Botanist (1863–1896).
Rudolf Raimann (1863 – 5 December 1896 in Vienna) was an Austrian botanist. In 1889 he received his doctorate from the University of Vienna, where his influences included botanist Julius Wiesner. He worked as a volunteer in the department of botany at the Imperial Natural History Museum, and for a period of time taught classes in natural history at the Handelsakademie (school of business and commerce) in Vienna. The plant genus Raimannia (J.N. Rose ex N.L. Britton & A. Brown, 1913) of the family Onagraceae commemorates his name.
