Robert B. Goldschmidt (1877–1935) was a Belgian chemist, physicist, and engineer who first proposed the idea of standardized microfiche (microfilm). Goldschmidt was a polymath who also made advances in aviation and radio, among other fields. In 1913 he constructed a major radio facility at Laeken, Belgium, where in 1914 he and Raymond Braillard inaugurated Europe's first regular radio concert broadcasts. He was also a participant in the first and second international Solvay Conferences reviewing outstanding issues in chemistry and physics.
