Burmeister ( 1807-1892 ), a German zoologist and geologist was born in Stralsund and completed his studies at the University of Halle and Greifwald in 1829. Under the auspices of Alexander von Humboldt, Burmeister traveled to Brazil from September 1850 to March 1852 where he studied natural history in the states of Minas Gerais and Rio de Janiero. In the fall of 1856, Burmeister returned to South America to study natural history in the Republics of Argentina and Uruguay. He became the Director of the National Museum of Natural History in Buenos Aires in 1862 where he worked for thirty years until his death. Burmeister is noted for his pioneering studies of trilobites and ungulates. Within his early systematic study "Organization of Trilobites" he provides an arrangement of the species of trilobites, discusses the structure of the body and the affinity of the trilobites to existing Articulata. The author includes a very useful bibliography of the known works on trilobites. The work is now quite scarce.
