Engineer Valentin Petrovich Vologdin created over a hundred different inventions during his lifetime. He admitted that from a young age he was inspired by Alexander Popov: "the information about Popov's work amazed my imagination, especially considering that Popov was my fellow countryman, a Ural native, and this determined my further technical career." In 1907, Vologdin graduated from the St. Petersburg Technological Institute and then began working at the factory "Glebov and Co," which specialized in the production of electromechanical equipment and collaborated with the Navy.

At that time, radio communication was the only means of wireless communication in the Russian fleet. However, most devices were purchased abroad and were of poor quality: they operated with interference, had low power, and often broke down. It was necessary to create domestic radio stations, and Vologdin took on this challenging project. He carefully studied foreign devices, immersed himself in scientific literature, and through trial and error developed a powerful radio generator. Now the signal between ships reached a radius of 5 km.

The peak of Valentin Petrovich's career came during World War I, when orders from the military department came one after another. Vologdin, in particular, designed an onboard generator for the famous bombers "Ilya Muromets." Since 1915, he actively worked on modernizing equipment for coastal radio stations. English and French specialists recognized his inventions as the best in the world.

After the October Revolution of 1917, Vologdin was offered to move to England and work for their military-industrial complex, but he refused, believing that his knowledge was more needed by his homeland. He later engaged in the development of radio telephony and created a high-voltage rectifier for powering complex tube radio stations. One of his last projects was the development of the theory of high-frequency hardening, which reduced the thermal treatment of metal parts from 30 hours to 40 seconds. Vologdin passed away at the age of 72 in Leningrad.
