Biography of Dmitri Mendeleev: the father of the periodic table

Biography of Dmitri Mendeleev: the father of the periodic table

From his humble origins in Siberia to his immense contribution to chemistry and science in general, Dmitri Mendeleev stands as an iconic figure in the world of chemistry and scientific research.

Dmitri Mendeleev is known primarily for his decisive contribution to the evolution of the periodic table . However, in addition to the periodic table he made important contributions and scientific research.

This article will explore the life and contributions of this visionary scientist, focusing on his role in the creation of the periodic table and his other notable contributions.

Biography of Dmitri Mendeleev

Dmitri Ivanovich Mendeleev was born on February 8, 1834, in Tobolsk, Siberia, Russia.

His childhood was marked by adversity, as his father died early and his mother had to fight to support the family. Despite these difficulties, Mendeleev showed a great interest in mathematics and science from an early age.

Throughout his life, Mendeleev received numerous honors, including membership in the St. Petersburg Academy of Sciences and the Order of Saint Stanislaus. His legacy lives on in modern science and science education, and his Periodic Table remains an essential tool in the study of chemistry.

The periodic table: Its greatest legacy

Biography of Dmitri Mendeleev: the father of the periodic tableMendeleev's most notable achievement is, without a doubt, the creation of the periodic table of elements. In 1869, he published his seminal work, "Principles of Chemistry", in which he introduced this revolutionary table.

The periodic table organized known elements based on their chemical properties and atomic masses, but most astonishing was its ability to predict the existence and properties of elements not yet discovered.

The empty spaces he left in the table were later filled with elements such as gallium and germanium, confirming the accuracy of his predictions and cementing his place in the history of chemistry.

Scientific contributions beyond the periodic table

Although the periodic table is his best-known legacy, Mendeleev also made important contributions in other fields of science:

His research in thermodynamics laid the foundations for a better understanding of the behavior of gases and chemical reactions.

Science education

In addition to his research, Mendeleev stood out as an educator. He taught at several academic institutions in Russia and wrote influential textbooks that trained a new generation of chemists. His focus on teaching based on sound principles continues to influence science education.

Geological exploration and more

Mendeleev's curiosity was not limited to chemistry. He also ventured into geology, undertaking expeditions in Siberia and contributing to knowledge about mineral formation and regional geology.

In addition, he showed interest in meteorology and applied physics.


In conclusion, Dmitri Mendeleev is a colossal figure in the history of science, whose work transcends chemistry and encompasses multiple scientific fields.

His creation of the Periodic Table of Elements has been fundamental to the understanding of modern chemistry, but his contributions in thermodynamics, solution chemistry, and science education have also left an indelible mark on the world of science.

Mendeleev is a timeless example of the passion, curiosity and dedication that define a visionary scientist.
