemistry for work with electrophoresis.

Tiselius was from University of Uppsala, Sweden, where he studied under Theodor Svedberg. Tiselius’s doctoral dissertation in 1930 was on the electrophoresis of proteins.

He then published expanded observations using the moving boundary method of electrophoresis in 1937, which led to his 1948 Nobel Prize in chemistry.

This technique was applied by Tiselius to analyze the composition of blood serum. Owing to this method, Tiselius was able to confirm the existence of different groups of protein including albumins, globulins and antibodies.

His technique made it possible for Linus Carl Pauling to demonstrate in 1949 that the sickle cell gene affects the hemoglobin.

History and development of periodic table

The early Greeks thought that all material on Earth was constructed of a combination of four basic elements: earth, water, air and fire.

In the pre-Christian era the ancients knew only seven basic metals: gold (Au), silver (Ag), copper (Cu), lead (Pb), tin (Sn), iron (Fe), and mercury (Hg). Mercury was discovered last, about the 4th century BC.

The ancient knew about sulfur (S), but called it brimstone, and carbon in the form of diamonds and charcoal.

In 1669 a group of German chemists isolated phosphorus the first minerals element to be accurately identified.

On of the next major development, was due to Jeremias Benjamin Richter, who between 1792 and 1794 published a set of quantities that later became known as equivalent weights.

The periodic table was discovered in 1869 by as many as five or six individuals including Russian chemist Dmitri Mendeleev (1834-1907) at about the same times, following the rationalization of atomic weights at the Karlsruhe conference.

The periodic table of the chemical elements is organized as a matrix of rows of horizontal ‘periods’ that list the elements in their increasing atomic numbers and generally, according to their atomic weights.

The table was revised by British physicist Henry Moseley (1887-1915), who came up with the concept of atomic numbers, numbers based on the number of protons (positively charge particles) in an elemental atom.

The periodic table is a clean, crisp way of characterizing the elements, and if anybody are now or ever were a chemistry, physics or premed student, he can testify first hand to the of memorizing the information it provides.
