|Dennis Gabor (1900-1979) is the inventor of holography. To acknowledge his creativity and scientific insight, he was awarded the Nobel Prize for Physics in 1971.|
Yuri Denisyuk is credited with recording the first 3-D holograph back in 1962. Here is a 3-D hologram from the NTT DoCoMo R&D Center in Yokosuka, Japan. Wikipedia and How Stuff Works are good sources to learn more about types of holograms and how they are used in security.
