He was born in the village of Verkhnie Aremzyani, near Tobolsk in Siberia. Raised as an orthodox Christian, Dmitri’s mother used to encourage him to search divine and scientific truths. He later went on to inform his family that he has departed from the Church to embrace deism. Dmitri’s father was a teacher of fine arts, politics, and philosophy however due an unfortunate turn of events, his father lost his eyesight and had to eventually stop teaching. His mother was forced to work, and she restarted her family’s abandoned glass factory to support the family. After the death of his father, Dmitri went on to attend the Gymnasium (a school providing advanced secondary education with strong emphasis on academic leaning) in Tobolsk.

Dmitri investigated the composition of petroleum and helped find the first oil refinery in Russia. In 1905 he was elected as the member of the Royal Swedish Academy of Sciences. This led to the Nobel Committee for Chemistry recommending the Swedish Academy to award him the Nobel Prize in Chemistry the following year, i.e. 1906 for his discovery of the periodic system. The chemistry section of the Swedish Academy supported this recommendation. However due to the influence of Svante Arrhenius, who was fueled by a personal grudge, the award was given to Henri Moissian. In 1907, Dmitri died at the age of 72 in Saint Petersburg. The crater Mendeleev on the Moon, as well as the element number 101, the radioactive mendelevium, is named after him.
