Revealer GmbH is a company founded in 2018 by Tiago Romagnani Silveira and Thomas Voegtlin, with the mission of producing backup solutions.
Revealer originated as an artwork in homage to Emanuel Goldberg. Created to celebrate cryptography as a trait of nature and as a tool for individual sovereignty, the artwork aimed to improve public understanding and awareness of cryptography.
Emanuel Goldberg (Portrait) was born in Moscow, Russia, in 1881, a chemist, inventor, and industrialist who contributed to almost all aspects of imaging technology in the first half of the twentieth century: photographic sensitometry, reprographics, standardized film speeds, color printing (moiré effect), aerial photography, extreme microphotography (microdots), optics, camera design (the Contax), the important, early hand-held Kinamo movie camera, and early television technology. He received his doctorate from Wilhelm Ostwald’s institute in Leipzig in 1906.
The “Goldberg condition” is a design principle for photography and movie sound tracks.
In 1933, when head of the world’s largest camera firm, Zeiss Ikon in Dresden, Germany, he was kidnapped by Nazis and disappeared into oblivion. In fact, he went first to Paris and then to Tel Aviv, where he set up a precision instruments workshop, which became a major Israeli firm, El-Op. He died in Tel Aviv in 1970.
In 1931 he demonstrated in Dresden, London and Paris a “Statistical Machine” which combined photocell, circuitry, and microfilm to make a search engine to find and display stored documents. (Description). His paper on it appears to have remained uncited for fifty years. Vannevar Bush attempted to build a similar machine in 1938-1940, calling it a Microfilm Rapid Selector. Bush’s fantasy on what such a machine might do, “As we may think”, became famous. Goldberg and his machine were forgotten. (Article on Goldberg, Bush, and retrieval).
Goldberg lived in distant worlds during exciting times: Czarist Russia; the Kingdom of Saxony; the Weimar Republic; Palestine under the Mandate. He did not reminisce much, even to his children; the records of his firms were destroyed by bombing (Dresden) and flood (Israel); his writings are often in obscure German publications; he burned most of his own papers. His successors (Nazis and communists) did not honor Jewish capitalists. Some contributions in Israel are still classified.

The artwork was created with support from the Elsa-Neumann Scholarship from the State of Berlin. It was presented at the Technical Collections of Dresden and at the Hamburger Bahnhof in Berlin. You can find video documentation of the installation below.
