In 1809, at age 14, she married Ivan Pavlovich Mendeleev, a school principal and a teacher of fine arts, politics and philosophy. Maria birthed 17 children, of whom "only 14 stayed alive to be baptized" according to her son Pavel. She encouraged all of her children to read, calling books, "the gift of words on paper". In 1834, the same year that Maria's youngest child,
Dmitri was born, Ivan became blind due to cataracts and unable to work. After Ivan Mendeleev's death from tuberculosis in 1847, the large family lived Maria's income from managing the factory. Later Dmitri would recall: "There, at the glass factory managed by my mother, I received my first impressions of nature, people, and industrial affairs. In 1848, the factory burned down. Maria persisted, and moved with her children to
Saint Petersburg, an arduous 700km trip by horse and cart. ==Legacy==
