Creating holography: 75th anniversary of Gabor’s invention

The year 2022 marks the 75th anniversary of Dennis Gabor’s invention of the holographic method and for which he received the Nobel Prize in Physics in 1971. The year 2022 also marks the sixtieth anniversary of the publication in 1962 of two seminal papers in the field of holography. In one of them Yuri Denisyuk introduces the reflection hologram and in the other paper Emmeth Leith and Juris Upatnieks describe the holographic process from a communication- theory viewpoint. In this paper, we carry out a brief description of the different “origins” of holography, making special mention to the way Gabor, Denisyuk y Leith established the basis, which made possible the spectacular development of holography from the invention of the laser at the beginning of the decade of 1960.
