Significant Milestones in Chemistry: A Timeline of Influential Chemists

Author: Vera KoesterORCID iD

Throughout history, countless chemists have made groundbreaking discoveries and contributed to our collective knowledge. In this article, we will take a journey through time and explore some of the most significant milestones in the field of chemistry. Starting from the early alchemists, we will examine how each of them pushed the boundaries of what is possible. By the end of this timeline, you will have a deeper appreciation for the contributions of these chemists and the impact they have had on the world around us and how chemistry evolved throughout the centuries.

Since we cannot list every outstanding chemist, we limit ourselves to those for whom we have already published an article in ChemistryViews.

 

 

Alchemy, an ancient branch of natural philosophy, studied substance properties and reactions since the 1st/2nd century. It was a proto-scientific tradition in China, India, the Muslim world, and Europe. Modern chemistry and pharmacology replaced it during the 17th and 18th centuries.

 

1600 

   
 

During the Renaissance and 17th century, the scientific method—emphasizing the importance of observation and experimentation in gaining knowledge about the world—was developed and refined, leading to the foundation of modern chemistry and other scientific disciplines. Discoveries of gases, improvements in alchemy, advancements in metal production, and developments in chemistry’s role in medicine were also made during this period.

1700 

   
 

In the 18th century, new gases such as hydrogen, carbon dioxide, and nitrogen were discovered, and the phlogiston theory was widely accepted but later proven incorrect. New elements were discovered, and Antoine Lavoisier introduced a new system of chemical nomenclature. Additionally, chemical instrumentation such as the balance, calorimeter, and spectroscope were developed for analysis and measurement.

In the 19th century, John Dalton proposed his atomic theory, which laid the foundation for understanding atoms and chemical reactions. Organic chemistry was born, with Friedrich Wöhler’s synthesis of urea challenging the theory of vitalism. Dmitri Mendeleev’s periodic table organized elements by their properties, while electrochemistry made progress with the discovery of electrolysis and batteries. Finally, thermodynamics developed as a branch of chemistry with contributions from Rudolf Clausius and James Clerk Maxwell.

    Accept my congratulations for this remarkable illustration of remarkable chemists.
    My minor comment: there are indications that the idea of cyclic structure to benzene (Bull. Sor. Chim. Paris, 3, 98-110, 1865) originated from a book by Loschmidt (Chemische Studien, 1961).
