Neisser began to study medicine at the University of Breslau, but later moved to Erlangen, completing his studies in 1877. Initially Neisser wanted to be an internist, but did not find a suitable place. He found work, however as an assistant of the dermatologist Oskar Simon (1845–1892), concentrating on sexually transmitted diseases and leprosy. During the following two years he studied and obtained experimental evidence about the pathogen for gonorrhea, "Neisseria gonorrhoeae".
