HANNOVER, ADOLPH (1814–1894), Danish scientist and physician, known for his experimental studies in histology and microscopic technique. Hannover's detection of a plant parasite on the salamander was of vital importance to medicine for it proved for the first time the significance of vegetative contagious matter in the transmission of infectious diseases. Hannover's use of chromium acid as a hardening agent contributed to microscopic technique. His treatises on the microscopy of the nervous system, on the construction of microscopes, on the retina, and on the nature of cancer were translated into many languages.
