Alexandre Alexeieff (18 April, 1901–9 August, 1982) was a famous inventor who worked in the pinscreen that was made use in the making of films. The film shots usually use a white board which is known as pinscreen. He used extraordinary black board in his films. The length that was possessed by this board is nearly three to four feet.
This means that about millions of pins are easily headed on that board. After the complete covering the board with the pins, entire black surface, appears in the front. Hence in this way, many protocols are needed to be followed for making black boards with pinscreen. He made the first and foremost important protocol that consisted of perforated kind of grid where pins get easily inserted.
He was also famous for the screen pictures that were made by him because he never drew sketches and worked directly on the pinscreen board for his drawings. He perceived pictures on both sides of the screen.
