Obukhovskaya hospital was founded in 1779; originally it had 60 beds and included "Dolgauz,” the first psychiatric institution in the city. It was named after Obukhovsky Avenue and Bridge. The first stone building was the men’s wing (1784, architect L. Ruska), then the women’s wing (1836-39, architect P.S. Plavov) was added and in 1866 two more wings were added, one of which was called the Prince’s Wing in honour of the Prince P.G. Oldenburg. In 1829 the first school for medical attendants was attached to the hospital. The transformation of the Obukhovskaya Hospital into a cutting edge scientific clinical institution was carried out by chief doctor A.A. Nechaev (1890-1922). From 1922 the hospital was called Nechaev Obukhovskaya Hospital in memory of the 9th of January 1905 (during the events of 1905, wounded demonstrators were admitted into this hospital). In the 1920s-30s it served as the clinical base for medical institutes and the Institute of Experimental Medicine; in 1932 higher medical courses were attached to the Obukhovskaya Hospital (from 1935 the District Courses, and from 1936 the Third Leningrad Medical Institute). In 1940 the Military Naval Medical Academy (see Military Medical Academy) was formed on the basis of Obukhovskaya Hospital as a medical institute. N.F. Arendt, I.I. Grekov, V.M. Kernig, A.A. Troyanov, and others worked at the hospital. On the territory of the hospital there is a monument to N. I. Pirogov; there are memorial plaques to I.I. Grekov, A.P. Kolesov, A.V. Melnikov, N.S. Molchanov, A.A. Nechaev on the buildings; in the vestibule of the former women’s wing (47 Zagorodny Avenue) there is a memorial plaque to Z.M. Volynsky.
