Famous chemist and their contributions

Famous chemist and their contributions made a difference to the science community and also to the world. Without, the chemist’s contributions we wouldn’t have a better understanding of how things work in general related to science. In fact, chemistry is all around us, whether it’s in our home, in the environment, in medication, or even in the food we eat. Here are four notable chemists that had made discoveries in various fields of chemistry. There are:-

1.  Louis Pasteur
2. Frederick Sanger
3. John Dalton
4. Ira Remsen

Famous Chemists in History

Louis Pasteur was a famous chemist and their contributions was greatly acknowledged to the work done in the science community. Louis Pasteur was born in Dole, a small town in eastern France. Before Louis Pasteur became a scientist, he had shown talent as an artist. But in high school he became more interest in scientific subjects. He completed his bachelor of Science Degree at the Besancon College Royal de la Franche with honors in physics, mathematics, and Latin. Then he moved on to the Ecole Normale Superieure in Paris to study physics and chemistry.

He then when on and got his Doctorial Degree . Although, Louis Pasteur  was a French Chemist and a microbiologist. He was also a professor in physics and chemistry. Louis Pasteur conducted various experiments . These experiments are :- He was the first person to create a vaccine in the 1860s called the germ theory of disease. The development of this vaccine led to the vaccination for anthrax, rabies, and Foul cholera. When Louis Pasteur was developing the germ theory, he also proved that food spoiled because of contamination by ideal bacteria and not because of spontaneous generation.

Modern Chemists

Frederick Sanger was a modern and a  famous chemist and their contributions assist in the chemical and biological world.  Frederick Sanger was a biochemist. He won the Nobel Prize in chemistry twice. The first Nobel Prize was in 1958.  He won it for his work on the structure of insulin which is a protein.

Sanger started working on this experiment in 1953. When he was at Cambridge University in England. This is where he reported the amino acid sequence of the two polypeptide chains.  That compose the protein insulin which is call the bovine insulin structure. His results show that all of the molecules of a given protein have a fixed amino acid composition, a defined amino acid sequence, and unchanged molecular weight. His works make it possible for other chemists to identify the exact structure of other compounds.

The second Nobel Prize he won was in 1980. Sanger had shared his prized with Walter Gilbert, for their contributions concerning the determination of based sequences in nucleic acids, and Paul Berg for his work on recombinant DNA. Sanger was one of the two scientists, who assisted in one of the two techniques which made the sequencing of the Sanger method.

This method makes use of the mechanism of DNA by DNA polymerase.

Famous Chemists

Robert Boyle was a famous chemist and their contributions  in today chemistry  world . In fact Boyle equation is used every day in chemistry by students, professors and scientists . Robert Boyle was an Anglo-Irish natural philosopher and theological writer. He was best known as a natural philosopher and he was sometimes called ” the father of modern chemistry.” But in his scientific work, he mainly covered areas including hydrostatic, physics, medicine, earth sciences, natural history, and alchemy.

Boyle was very involved in philosophers formed the ” Experimental philosophy club”. Boyle’s first scientific publication was “New Experiments Physico-Mechanicall, Touching The Spring of the Air and Its Effects in 1660” . This experiment was done by Boyle and Robert Hooke. This is where there resulted in discoveries regarding air pressure and vacuum. They also discovered several physical characteristics of air, including its roles in combustion, respiration, and the transmission of sound.

In 1662, he had published the second version of the experiment he and Hooke had published in 1660. This is where he described the inverse relationship between pressure and volume , which is known as Boyle’s law. Boyle’s Law is a gas law that stated the pressure exerted by a gas is inversely proportional to the volume occupied by it. This is providing the temperature remains unchanged within a closed system.

Top 100 Chemists

Ira Remsen was born in New York city in the USA to Dutch parents. He is one of the top 100 hundred chemists. Remsen had excelled in the classics. He had no formal training or exposure to science in his early years of school. Although he entered college early, he never finished the 4 years of education. Instead, he was an apprentice to a doctor who taught in homeopathic medical school. He was later permitted to enroll at the College of Physicians and Surgeons at Columbia University in 1867.

Instead of practicing medicine, he decided to study chemistry in Munich and Gottingen which is located in Germany. In 1870, he received his Ph.D. in chemistry from the University of Gottingen. After he received his Ph.D., he began his investigations in pure chemistry at the University of Tubingen where he became a professor for chemistry and physics at Williams College. Ramsen was an author, therefore he had published the popular textbook name ” Principles of Theoretical Chemistry” in 1876. For 35 years, he edited the American Chemical Journal which he found in 1879.

Ramsen, along with his student on Contantine Fahbery, had accidentally discovered the artificial sweetener in the year 1879. This occur in the laboratory of Remsen at John Hopkins University, in Baltimore USA. Another name for artificial sweetener is Saccharin. This occurred when Remsen and his student were working on coal tar derivatives benzoic sulfimide. Remsen and his student soon after developed a synthesis of saccharin from 0-sulfamoylbenzoic acid.

They eventually published their findings in 1880. Unfortunately, in the mid-1880s Fahlbery began to manufacture saccharin in Germany without Gemsen’s knowledge. Which led to the fallout between the partnership.

Conclusion

In Conclusion, these four famous chemists I mention along with other famous chemists made great contribution to science field especially the chemistry field .So we can have a greater understanding what is really happening around us.
