Karl Georg Friedrich Rudolf Leuckart (October 7, 1822 - February 6, 1898) was a German zoologist who was born in Helmstedt. He was a nephew to naturalist Friedrich Sigismund Leuckart (1794-1843).

He earned his degree from the University of Göttingen, where he was a student of Rudolf Wagner (1805-1864). Afterwards he participated on a scientific expedition to the North Sea for the study marine invertebrates. Later he became a professor of zoology at the University of Giessen (1850) and the University of Leipzig (1869).

Leuckart is remembered for his work in parasitology, particularly research regarding tapeworm and trichinosis. He was the first to prove that Taenia saginata occurs only in cattle, and Taenia solium occurs only in swine. His study of Trichina helped support Rudolf Virchow's campaign to create meat inspection laws in Germany.^[1] With Virchow and Friedrich Albert von Zenker (1825-1898), he was the first to document the life cycle of the parasite Trichinella spiralis in swine and humans. He also did important studies of the sheep liver fluke.

Leuckart is credited with splitting George Cuvier's Radiata into two phylum; Coelenterata and Echinodermata. Between 1877 and 1892, he developed a series of zoological wall charts which have been used worldwide as teaching aids. As a scientist, his excellent descriptions of morphologic details gave credence to the idea that zoological evolution can be learned through its anatomical changes. Today the "Rudolf-Leuckart-Medaille" is an annual award given for research in parasitology by the Deutschen Gesellschaft für Parasitologie (German Society of Parasitology).

A quote attributed to Rudolf Leuckart:

It is not possible for man, as a thinking being, to close his mind to the knowledge that he is ruled by the same power as is the animal world. Like the despised worm he lives in dependence upon external commands, and like the worm he perishes, even when he has shaken the world through the power of his ideas

—Rudolf Leuckart
