Holography
Holography is photography in three dimensions and more! It was first proposed and the basic theory developed by Dennis Gabor (1971 Nobel Prize for this work) in 1947 as a tool to improve the resolution of the electron microscope but did not really amount to very much until the development of the laser in the 1960's. Gabor named it from the Greek words for whole (holos) and message (gramma). In 1964 Emmett Leith and Juris Upatnieks of the University of Michigan made the first hologram (of a train and a bird, seen below), a true three-dimensional image of the original objects.
