Alexander Ferdinandovich Kelch was a Russian nobleman who lived in St Petersburg at the end of the nineteenth century. He is now known mainly as a patron of Fabergé, having commissioned seven eggs for his wife Barbara.
His wealth came from marrying his brother's widow Varvara Petrovna Bazanova, whose family had made a fortune in Siberian industry, particularly gold-mining. The Bazanov business empire collapsed after the Russo-Japanese War; the couple divorced in 1915, Varvara moving to Paris and Alexander remaining as a pauper in Russia; he was arrested and disappeared in Siberia in 1930.
