PIONEERS OF RUSSIAN ELECTRICAL ENGINEERING

Today more and more is done by electricity. It is used everywhere: in our plants and factories, in the fields, on trans­port, and in our homes. Electricity gives us music and news by radio. It does hundreds of other things. The wide application of electricity in the national economy and everyday life has become possible thanks to the rapid growth of electrical engi­neering, which began in the second half of the 19th century. The pioneers of Russian electrical engineering were Yablochkov and Lodygin — two great Russian scientists and inventors. Yablochkov's electric candle which had been called "Russian candle", "Russian Light" was the beginning of the practical application of the electric arc for lighting purposes. Working at his invention, Yablochkov recognized the advantages of the a.c. He was the first to design the a.c. transformer and put it into practice. Yablochkov's great technical achievements opened a way for a much more efficient source of light — the incandes­cent filament lamp. The idea of this lamp belongs to Lodygin. He devoted almost all his life to the perfection of his invention. He was never satisfied with his achievements. He constructed a number of incandescent lamps. He carried out a series of experiments to find the best metal filaments with a high melt­ing point. It was his idea to introduce tungsten filaments in vacuum. This invention was of world importance. It gave rise to a real advance in the field of electric lighting.

Like many other scientists and inventors Yablochkov and Lodygin got neither support nor help from the tsarist govern­ment. They died in great need.
