Alekander Stoletov (1829-1896)
Aleksandr Stoletov was a Russian physicist born August 10th, 1839. He was known as the founder of electrical engineering and studied the laws and principles of the Photoelectric effect. The Photoelectric effect is the observation that most metals emit electrons when light shines upon them, first discovered by Heinrich Hertz in 1887. Stoletov was the first to show that with the increase of the magnetic field, the ratio of magnetization to a magnetizing force of iron grows, but then begins to decrease. He died May 27th, 1896 at the age of 56. Stoletov was born in Vladimir, Russia, and was the brother of General Nikolai Stoletov of the Imperial Russian Army. In 1872, he defended his doctoral dissertation and became a professor at Moscow University a year later. In 1881, he represented Russia at the first World Congress of Electricity in Paris, where he presented his work on links between electrostatic and electromagnetic values.
