The house of “P.A. Ovchinnikov ”according to its significance and value estimates is included in the first category of jewelers and gold and silver enterprises of pre-revolutionary Russia. As a master of silver, in 1851 Pavel Akimovich OVCHINNIKOV (June 23, 1830 - April 7, 1888) opens in Moscow, what later became the world-famous company producing gold and silver products. Repeatedly, the company was the executor of large government orders for the imperial court, and from the first year of its existence it was famous for its work. Since 1865, the company becomes a full-time supplier of the court of Tsarevich Alexander (the future Emperor Alexander III) and receives the highest status of “court”. In 1872, the enterprise was awarded the title of supplier of the courtyard of His Imperial Majesty, in 1878 - the title of supplier of the courtyard of Grand Duke Mikhail Nikolaevich. In 1881 and 1896, the status of the court supplier was confirmed. Ovchinnikov factory was a trendsetter in jewelry fashion and was considered, from the point of view of the organization, the largest trade and production enterprise of that time. The production department of the Ovchinnikov firm was located in Moscow on the Goncharnaia street in the house of Lezhnev and Biryukova. The trading divisions of the company in Moscow are represented by shops on the Kuznetsk bridge (Vargin's house) and Ilyinka (Khludov's house). In addition to its own stores, Ovchinnikov's company placed its orders in trading houses. For example, the company’s cooperation with the Beilin & Son trading house is well known. Trading houses, being a historical feature of the organization of jewelry production in the late XIX and early XX centuries, had significant working capital and had the opportunity to wholesale large quantities of various gold and silver products from craftsmen and firms and then sell them at relatively low prices. The company had numerous awards and titles, not only domestic, but also many overseas from imperial, royal and princely houses. In 1917, due to a radically changed political situation, following most of the enterprises of tsarist Russia, Ovchinnikov’s company with all production, trade and training departments ceased operations.
