These items belonged to Yevgeny Grigorievich Voropayev. He was born in Tula in 1931. Together with his parents, he was evacuated to the Urals during the Great Patriotic War. In his memoirs, he described how the Tula Plant was operating during the evacuation.

He wrote,

Yevgeny Voropayev noted that there were food supply chain failures; every person was entitled to 400 grams of bread due to food rationing. “1,200 children were evacuated along with us. A vocational school was organized for them to train them as middle-level specialists: locksmiths and turners. At first, these children did not know any skills. They were simply given a hammer and nails, and allowed to use them, as they couldn’t yet be taught anything more complex. Therefore, the establishment of this vocational school could serve their intellectual development only when they were grown enough to understand things. Experts in electrical engineering, plumbing, mechanics of materials, manufacturing equipment, and heat engineering taught there.”

In 1944, Yevgeny Voropayev entered the vocational school at the Tula Arms Plant in Mednogorsk. He also graduated from a technical school there. After the war, in 1954, he graduated from the Ural Polytechnic Institute and was assigned to work at the Tula Combine Plant. Then he worked in the trust “Tulspetsstroy”, the directorate of the Tula State Farm, and the trust “Tuluglestroy”.

In 1961, he was elected to the position of associate professor of the Department of Electrical Engineering of the Tula Mechanical Institute; in 1962 he became head of the department. In 1969, Yevgeny Voropayev defended his doctoral thesis, and in the same year he received the title of associate professor. Voropayev was awarded the medals “For Valiant Labor in the Great Patriotic War”, “50 years of Victory in the Great Patriotic War”, and “Veteran of Labor”, as well as three silver medals of the Exhibition of Achievements of National Economy of the USSR.
