Gabriel Lippmann : 


Pioneer in photography 



Gabriel Lippmann (1845-1921) developed a method of capturing coloured images in black-and-white photographic emulsions. His stunning invention, now called Lippmann colour photography, was based on the phenomenon of light interference in thin films. In hindsight, it is straightout unbelievable that this advanced photographic process was developed as early as 1891, after years of patient experiments.
His invention gained Lippmann the Nobel prize for Physics in 1908.
Lippmann's invention was the precursor of Yuri Denisyuk's volume reflection holography. See chapter 7 of Optical Document Security, 3rd edition.
