Short Summary
Dmitri Mendeleev was a Russian chemist and inventor best known for creating the Periodic Table of Elements. His groundbreaking work in classifying elements according to their atomic weights laid the foundation for modern chemistry. Mendeleev's periodic law and his ability to predict the properties of undiscovered elements significantly advanced the scientific community's understanding of chemical behavior. His contributions have made him one of the most renowned figures in the field of chemistry.
Early Life & Education
Dmitri Ivanovich Mendeleev was born on February 8, 1834, in Tobolsk, Siberia, Russia. He was the youngest of 17 siblings in a family that valued education. His father was a teacher, and his mother managed a glass factory. After his father's early death and the destruction of the factory by fire, the family faced financial difficulties. Mendeleev's mother moved the family to St. Petersburg to provide him with better educational opportunities. He attended the Main Pedagogical Institute, where he developed a keen interest in chemistry, particularly under the mentorship of renowned chemists like Alexander Voskresensky.
Career Highlights
Mendeleev's career flourished at the St. Petersburg University, where he became a professor of chemistry. His most significant contribution was the formulation of the Periodic Table in 1869, which organized elements based on their atomic weights and properties. He also published the textbook "Principles of Chemistry," which became a standard reference in the field. Mendeleev's predictions of the properties of elements not yet discovered were remarkable for their accuracy. His work extended beyond chemistry; he made contributions to the fields of physics and meteorology.
