The House of Demidov (Russian: Деми́довы) also Demidoff and Dimidov, was a prominent Russian noble family during the 18th and 19th centuries. Originating in the city of Tula in the 17th century, the Demidovs found success through metal products, and were entered into the European nobility by Peter the Great. Their descendants became among the most influential merchants and earliest industrialists in the Russian Empire. At their peak, they were estimated to have had a net worth of around $300 billion and to be the second-richest family in Russia, behind only the Russian Imperial Family. The Demidov family scattered to America and to Italy and other European countries as a result of the February Revolution of 1917.
