As we know, the first report on photographic plate hydrogen hypersensitisation (hypering) is dated 1871 (U.S. Patent No. 113327, April 4 1871, see Janusonis et al. 1978). A new interest in the topic appeared in the 1930s, after the work of Robert Kozlowsky at Agfa Wolfen. Kozlowsky was the inventor of gold sensitization. In the 1950s in Russia the action of hydrogen on thick nuclear emulsions was also studied (Tschernyavsky et al. 1962). Strong fogging, especially at increased temperatures, was observed.
