Lebedev generated 50 GHz millimeter waves using spark oscillator in 1895. Lebedev detected waves with thermocouple and demonstrated refraction, diffraction, polarization. Lebedev extended Hertz experiments to millimeter waves with quasioptical components. Lebedev measured light pressure on solid body first in 1899. Lebedev's measurement quantitatively verified Maxwell's theory predictions. Lebedev confirmed light pressure on gas matches Maxwell in 1909. Lebedev created Russia's first scientific school. Lebedev earned doctorate in Strasbourg under Kundt 1887-1891. Lebedev worked at Moscow State University from 1891 under Stoletov. Lebedev became MSU professor in 1901. Lebedev quit MSU in 1911 protesting Ministry politics. Lebedev rejected Stockholm professorship in 1911. Lebedev died 1912 from hereditary heart condition.
