     History

     In 1947 Dennis Gabor, an English research scientist of Hungarian
     origin, was working on a technique to improve the electron
     microscope. Working with some theoretical calculations, he invented
     the principle of holography: to record the phase of a lightwave by running
     another lightwave into it. Although he even succeeded to produce some
     kind of hologram (a very small one), to make it work properly there was
     one thing still missing: the right lightsource.

     To make a hologram you need coherent light; this is light in which all the
     waves are going up and down simultaneously. Trying to produce this,
     Gabor used a bright mercury-vapour light shining through a tiny pinhole.
     The results were very poor. With the invention of the laser in 1960 it
     became possible to make holograms (laserlight is completely coherent).
     With this light, Gabor’s invention could be put into practice. Since then,
     the technique has improved immensly, and will continue to improve in
     the future. You will definitely see more and more of it in years to come....

     Dr. Dennis Gabor was awarded the Nobel Prize for Physics in 1971.

     The first hologram gallery in Amsterdam opened in 1988:
