Holographs
The idea for holographs came about when British scientist Dennis Gabor developed the theory while working on the improvement for the electron microscope. He later received a Nobel Prize in 1971 in Physics. "Holos" means "whole" and "gramma" means "message" and the combination of the two Latin terms made the word "hologram."

With the invention of the laser in 1960, the initial problems with making a holographic image due to poor light sources became a solution that made holograms possible. Russian scientists N. Bassov, A. Prokhorov and American scientist Charles Towns worked to perfect the holograph.

In 1967 the first hologram was made of a person. Lloyd Cross combined white-light transmissions with cinematography in 1972 to create 3D images that moved. Holographic film was used to record with 2D frames.

Later improvements of the holographic continued to be made in Russia. A world-wide holographic image became a part of popular culture when George Lucas used a hologram in the first Star Wars movie (1977) to transmit Princess Leia's plea for help to Obiwan Kenobi through the android robot R2D2.
