He was a son of the wealthy merchant and industrialist Ivan Feodorovich Mamontov and Maria Tikhonovna. In 1841, the family moved to Moscow. From 1852, he studied in St. Petersburg, and later at the Moscow University. In 1862 his father sent him to Baku to engage in business with the elder Mamontov's Trans-Caspian Trade Partnership. In 1864, Savva visited Italy where he began to take lessons in singing. There he was introduced to the daughter of Moscow merchant Grigory Sapozhnikov, 17-year-old Elizabeth, who subsequently became his wife. The wedding took place in 1865 at the Kireevo estate, near Khimki, just northwest of Moscow. Upon his father's death in 1869, he succeeded to his share in the Moscow-Yaroslavl Railway, and at the recommendation of his father's friend, Fedor Vasilyevich Chizhov, he was elected a director of the company. In 1872 he was elected its chairman. The extension of the railway from Sergyev Posad to Yaroslavl, begun in 1868, was opened for traffic on 18 February 1870. A narrow-gauge branch from Uroch station to Vologda was opened on 20 June 1872, followed by the Alexandrov-Karabanovo branch in 1877 and the Yaroslavl-Kostroma line in 1887. Mamontov also supervised the construction of the Donets Coal Railway, which connected a network of sparsely populated mining villages with the port of Mariupol, between 1875 and 1878. The Moscow-Yaroslavl system was greatly expanded in the 1890s. The Yeremoino-Sereda line was opened in 1893, followed by Mytishchi-Shchyolkovo line in 1895. Also in 1895, the railway purchased the Shuysko-Ivanovskay and Yermolino-Seredskaya lines from the Shuysko-Ivanovskaya Railway. In 1896 the Alexandrov-Kirzhach and Belkovo-Yuryev-Polsky-Ivanovo-Teykovo lines were opened, followed by the Nerekhta-Sereda line in 1898. The biggested expansion, especially in terms of future importance, was the construction of the Yaroslavl-Archangelsk line between 1894 and 1897. It was formally opened on 17 November 1897, although difficulties with the swampy ground delayed full service on the line till 1898.
Mamontov's world came crashing down when, in 1899, an audit revealed that his factories had been improved since 1890 with funds from the railway, a course of action that was contrary to law. He was compelled to resign as chairman of the railway on 30 July 1899. Unable to pay his creditors, he began to sell off assets to raise funds, but this course was brought to an abrupt end on 11 September 1899 when he was arrested and lodged in the Tagansky prison in Moscow. Mamontov was unjustly accused of embezzlement; he was released from custody early in 1900, and at his trial in June 1900, defended by F.N. Plevako, he was acquitted. Acquittal did not avert his financial ruin, for on 7 July 1900 he was declared insolvent by the Moscow District Court, and his property was sold at public auction. Savva Ivanovich Mamontov died in Abramtsevo after a long illness on 6 April 1918.
Quotations
"I was a rich man, that's true, but I gave up everything since I believed that money is for the people and not people for the money. Who needs money when there is no life?" '
"Contemporaries called Savva Mamontov "Savva the Magnificent" likening him to Duke Lorenzo de' Medici who was known as Lorenzo the Magnificent. But Savva Mamontov was more than a patron of arts and letters, he was a businessman as well, and his contribution to both the national economy and the arts was equally great." '
