Rodolpho Theodor Wilhelm Gaspar von Ihering (born Taquara, 17 July 1883; died 15 September 1939) was a Brazilian zoologist and biologist, who is considered to be one of the founders of pisciculture in Brazil.
[2] In 1917 Hermann von Ihering was dismissed from his position of director of the Museu Paulista on Brazil's entry into World War I on the Allied side.
In protest, Rodolpho left the museum and opened a small metalworks factory, Fábrica Santa Izabel, where he worked for the next ten years.
In 1926 and 1927 he began to work in the Parasitology laboratory of the School of Medicine of the University of São Paulo, which had been established by the entomologist Lauro Pereira Travassos.
It was dedicated to the study of the breeding biology of fish of the region of the State of São Paulo, especially of the Billings Reservoir, and of rivers in Mogi Guaçu, the Tietê and the Piracicaba.
