Dmitri Mendeleev [SEP] Early life
Mendeleev was born in the village of Verkhnie Aremzyani, near Tobolsk in Siberia, to Ivan Pavlovich Mendeleev (1783–1847) and Maria Dmitrievna Mendeleeva (née Kornilieva) (1793–1850). Ivan worked as a school principal and a teacher of fine arts, politics and philosophy at the Tambov and Saratov gymnasiums. Ivan's father, Pavel Maximovich Sokolov, was a Russian Orthodox priest from the Tver region. As per the tradition of priests of that time, Pavel's children were given new family names while attending the theological seminary, with Ivan getting the family name Mendeleev after the name of a local landlord. Maria Kornilieva came from a well-known family of Tobolsk merchants, founders of the first Siberian printing house who traced their ancestry to Yakov Korniliev, a 17th-century posad man turned a wealthy merchant.
