Alexei Vasilyev served the Turchaninov family since childhood. His origin is unknown. He proved himself a capable salesman and eventually got more important tasks to perform. In 1737 he married the daughter of Michail Turchaninov, Fedosya, and took his wife's surname. He took control of their fortune when he was about 20 years old. He placed high emphasis on metallurgy at the Troitsky Copper Smelting Plant, constantly seeking to improve the product quality. on the coat of arms of Sysert. He supplied high-quality coppercookware to the court and gained favour with the Empress Elizabeth. In 1758 he used his connections at the court and became the owner of the three plants in the Ural region. He was permitted to purchase the Gumyoshevsky mine along with the Polevskoy Copper Smelting Plant, Seversky Pipe Plant and Sysertsky Plant for 145,5 thousand rubles. These factories represented the so-called Sysert Mining District. They were extremely profitable. Turchaninov reorganized the production process and changed the focus from producing metal only to making other products, such as flat iron, roofing iron, household items and so on. The Mining Commission that supervised the plants in 1766 was very satisfied with the result. They said in their report that Turchaninov multiplied the performance capabilities of the plants. Turchaninov engaged in philanthropy. He was known for caring about his workers. He ordered to give away timber, poles, firewood to local populace for free. Once a year the workers had a month's holiday, fully paid. Medicines, health care and schooling were free as well. Turchaninov built the zoo, the botanical garden, two museums, and the library in Sysert. He founded several settlements in the Ural region. He started the mining of malachite and managed to create a high demand for the product. During Pugachev's Rebellion he organized the defences and led the people himself. Turchaninov managed to repel all the attacks by the rebel forces, preventing them from advancing further to Yekaterinburg. Mostly due to these acts of bravery Catherine the Great granted him nobility in 1783. His new coat of arms included "a silver heron holding a stone". The image of a heron was used as a brand of the metallurgical plants in the Sysert Mining District till the 20th century.
