Semyon Ivanov

Inventor of the Soviet system of stereoscopic glasses-free cinematography. He worked in cinematography since 1937 (NIKFI, «Soyuzdetfilm» film studio, in 1944-1947 - «Stereokino» film studio), since 1948 - in the stereo cinema laboratory (at NIKFI). In 1935 he invented a system of glasses-free stereoscopic cinematography using an opaque slit screen. Soon the system was patented in England, Denmark, Italy, Norway, France, Czechoslovakia, Sweden and other countries. In 1941, for the demonstration of stereo films according to the Ivanov system, the Moskva cinema was reequipped, in which a screen with a wire raster was installed. On February 4, 1941, a regular demonstration of stereo films began, the first of which was the «Concert». In 1960, he invented a multi-lens camera, on the basis of which cinema equipment for integrated stereoscopic shooting was developed.
