A. Lodygin's diving apparatus with a mix of oxygen and hydrogen that he designed in 1871 was the father of the modern diving suit.
In 1837, a Russian inventor D. Zagryazhsky designed a "carriage with mobile tracks" which he patented the same year. In 1879, F. Blinov created the first tracked vehicle.
In 1885, N. Benardos and N. Slavyanov were granted a patent for an electric arc welder with a carbon electrode called the Electrogefest in the 1880s. They are considered the inventors of modern welding apparatus.
A. Mozhaysky was a Russian naval officer, aviation pioneer, researcher and designer of heavier-than-air craft. He constructed his first airplane in 1883.
A. Popov, a Russian physicist, was the first person to demonstrate the practical application of electromagnetic radio waves. Beginning in the early 1890s he continued the experiments of other radio pioneers, such as Heinrich Hertz, and in 1894 he built his first radio receiver, a version of the coherer. Further refined as a lightning detector, it was presented to the Russian Physical and Chemical Society on May 7th, 1895 — the day has been celebrated in Russia as Radio Day. In 1896, he demonstrated transmission of radio waves between different campus buildings in Saint Petersburg. He demonstrated ship-to-shore communication over a distance of 6 miles in 1898 and 30 miles in 1899. However, it is Guglielmo Marconi, an Italian inventor, who is believed to be the father of long distance radio transmission in Europe and the USA.
