Transcript of Dmitri Mendeleev
In 1867, Mendeleev begins teaching general chemistry at the University of St. Petersburg.
While he was teaching, he realized the necessity of structure and organization when it came to inorganic chemistry.
Mendeleev, along with many other scientists, believed that the answer lay in the ordering of the atomic weights of elements.
Awards & Achievements
In 1856, Mendeleev was awarded his M.A. degree followed by his Ph.D. from the University of St. Petersburg.
In 1861, at the age of 27, Mendeleev published his book Organic Chemistry, which won the Domidov Prize.
He won a Nobel Prize in Chemistry.
In 1906, Mendeleev was selected by the prize committee to win the honor, but the Royal Swedish Acadamy of Sciences stepped in and overturned the decision. The intervention was led by swedish chemist Svante Arrhenius, who had one the prize in 1903 for his theory of electrolytic dissociation. Mendeleev had been an outspoken critic of the theory, and Arrhenius seized the opportunity to get back at Mendeleev.
Cultural/ Real Life Connections
Dmitri Mendeleev revolutionized our understanding of the properties of elements and their atoms and provided the world with a efficient, organized table of the elements that is still used today.
At the age of 72, Dmitri Mendeleev died on February 2, 1907 of pneumonia.
Mendeleev's determination and success in creating The Periodic Table has immensely benefited the entire the study of, not only chemistry, but science as a whole. Whether it is physics, engineering, biology, geology, medicine, or in industry.
At a young age, he excelled in math and physics.
His mother saw this and was determined to provide him with the best education possible.
Marya then went on to St. Petersburg and enrolled Dmitri at the Chief Pedagogical Institute, where his father had once attended.
He got accepted on a full scholarship.
That same year, his mother died at the age of 16 and Dmitri was orphaned.
In 1847, Dmitri's father went blind and couldn't work any longer, which meant his mother had to help to support the family, and she did by opening a glass factory.
In 1848, the glass factory burned down, which is the same year that Dmitri's father died.
At this point, the only family members still living in the house were Dmitri, his mother Marya, and his sister.
His mother went to her wealthy brother in Moscow in the hope that he would help her son Dmitri receive quality education. He refused to help her.
During his third year of studies at St. Petersburg, Dmitri became very ill and was confined in bed for a lengthy amount of time.
In 1863, Mendeleev married Feozva Leshcheva and had two children. A son named Volodya and a daughter named Olga after his sister.
Ultimately, the marriage was unsuccessful, and the two separated.
In 1882, he married his niece's best friend, Anna Popova nad had four more children.

Cultural/Real Life Connections
Dmitri Mendeleev was born in Tobolsk, Siberia on February 8th, 1834.
He was the youngest of his family and he had had 16 siblings.
Mendeleev stated the Periodic Law, which states that many of the physical and chemical properties of the elements tend to reoccur in a systematic manner with increasing atomic number.
Much of his research also dealt with agricultural chemistry, oil refining, and mineral recovery. He was a founding member of the Russian Chemical Society.

The Periodic Table
Mendeleev arranged the elements in a sequence of increasing weights. He noticed that the chemical properties of the elements were grouped into familiar families already.
Sometimes he would leave a blank space in order to predict the properties of unknown elements that would fill in the blank area. During his life time, these elements were identifies and found to have very similar properties to those Mendeleev predicted, thus establishing the authenticity of the periodic table.
